Body

介绍

Body类专门用于雕刻建模，它可以生成复杂形体的网格，虽然无法得到准确的模型细节，但可以再设计初期得到相对准确的刚度和质量信息，以便进行系统级的模型动力学分析。

类结构

输入 input：

Meshsize : 网格大小
Space : 空间尺寸

参数 params:

Name : 名称
Material : 材料

输出 output :

Assembly : 装配体
SolidMesh : 实体网格
OriginSolidMesh ：平滑前实体网格
Times : 雕刻次数

案例

以一个风电扭力臂为例，图片来自于德利佳官网3~3.6MW平台 http://www.dljtransmission.com/ctt/1/89.htm ，风电扭力臂用来传递扭矩，观察图片，两端支座用以连接支撑，中间连接轴承，上端增加两吊耳用以吊装，同时增加加强筋增大局部刚度。
