The present work explores a magnetorheological brake (MRB)-based anti-lock brake system (ABS) proposed for a vehicular application. Because of its quick response time, MRB is being considered as a substitute for the conventional hydraulic brake (CHB), commonly used for road vehicles. ABS is used along with CHB to prevent wheel lockup due to severe braking and thereby maintain the stability of the vehicle. This work envisages ABS for a vehicle using MRB instead of CHB. The braking maneuver for a typical mid-size car with and without ABS is simulated in a MATLAB environment. Both versions, a CHB-based ABS and a MRB-based ABS are considered in simulations. The braking performance in terms of stopping time and stopping distance is estimated. A PID and a Fuzzy controller are proposed for improving the control performance of the brake system. The comparative analysis based on the simulations helps make estimations for MRB-based ABS performance.

Sequential micro machining (SMM) is a strategy of machining applied for micro-part manufacturing. Due to the finding of new sequential machining combinations, the authors have presented a novel combination of micro-ECDM (µECDM) drilling and micro-ECM (µECM) finishing for producing micro-holes in SS-304 stainless steel. An experimental setup was developed indigenously to conduct both machining processes at one station. The sequential processes were employed with desirable machining parameters, during their individual execution. The most desirable parameter like machining voltage, for hole drilling by µECDM was decided by studying hole taper angle, radial overcut, etc. The µECDM generates a recast layer, to overcome the adverse effects of µECDM, with the µECM finishing applied subsequently. The experimental results of SMM indicate a reduction in hole taper angle, improved circularity, and better surface quality. The change of phase of material due to sequencing of µECDM and µECM processes was analyzed by an XRD analysis of SS-304.

The present article theoretically and experimentally investigates free vibration characteristics of generalized curved beams with moving boundaries. The dynamic behavior is characterized about deformed configuration, attained under different concentrated loads, and rigidly connected to the midpoint of the beam. The coupled static and dynamic analysis of the geometric nonlinear problem is decomposed into two parts: the static problem dealing with large deformed configuration and the dynamic problem dealing with small amplitude free vibration of the deformed configuration beam. The analysis is carried out incrementally in embedded curvilinear coordinate frames using variational principle. The governing equation of the static problem is derived for a combined effect of bending and center line extension. The governing equation for free vibration is derived at the particular configuration of the updated beam geometry, using Hamilton's principle. The comparison between the numerical and experimental results successfully validates the proposed semi-analytical model and leads toward some meaningful observations.

The present work developed an environment in the cloud with IoT tools for the intelligent monitoring of cutting processes in a three-axis CNC machine. To achieve it, a group of sensors incorporated into the machine are connected to a data acquisition card in charge of sending the measurements delivered by the sensors to the IoT environment in the cloud. The data received was processed in real-time, and at the end of the machining, an automatic report was generated that includes: the cost of the operation, total process time, average energy consumption in watts, and positions of the X, Y, Z axes in function of time. The findings of this study bypass production managers from developing a processes sheet, reducing fabrication time, and increasing productivity. The architecture of the system was put to the test raising two case studies, which demonstrate the relevance and the significant impact of the platform in the new era of digital manufacturing.

In this work, a geometric model for tolerance analysis has been carried out. Geometric reasoning has been implemented in the model to simulate the manufacturing process and, then, the assembly sequence. The proposed geometric model has been applied to a case study consisting of two circular profiles due to the turning process, and a hollow rectangular box. The two circular profiles have been assembled inside the box by considering the gravity, and the friction among the parts and the actual points of contact with and without using the manufacturing signature. Matlab® software has been used to implement the geometric model for tolerance analysis. The results have been compared with those obtained by using a literature model with and without considering the manufacturing signature. This work aims to be a first step towards the integration of the design and the manufacturing in a concurrent engineering approach.

