摘要
在汽车设计生产中,为了能高效及时的分析车身材料的特性及其之间相互影响的关系,需要开发一款利用Matlab评估材料特性的软件。论文介绍了由各向同性材料制成的具有不同截面的杆件在受到多个线性叠加外部静载荷时强度校核的方法以及应力集中现象对强度的影响;其次简述了该强度校核过程在Matlab中实现的算法思路以及主要的算法流程;最后对软件计算结果和实际工程应用中的计算结果进行比较和误差分析,保证计算结果的可靠性。该算法的实现保证了汽车在实现轻量化生产的同时并没有损失其必要的安全性。
In order to realize the efficient and fast analysis of the properties of various materials in carrosserie, it is of realistic significance to take use of Matlab to assess the material properties. This article describes the methods of strength calculation, when the rods with different cross-sections, which are made of isotropic materials, are subjected to multiple linear superposition of external static load. Besides, the effects of stress concentration are also discussed in this article. What＇s more, the main ideas of the algorithm, which are used to implement the strength calculation of isotropic materials with Matlab, are presented after the theoretical basis. Finally, to ensure the reliability of the results,the results from Software and practical calculation are compared and the errors are analyzed. The implementation of this algorithm proves that the security of vehicles can be ensured during the realization of lightweight production.
