Joint Limits

Joint limits, also referred to as mate limits, are mapped SolidWorks distance/angle constraints. These mates restrict the movement of a joint to a specific range (for example, an arm is restricted to rotate only between 10 and 70 degrees).

Example.

The following are the distance joint limit types:

• Plane - plane

• Plane - line

• Plane - point

• Line - line

• Line - point

• Point - point

• Cone - cone

The following are the angle joint limit types:

• Plane - plane

• Line - line

Sensor Function

To monitor the angle or distance limit, COSMOSMotion internally creates a sensor to check if the limit is exceeded during a solve.

Sensor values are monitored at each output frame. If a sensor ends the simulation, the solver will step back to the last frame before that sensor value was exceeded.
