Springs—Creo Ansys Simulation
A spring idealization enables you to model the stiffness in a connection between two references in your model. Springs transfer loads between the two references. Springs can be modeled as 1D or 3D springs. One end of a spring can be grounded which means that the solver applies a fixed constraint to that end of the spring. The longitudinal or torsional stiffness properties, and spring preloads are defined as spring behavior and can be reused by multiple springs.
To Define a Spring
When defining springs you must be aware of the following points:
• The ends of a 1D spring must not overlap.
• The ends of the same spring cannot share a reference. However references can be shared with other springs.
• When using datum points as spring ends, only one end can be a datum point. The other end must reference a body. The spring end that is at a datum point must be grounded or shared with another spring or with a mass.
To define a spring perform the following steps:
1. Click > 
Spring. The Spring Connection dialog box opens.
Spring. The Spring Connection dialog box opens.2. Specify a name or use the default name. Optionally, click the color swatch adjacent to the Name box to change the color of the icon, the distribution, and the text displayed for the spring.
3. Select a surface, edge, curve, vertex, or datum point to use as the first end of the spring. Your selections appear in the End 1 reference collector.
Click 
if you want to ground End 1 of the spring. This means that this end of the spring is fixed or constrained in all directions. This action also unfixes the other end (End 2) of the spring, if it is fixed.

Your selections appear in the End 2 reference collector.

and select any alternative Cartesian coordinate system from the Model Tree or Graphics Window to designate it as the spring coordinate system.
