Description

This command is used to define and position one or more bolts. Multiple bolts can be defined by referring to a TABLE. Each line in the TABLE then contains a coordinate for the bolt location and a vector defining its orientation. An example is given below.

Example

Define bolt component with specified position

Definition and positioning of a bolt in a hole. Node ID's $\mathrm{N}_1$=818 and $\mathrm{N}_2$=825 are located on opposite sides on the rim of the hole. The vector between $\mathrm{N}_1$=818 and $\mathrm{N}_3$=225 defines the axial direction of the bolt.

Definition of bolt dimensions.
Definition of bolt dimensions.
Nodes used for the positioning of the bolt.
Nodes used for the positioning of the bolt.
Definition of several bolts using a table

Definition and positioning of 10 bolts using a TABLE. All bolts point in negative $z$-direction. The upper washers are positioned on the upper tool surface at $z=0.052$.
