Research on weight lighting for bus body frame based on optimization of parameter |
| |
| Abstract: | To research on weight lighting for bus body frame by means of finite element method, mathematical programming method,it establishes the optimized design mathematical model of bus body frame, introduces its ANSYS realizing process,make an optimizing design of parameter by combining a certain typical bus body frame. It obtains a better weight lighting effect by mitigating its weight about 14.5% under the precondition of ensuring its original frame carrying capacity. |
