Simulation Analysis and Structure Optimization of Coach Front Crash Safety Performance
PENG Dongging
Abstract: The author carries out the finite element simulation analysis on the front crash safety performanceof the original structure of a coach.According to the simulation results,the author does the optimization tothe original front by adding energy-absorbing boxes and enhancing the frame strength and verifies the effectby simulation.The verification results show that the optimization design can effectively reduce the intrusionof the vehicle body structure into the driver's living space.
Key words: coach; front crash; living space; structure optimization
