The traditional optimization design is only based on the minimum cost objective function and does not consider the mechanical analysis target.

传统的优化设计仅以最低造价为目标函数，没有考虑结构的受力性能指标。

In any case, if the target Part number already exists, then the Assign function will simply link the Design to this existing Part.

无论如何，假如目标物料号已经存在，那么安排函数将会简单的链接设计到这个已经存在的物料。

The first optimum model is established with the target function of the frame's weight as well as with the design variables of the beam's single layer thickness.

首先以纵梁各部分单层厚度为设计变量，建立了以车架重量为目标函数的优化模型并进行了优化研究，取得了较好的优化效果。
