More about Resulting Constraints

aremind.gif (956 bytes) DMU Kinematics Simulator lets you define and edit 17 different joint types.

The table below describes the constraint types created when using the axis mode to create the following joints:

V4 NAME
JOINT TYPE
 
RESULTING CONSTRAINT TYPES
u joint
 U Joint 
  • coincidence (between axis systems origins) 
  • angle 90deg 
    (x axis1/z axis2)

    Notice you can define 
    u joints without constraints
