车用铝合金榫卯结构优化设计
Optimal Design of Automobile Aluminum Alloy Mortise and Tenon Structure
摘要
Abstract
A semi-rigid method for analyzing mortise and tenon joints was designed according to the characteristics of mortise and tenon joints of vehicles.Spring element was introduced in the optimization process of automobile frame,and the quadratic polynomial response surface was fitted by APDL and MATLAB.The maximum stress and the weight of the response surface of the structure mass after fitting were taken as the design objective,and the optimal solution was obtained by using linear weighting algorithm.The reserch shows that the maximum stress is reduced by 10.8%and the frame mass is reduced by 6.4%and the energy absorption is increased by 7.48%when the ultimate stress constraint is met,which not only improves the safety performance of the vehicle,but also realizes its lightweigt.关键词
