M. To assign multilinear springs to spring supports
To model varying resistance to external loads at a spring support, use the following procedure.
You must assign spring supports to nodes before assigning multilinear spring definitions. You may not use multilinear springs in a model that contains tension-only or compression-only springs.
- Select one or more nodes assigned with spring support types.
- On the Specifications ribbon tab, select the tool in the Supports group. The Create Support dialog opens to the Multilinear Spring tab.
- In the table, type the Spring Stiffness constant which corresponds to a Displacement. These should be in order starting with the minimum displacement (e.g., this may also be the largest negative displacement) to the maximum positive displacement. All spring constants should be zero or positive values.
- Click Assign.
