客车结构优化设计

把灵敏度分析引入到客车结构优化设计中，通过对某型客车各梁的相关参数相对于整车质量变化的灵敏度分析，找出对质量变化最敏感的设计参数，再对其进行尺寸优化，计算出最优数值，根据型钢标准对优化结果进行圆整，从而得到改进后的尺寸，对客车结构的改进提供指导，提高优化设计的效率，减少其盲目性。

Optimization design of bus structure

Put sensitivity analysis into bus structure optimization design,through sensitivity analysis of complete quality transformation for the parameter of each beam of some model bus,finds out the most sensitive design parameter of quality,and then optimizes its dimension to calculate the optimized value, rounds for the optimized result according to profile steel standard,thereby obtains the modified dimensions,provides guidance for the improvement of bus structure,improves the optimization design effect,reduces its blindness.
