Joints degrees of freedom
NettetAbstract. A point has three degrees of freedom in space: to define where it is, we need three coordinates x, y and z, or r, θ and z. It can make independent movements in three directions mutually at right angles. If we connect it by a link of fixed length to a fixed point with ball joints at each end, then we remove one of its degrees of freedom. NettetThe joint model will have from one to six degrees of freedom, and both the measurement technique and the means used to describe the motion will be influenced by the model …

NettetThis constraint reduces the joint degrees of freedom to two—one translational, along the cylindrical axis, and one rotational, about the same axis. One mate constraint between two planes normal to the cylindrical axis. This constraint removes the translational degree of freedom that the first mate constraint provides between the two parts.
