MV-2110: Use an NLFE Helical Spring in a Cam-Follower Mechanism
In this tutorial, you will lean how to use a pre-defined NLFE Helical Spring sub-system component in a model.
- What Are NLFE Components in MotionView?
- You can add NLFE bodies in MotionView version
14.0 (onwards) using the traditional Body icon in toolbars or through the
browser. In addition to this, ready-to-use subsystems or Components have
been provided. These are components (MotionView
system definition) that can be added to the model using very few user inputs
such as, for example for a Helical Spring: wire diameter, coil diameter,
material properties, number of coils, etc. MotionView will automatically create the building
block entities (such as points, bodies, and joints) and standard outputs
needed to represent such a subsystem.The following components are made available:
- Helical Spring
- Stabilizer Bar
- Belt-Pulley
- Why Use an NLFE Spring?
- An NLFE sub-system offers the following advantages:
- The spring component is added as a body, which means the mass and inertia of the spring is included in the model.
- The dynamics induced by the mass of the spring can be modeled and simulated (for example, surge in springs).
- If the deformations in the model are likely to go beyond the linear assumptions, NLFE will account for it.
- Stress strain and deformation contours can be visualized.
- Coil-to-coil clash is modeled automatically.
Review the Model
In this step, you will review the provided cam follower model.
Add an NLFE Helical Spring
In this step, you will replace the coil spring with an NLFE Helical spring component.
Solve and Post-Process the Model
In this step, you will solve the model and plot the results.
Compare Results
Now you will compare the results from the NLFE spring and the regular spring.
