2D contact joint properties

Sets properties for 2D contact joints These joints are not permanent and do not penetrate.

Before adding a 2D joint, be sure that the profiles or edges used for input have their normals point away from the joint and there is no penetration of one edge or profile with the other.

2D Contact Joints are not compatible with Unknown force computation. It is recommended that 2D Contact joints be suppressed before starting a simulation having an Unknown force.

Note: For 2D Contact joints, Part 2 can only have planar motion degrees of freedom with respect to Part 1.

Access:

In the Dynamic Simulation browser, right-click a 2D contact joint, and select Properties.

Suppress joint	Excludes the joint from all calculations. By default, the joint is active and included in all calculations.
	Changes the direction of the normal to the parent component .
	Changes the direction of the normal to the child component .
Parameters
restitution	Indicates how the normal velocity between the two components changes during the shock. Restitution is the ratio of the normal velocity between the two components after contact to the normal velocity before contact. (Because it is a ratio, restitution has no units.) The value of restitution is always from 0 through 1. The collision is perfectly elastic when restitution equals 1 and inelastic (that is, with no normal rebound) when restitution equals 0. By default, the restitution coefficient is .8.
Friction	Sets the coefficient of friction . This value can be from 0 through 2. The maximum boundary equals 2 to allow modeling some specific cases where physical effects (heat, moisture, age, and so on) are added in the coefficient of friction.
(More)	Displays additional properties.
Display force	Sets parameters for display of the selected force vectors in the graphics window. Available force vectors are: Action which is the force exerted by the parent component on the child component. Reaction which is the force exerted by the child component on the parent component. Normal which is the normal vector component of the force. Tangential which is the tangential vector component of the force. Resulting which is the total force (the normal vector component plus the tangential vector component).
Scale	Sets the scale of the graphics display of the type of force vector on the left. Use this option to make all of the vector visible. The default is 0.01.
Color	Opens the Microsoft Colors window so you can select the color of the type of force vector on the far left.
