You can also try to adjust the Accuracy slider in the Motion study properties to a higher level. This is the most accurate description of the bodies' surfaces, but it does require a longer time to solve. This will use an exact description of the bodies' surfaces. If the tessellated geometry description is not sufficient, check the box in the Motion study properties that says "Use Precise Contact". Increasing the resolution using this slider in the Motion study properties provides for a more accurate calculation of the contact between bodies. The density of the mesh is controlled with the 3D Contact Resolution slider in the Motion study properties.
The surfaces of the contacting bodies are meshed with triangular elements. By default, SolidWorks Motion will use tessellated geometry to represent parts that contact each other. The damping coefficient increases from zero at the beginning of impact to its maximum value when it reaches the penetration depth that you enter for this value.Īside from the settings in the Contact feature itself, there are some general settings in the Motion study that you can change to reduce the amount of penetration between parts. A typical value for Maximum Damping is 0.1%-1% of the Stiffness value.Īdditionally, reducing the Penetration value in the Elastic Properties section of the Contact PropertyManager can help to reduce the amount of penetration in the Motion study.
You can also manually enter a value for Stiffness and Maximum Damping if you uncheck the Material section of the Contact property manager. If you have assigned Acrylic, Nylon, or Rubber as the material type, changing the material to Aluminum or Steel will increase the Stiffness and Maximum Damping values. You might be able to change the material type used for the parts inside the Contact feature. This could be accomplished in a couple of ways. Specifically, you want to increase the Stiffness and Maximum Damping values assigned to the Contact feature, which are shown in the Elastic Properties section at the bottom of the Contact PropertyManager. In order to reduce the amount that the parts penetrate through each other, edit the settings of the applicable Contact feature inside the Motion study.
It is not uncommon to see parts penetrate each other like this in a Motion study. You may sometimes find that components appear to penetrate through each other when playing a SolidWorks Motion study with Solid Body Contact already defined between the components.
