Meanw hile,through adopting the fuzzy optimization method,taking the total w eight of both front and rear frames as the objective function and regarding the maximum stress on each steel plate of the frame as the constraint conditions,the equal strength optimization of frame structure w as carried out. In addition,the stress distribution of the frame before and after optimization w as compared. The results show that after the improvement and optimization of frame structures,the maximum stress value drops by 112 MPa,and the w eight reduces by 96 kg. Furthermore,the stress distribution is more uniform than that before the optimization.Read More
