Abstract
Constraint force algorithms for static and dynamic analysis allow for a tremendous amount of flexibility in motion analysis. This algorithm, partly developed by dynamicists at MSC. Software, is referred to as the Constraint Force Algorithm, and has several advantages over other popular methods for formulating equations of motion. For example, ・Constraint force algorithms simulate systems with varying degrees of freedom. ・Constraint force algorithms simulate systems with static and kinetic Coulomb Friction. ・Constraint force algorithms handle collisions in a seamless fashion. ・Constraint force algorithms allow the user to specify various motions through length, velocity, and acceleration actuators. ・Constraint force algorithms deal with inequality constraints such as rope and separators.
