Pune is a developing metropolitan city not only emerging as an international education hub but also as an IT and an ITES research and development centre, which attracts in migration of population in the city. The Population of Pune city is approximately 40 lacs and has registered 10, 70,000 vehicles. The survey which was conducted by PMC shows that volume to capacity ratio of the existing roads is more than 1.00 in peak hours. In this urbanized city, there is growing multi-modal commuting activity (public bus transport, two-wheelers, three wheelers, cars, and others). This activity is largely local, but rapid urbanization is increasing its traffic within the city. It is observed that, road public transport system in Pune city is not efficiently working as estimated because the existing roads do not have the capacity to carry vehicular load and high demand of traffic density. Hence, there is a need to study the traffic density to minimize the traffic congestion for efficient movement of traffic. With the available road width, as there are no chances of road widening possible, constructing a metro bridge at most congested routes is the only option to solve the traffic problems. In this project, the study is mainly focusing on analysis of advanced techniques for design of precast segmental box girder viaduct. The construction of metro rail bridge is one of the long term strategies for safe and efficient movement of commuter’s flow which provides fast, safe and non polluting way of transport system. The proposal of a precast segmental viaduct design is technically feasible as there is continuous traffic flow with limited availability of Right Of Way. An extensive study of all the parameters involved in the design of the bridge will be made. The project concisely summarizes the economical design of the bridge.

The following report encompasses the design of braking system. The system is one based on hydraulic braking and designed for a one-man performance racing vehicle. The objective of the system is to convert the kinetic energy of the vehicle into thermal energy, allowing the vehicle to decelerate optimally and safely. The design includes three major categories: calculation and evaluation of the hydraulic system in order to select callipers and master cylinders, the design of the pedal box, and the design of the rotors. The results and findings of the proceeding report rendered a symmetrical front and rear braking system. The Wilwood GP 200 two piston floating calliper and the Wilwood flange mount master cylinders with a ¾’ inch bore was selected for the system. An optimized pedal box was designed consisting of two pedals, (Acceleration and brake), eight mounting tabs for the two pedals and master cylinders, and two electrical sensors supports (one for the brake light sensor and the other for the emergency stop switch). The pedal box was optimized for minimal mass and satisfied the design criteria (later defined in the text). Lastly, custom rotors were designed based on the optimal material choice, analysing thermal effects and considering cost.

A new design technique for designing multi-leaf springs is the subject of this research paper. Automobile industries always search for alternatives to reduce the mass of the vehicle, to increase its performance. A new approach is used for reducing the mass of a conventional multi-leaf spring, and also enhancing its fatigue life. The new spring made by using this approach is called ‘VKP spring’. Stress, strain, and total deformation are the designing constraints. 55Si2Mn90 steel and E-Glass/epoxy are used to compare the results of fatigue life of multi-leaf springs, at a range of loads. Modeling is done using FUSION 360 and ANSYS 15 is used to perform static structural analysis. ----------------------------------------------------------------------***--------------------------------------------------------------------1.

Austenitic Cast Iron (Ni-Resist) is widely used for products with wear and corrosion resistance. The wear and corrosion resistance can be improved by heat treatment so that it has longer lifetime. The purpose of this research is to find out the appropriate heat treatment so that wear and corrosion resistance is optimal.Heat treatment is carried out normalizing, quenching and tempering (200 o C and 400 o C) on austenitic cast iron with the main alloy 17% Ni; 3,06% C; 2,77% Si and 2,13% Cr. The formation of austenite structures can improve wear and corrosion resistance. Tests carried out include wear resistance, corrosion resistance and micro analysis in as-cast and after heat treatment.The wear rate of the as cast is 1,34E-4 mm 3 /kg.m. Heat treatment increases wear resistance by 31% (normalizing), 63% (quenching), 88% (tempering 200 o C) and 75% (tempering 400 o C) compared to as cast. The corrosion rate of the as cast is 9,15E-5 mpy. Heat treatment decreases corrosion rate by 38% (normalizing), 52% (quenching), 29% (tempering 200 o C) and 14% (tempering 400 o C) compared to as cast. Increased wear and corrosion resistance occur due to changes in microstructure and graphite size.

Now a days there is a tremendous change in the climatic conditions due to global warming and greenhouse gases results in the floods, draughts and famine. More usage of petrol & diesel in vehicles, leads to poisonous gases enters into atmosphere results in environment become hazardous. Carbon Dioxide is one of the major components of Greenhouse gases which results in greenhouse effect. More amount of Carbon Dioxide releases from burning of petroleum based products which are emitting from the Vehicles and Industries. For the control of the emission of the carbon dioxide into the atmosphere we have chosen for adsorption of Carbon Dioxide from the exhaust of the gasoline vehicles using Zeolite. The gasoline vehicle used for testing is following the EURO – V emission norms and the Carbon Dioxide content releasing from the vehicle is reduced by more than 25%.

