Joints

Components that constrain the motion between two frames

Package Contents

Assemblies
Joint aggregations for analytic loop handling
Internal
Components used for analytic solution of kinematic loops (use only if you know what you are doing)
Cylindrical
Cylindrical joint (2 degrees-of-freedom, 4 potential states)
FreeMotion
Free motion joint (6 degrees-of-freedom, 12 potential states)
GearConstraint
Ideal 3-dim. gearbox (arbitrary shaft directions)
Planar
Planar joint (3 degrees-of-freedom, 6 potential states)
Prismatic
Prismatic joint (1 translational degree-of-freedom, 2 potential states, optional axis flange)
Revolute
Revolute joint (1 rotational degree-of-freedom, 2 potential states, optional axis flange)
RevolutePlanarLoopConstraint
Revolute joint that is described by 2 positional constraints for usage in a planar loop (the ambiguous cut-force perpendicular to the loop and the ambiguous cut-torques are set arbitrarily to zero)
RollingWheel
Joint (no mass, no inertia) that describes an ideal rolling wheel (rolling on the plane z=0)
RollingWheelSet
Joint (no mass, no inertia) that describes an ideal rolling wheel set (two ideal rolling wheels connected together by an axis)
Spherical
Spherical joint (3 constraints and no potential states, or 3 degrees-of-freedom and 3 states)
SphericalSpherical
Spherical - spherical joint aggregation (1 constraint, no potential states) with an optional point mass in the middle
Universal
Universal joint (2 degrees-of-freedom, 4 potential states)
UniversalSpherical
Universal - spherical joint aggregation (1 constraint, no potential states)
