Bolt Pretension

Available for 3-D simulations only.

Applies a pretension load to a cylindrical face, to a straight edge of a line body, to a single body, or to multiple bodies, typically to model a bolt under pretension. If you apply the Bolt Pretension load to a body, you will need to have a local Coordinate System object in the tree. The application of the load will be at the origin and along the z-axis of the local coordinate system. You can place the coordinate system anywhere in the body and reorient the z-axis.

Another option for applying the load to a line body is to apply it to a single straight edge on the body. The direction of the bolt load is inferred from the direction of the edge.

把负载应用于一线性结构体的另一种选择是把它应用于结构体上的单一直边

梁应该归类为 solid body：实体

在此为何是 line body：线体

梁单元是通过对线体离散化得到的~
单元，节点是有限元模型的概念；
线，面，体是几何模型概念。
