Individual links of a kinematic chain are often interconnected by elastic or damping (or both) elements. Among these are mainly: springs, dampers, absorbers, actuators. Components expressing the potential energy accumulated in such elements and its dissipation need to be introduced to the system’s equations of motion. The present chapter discusses a method of modelling spring-damping elements treated as massless objects. Constraint equations occurring when kinematic subchains are joined in certain systems are also presented.