The wheelchair is essential for people with either spinal injury, limb injury, or trauma patients. The need at present is to customize the wheelchair based on the requirements of the disabled person. The maintenance and customization of a manual wheelchair is both simple and cost-effective when compared to powered wheelchairs, which are expensive and difficult to maintain in the long run. Accordingly, in this article, an attempt has been made to bring the facilities available in a powered wheelchair into the manual wheelchair, making it affordable to common people. Feasibility of a distinct manual wheelchair rear wheel rim is examined for various hub motor weights. The rear wheel of the manual wheelchair was replaced with an in-wheel direct drive hub-motor system. The proposed wheel model was designed using CATIA – V5 and an analysis was done using ANSYS software. A structural analysis was carried out to check the reliability and durability of the proposed wheel for different materials by changing hub-motor weights at various loading conditions. The nature of vibrations with respect to natural mode frequencies are found through modal analysis. Finally, the dynamic behavior of the proposed motorized wheel was examined using harmonic response analysis. Simulation results show the robustness of the proposed design and viability for real-time implementation.

This article investigates the effects of impact and compressive behaviors of impacted E-glass/epoxy and S-glass/epoxy composite elbow pipe joints. In a bid to measure the transverse impact and residual compressive strength, the composite elbow pipe joints were subjected to impact test at room temperature, followed by the axial compression test. Moreover, various impact energy levels of 10, 12.5, and 15 J were utilized to test the elbow pipe joints using an instrumented impact testing machine at room temperature. Results indicated that the force–deflection behavior and failure mechanism was more than impact energy with the type of material used. Compressive strength commonly decreases with the increase in the impact energy and the type of material used.

This article presents the investigations on deformation behavior in precision forming of thin sheet metal by laser pulses using finite element analysis. The temperature and deformation fields were estimated and analyzed in pulsed laser micro-forming of AISI 304 stainless steel sheet of rectangular and circular shape considering the effects of different process parameters such as laser power, spot diameter and pulse on time. Response surface models based on finite element simulation results were developed to study the effects of the process parameters on deformations for the rectangular and circular workpieces. The amount of deformation was increased with the increase in laser power and pulse on time, and it was decreased with the increase in spot diameter. The effects of pulse frequency and sample size on deformations were also explained. Experiments were conducted on pulsed laser micro-forming of stainless-steel sheet to validate the finite element results. The results of finite element simulations were in good agreement with the experimental results.

The knowledge of materials' mechanical properties in design during product development phases is necessary to identify components and assembly problems. These are problems such as mechanical stresses and deformations which normally cause plastic deformation, early fatigue or even fracture. This article is aimed to use particle swarm optimization (PSO) and finite element inverse analysis to determine Young's Modulus and Poisson's ratio from a cantilever beam, manufactured in ASTM A36 steel, subjected to a load of 19.6 N applied to its free end. The cantilever beam was modeled and simulated using a commercial FEA software. Constriction Factor Method (PSO variation) was used and its parameters were analyzed in order to improve errors. PSO results indicated Young's Modulus and Poisson's ratio errors of around 1.9% and 0.4%, respectively, when compared to the original material properties. Improvement in the data convergence and a reduction in the number of PSO iterations was observed. This shows the potentiality of using PSO along with Finite Element Inverse Analysis for mechanical properties evaluation.

Patients with diabetes often desperately need ankle foot orthotics (AFO) to perform daily activities. In Indonesia, experienced shoemakers employ manual procedures and follow the prescriptions given by a doctor or orthopaedic technician. This process remains traditional in that each pair of AFO is handmade, not precise, and is time consuming. This article describes the development of the design process and fabrication of a new AFO product for patients with diabetes based on a computer aided reverse engineering system (CARESystem). The reverse innovative design approach method discussed in this paper sought to achieve the best shoe last. The results also shows a functional test with highly satisfactory results. The shape of the shoe fit the standard AFO and the first patient experienced comfort for the 4-week long testing period. This article proves that the CARESystem technology successfully reduced the time for both the design and fabrication of the AFOs by 64%.
