摘要

对微型货车车身进行了轻量化改进,使整车质量总共减少10.9 kg,利用有限元前处理软件对模型施加约束和力后,进行了整车改进前后弯曲刚度和扭转刚度计算对比,发现弯曲刚度下降1.28%,扭转刚度下降2.49%,都略有下降,强化路面实车试验后,性能良好。

Abstract

Body improvement of lightweight mini-truck made vehicle mass reduction of 10. 9kg. After constraints and forces is carried out to calculate the bending stiffness and torsional stiffness around the vehicle in the pre-processing software of the finite element to model,in the contrast,it is found that the bending stiffness fell 1. 28 percent,and 2. 49 percent decline after the torsional stiffness,so they are down slightly. Tests of mini-truck is done on the real enhanced road,it is good performance.