With the increasingly strict requirements for diesel engine emissions and the maturity of high-pressure common rail injection technology, the requirements for nozzles in the industry are also increasing. The quality of the nozzle hole has great influence on the performance of the diesel engine. Therefore, how to improve the quality of nozzle hole processing and improve production efficiency has become a problem to be solved. In this paper, based on the theory of high-speed metal micro-cutting, using digital design and computer simulation, the drilling of diesel engine injector nozzle holes is studied. The research contents include the chip formation mechanism and the characteristics of drilling process. The research objectives are as follows: based on the experiments of nozzle hole drilling, the relationship between drilling characteristics and drilling parameters in the process of nozzle hole drilling is studied; the formation process of nozzle hole chip is studied. In drilling simulations, 20CrMo is used as workpiece material and carbide micro-bit is used to process the nozzle holes. Third Wave Advantedge finite element simulation software is used in the simulation.

The utilization of concrete has been increasing day by day due to rapid industrialization, urbanization and infrastructural developments all over the world. A huge quantity of natural coarse aggregate, natural river sand and also cement is needed in order to fulfill the increasing demand. This is causing a rapid depletion of the natural resources, be it rocks for coarse aggregate or the natural river sand and need to be conserved urgently. It is also found that during the production of cement, an equal amount of carbon dioxide is also produced and to overcome the ill effects caused on the environment, attempts have been made to replace the natural resources by some other materials such as recycled aggregates and ROBO sand and cement by some other binding material like bentonite. This work reports the results of an experimental study on the mechanical properties of concrete produced with recycled coarse aggregate (100%), ROBO sand (100%) and partial replacement of cement with Bentonite (0%, 5%, 10%, 15%, 20%, 25% and 30% replacement). The compressive strength, split tensile strength and flexural strength of this concrete was tested by casting cubes of size 150 X 150 mm, cylinders of diameter 150 mm and length 300 mm and beams of length 500 mm and cross sectional dimensions 100 X 100 mm size respectively and testing was done at 7 and 28 days. The fresh and harden concrete properties were analysed after 28 days of curing and found that at 20% replacement of OPC with bentonite along with super plasticizer was optimum and gave compressive strength of 44.0 N/mm2 which is an increase of about 17.5%.Similarly the split tensile strength is found to12% more than at 0% bentonite.. The workability was a problem initially but was able to achieve after addition of super plasticizer.

_______________________________________________________________________________________ Abstract The incorporation of soil structure interaction effect in the analysis is complex and time consuming. In this work an attempt is made to derive an empirical equation to evaluate storey displacement under the influence of SSI effect using the results of storey displacement obtained from fixed base condition. An attempt is also made to check the accuracy of empirical equation by comparing the results with the incorporation of soil structure interaction effect using elastic continuum model. The results obtained from empirical equation are compared with the elastic continuum model using application software SAP2000. Study reveals that the empirical equation is reasonably correct and can be used to estimate storey displacement of mid rise building frames considering soil structure interaction. Thus the complexity involved in the SSI modeling may be reasonably substituted using simple empirical equation.

Ultra High Molecular Weight Poly Ethylene (UHMWPE) is a plastic biomaterial developed and had been used for decades in biomedical applications. This material is commonly produced with machining processes. One of those process is the milling operation. This method is needed alongside with the more common turning operation since there are many implant designs are not geometrically cylindrical. The milling process like any other machining techniques requires the operators to set certain machining parameter values to achieve specific objectives. One of these is the surface roughness of the materials. Rough machined surfaces were suspected to harbor more bacteria when the implant products made from UHMWPE are being used inside the human body. This study tested the influences of feed rate and depth of cut machining parameters on the UHMWPE surface roughness. The milling machining process with a SIEMENS CNC machine on the UHMWPE biomaterial was proved capable to produce better surface finish qualities. Four feed rate values between 0.2 mm/rev. to 0.025 mm/rev. and three depth of cuts from 0.2 mm down to 0.05 mm were evaluated. Third machining parameter, i.e. cutting speed was set constant at 150 m/minute. The tool is the high speed steel end milling. Achieved minimum surface roughness was found below 2 microns. A multiple regression model was developed to guide the machine tool operators to determine proper machining parameters. Statistical tests conducted and it can be concluded that feed rate is the most influential parameter. It must be set 0.05 mm/rev. or lower in the purpose to obtain higher quality surface finish.

Third machining parameter, i.e. cutting speed was set constant at 150 m/minute. The tool is the high speed steel end milling. Achieved minimum surface roughness was found below 2 microns. A multiple regression model was developed to guide the machine tool operators to determine proper machining parameters. Statistical tests conducted and it can be concluded that feed rate is the most influential parameter. It must be set 0.05 mm/rev. or lower in the purpose to obtain higher quality surface finish.","PeriodicalId":14258,"journal":{"name":"International Journal of Research in Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89928612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
