Abstract
This paper elaborates on the modal analysis and comparison of truck chassis frames made of composite materials (Carbon/Epoxy and E-glass/epoxy) and mild steel using the finite element method (FEM). All the specifications of the vehicle were taken from Bishoftu Automotive Industry, Ethiopia. Weight reduction has been achieved by 79.48% and 66.67% for carbon/epoxy and E-glass/epoxy respectively. The modal analysis shows that the first six natural frequencies of carbon/epoxy, E-glass/epoxy and mild steel are in the ranges from 56.8Hz to 134.8Hz, 27.22Hz to 64.59Hz and 31.97Hz to 75.88Hz respectively. The first two natural frequencies for carbon/epoxy and all-natural frequencies for E-glass epoxy and mild steel are in the engine excitation range. The main disturbance is due to the road excitation which ranges from 0 to 100 Hz, which is even greater than the engine excitation. Carbon/epoxy is the best candidate that some of its natural frequencies are above the engine and road excitations as compared to steel and E-glass epoxy chassis frames.
期刊介绍:
The International Journal of Vehicle Structures and Systems (IJVSS) is a quarterly journal and is published by MechAero Foundation for Technical Research and Education Excellence (MAFTREE), based in Chennai, India. MAFTREE is engaged in promoting the advancement of technical research and education in the field of mechanical, aerospace, automotive and its related branches of engineering, science, and technology. IJVSS disseminates high quality original research and review papers, case studies, technical notes and book reviews. All published papers in this journal will have undergone rigorous peer review. IJVSS was founded in 2009. IJVSS is available in Print (ISSN 0975-3060) and Online (ISSN 0975-3540) versions. The prime focus of the IJVSS is given to the subjects of modelling, analysis, design, simulation, optimization and testing of structures and systems of the following: 1. Automotive vehicle including scooter, auto, car, motor sport and racing vehicles, 2. Truck, trailer and heavy vehicles for road transport, 3. Rail, bus, tram, emerging transit and hybrid vehicle, 4. Terrain vehicle, armoured vehicle, construction vehicle and Unmanned Ground Vehicle, 5. Aircraft, launch vehicle, missile, airship, spacecraft, space exploration vehicle, 6. Unmanned Aerial Vehicle, Micro Aerial Vehicle, 7. Marine vehicle, ship and yachts and under water vehicles.
