Crash Analysis of Bumper Assembly with Solver to Improvise the Design for Impact Tests

ABS, PETG, TPU, CATIA, Solid Works and stress analysisAbstract
Car bumpers can deform to absorb impact energy. For static and modal analysis, a Benz vehicle bumper was used. These analyses used a variety of bumper materials, including glass-mat thermoplastic, aluminium alloy, and mild steel with chromium plating (GMT). The majority of modern cars have bumpers composed of PC/ABS, a material blend of polycarbonate (PC) and Acrylonitrile butadiene styrene (ABS). PETG, ABS, and TPU. The deformation and strains grow as the car's speed rises from 55 km/hr to 90 km/hr, according to the static study. At a car speed of 75 km/h, the deformation and stress in the automobile bumper were at their highest. It was found through the static analysis that the stress values for PP material were lower.
