The “General support” allows the definition of constraints between a shaft and the housing or between two shafts for all six degrees of freedom independently.
First a selection can be done to which element the shaft is connected to. It can be the housing or a second shaft.
For each degree of freedom, a type of constraint can be defined then:
•No constraint: No constraint in the direction is defined.
•Fixed: The degree of freedom between both elements is coupled in both positive and negative direction. An offset or a clearance can be defined optionally. A positive value for the offset results in a movement of the current shaft in this direction, or a force on the selected shaft in this direction. The clearance is either zero or a positive value, it may not be negative.
•Fixed to the left (or right): The selection “Fixed to the left” means than the selected shaft is constrained only in the negative direction (left on a horizontal axis). “Fixed to the right” is the constraint in positive direction only. For the unidirectional constraint an offset can be defined.
•Stiffness: The “Stiffness” acts like a spring. An offset and a clearance can be defined. Offset and clearance are defined as explained for ‘Fixed’ above.
•Stiffness to the left (or right): Like the rigid constraint also stiffness can be defined in just one direction. The stiffness and an offset can be defined.
