Comprehensive Joint & Force Elements

ANSYS Rigid Dynamics software supports a complete set of joint types to connect both flexible and rigid bodies. A joint is an idealized constraint on the relative movement between two bodies. Standard joint types include:

  • Revolute
  • Cylindrical
  • Translational
  • Slot
  • Universal
  • Spherical
  • Planar

Most joint types support optional “stops” that restrict the joint’s relative degree(s) of freedom within a specified range. The software also supports a general joint type, which provides selective restriction of relative degrees of freedom. For more complex constraints, a unique constraint editor is available that allows definition of custom constraint equations.

Beyond kinematic constraints, bodies can be connected with bushings and springs whose stiffness and damping characteristics can be expressed with constants, expressions or tabular data. Force, moment and fixed displacement conditions are also available and can vary as a function of time. All joint and force elements are persistent to geometric variations and can be parameterized.
