Motion Analysis is required to accurately simulate and analyze the motion of an assembly while incorporating the effects of Motion Study elements (including forces, springs, dampers and friction). A Motion Analysis study combines motion study elements with mates in motion calculations. Consequently motion constraints, material properties, mass, and component contact are included in the Motion kinematic solver calculations.
A Motion Analysis study also calculates loads that can be used to define load cases for structural analyses.

Motion Analysis enables engineers to size motors/actuators, determine power consumption, layout linkages, develop cams, understand gear drives, size springs/dampers, and determine how contacting parts behave.
The result is a quantitative reduction in physical prototyping costs and reduced product development time. Motion Analysis also provides qualitative benefits such as the ability to consider more designs, risk reduction, and the availability of valuable information early in the design process.
