Application of One-step Forming in Crash Simulation of Automobile Seat
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 3
Abstract
To guide the design of car seats and save development time, this paper studied the effects of residual stress and plastic deformation generated after sheet metal parts stamping on the crash simulation of car seat based on one- step stamping, and investigated the automatic processing method of stamping process. Stamping simulation of sheet metal parts was conducted through the Radioss_One_Step module of Altair HyperWorks software. The program was optimized by TCL/TK and Python language, to achieve the automatic batch processing of stamping simulation of all sheet metal parts of seat, meanwhile, the stamping results was automatically mapped to crash model. This paper took the driver’s seat of a vehicle as research object to perform crash simulation and physical test of the 50th percentile male dummy. It is found that the rear impact simulation with the stamping results is closer to the physical test, the simulation is more accurate. Moreover, the optimized batch program can save more than 90% of the working time.
