actuator simulation with SimScale - SimScale Update 04/2016: Elastic Support and Improved Community Support

Committed to ensuring the best experience with SimScale for our users, we are constantly improving the platform and adding new simulation features. Here are the latest updates:

Elastic Support

With the latest SimScale updates we have enabled Elastic Support, a constraint boundary condition that allows the user to add an elastic foundation to a part of a model without the need to add a domain representation such as a spring or an elastic material layer to the setup. It is defined by a stiffness parameter and reacts to tension and compression.

The application above shows the stress analysis of a pneumatic actuator consisting of a piston, a spring and an elastomer diaphragm.

The results are shown both for an analysis involving the complete assembly, as well as a second setup where the spring has been replaced by an elastic support boundary condition with the corresponding stiffness.

Using the elastic support, the mesh size and computation time have been considerably reduced, as the spring does not need to be meshed and the cyclic symmetry of the remaining assembly allows investigation of a subset of the model. The public project is available here.

The elastic support can also be used to suppress undesired rigid body motions, especially in nonlinear static analyses where inertia effects are disregarded and under-constrained systems that are likely to diverge. This can be easily accomplished by adding virtual soft springs to the setup via elastic support.

For soft stiffness parameters, the influence on the results can be often neglected. The picture below shows a metal stamping process. Here is the public project.
