Structural Modal Analysis and Optimization of Mini-car Doors Based on Response Surface Method
摘要
Abstract
Sensitivity analysis method and response surface method were used to optimize struc-tural modal of the mini-car doors.A finite element numerical simulation model was established,and the simulation model was calibrated by restraint modal tests.In order to screen out high sensitive plates,a sensitivity analysis for the thicknesses of door plates was proposed based on door's third or-der modal frequency.Sample points were obtained by face centered composite design while design var-iables were from the thicknesses of high sensitive plates,and a two order explicit response surface function of vehicle door's third order modal frequency was established.According to the response sur-face function,an optimization model was established.The final results show that the modal frequency matching of the door and body in white is optimized after changing the door thicknesses,while materi-als are saved about 5.83%.关键词
