SOLIDWORKS Motion Utilizing Design Studies to Evaluate What-If Scenarios SOLIDWORKS Motion included in SOLIDWORKS Premium allows for evaluating the mechanical performance of a rigid body mechanism through simulating its operational movements. It allows for simulating the effect of forces, springs, dampers, gravity, component contacts and bushings to effectively visualize and measure the kinematic and dynamic behavior of a system. These outputs include displacements, velocities, accelerations, forces, etc. SOLIDWORKS 2012 introduced the capability of linking motion studies to a SOLIDWORKS Design Study. Multiple scenarios can be setup in a single interface to analyze the behavior of a mechanism under various loading conditions. This guide will make use of a ballistic pendulum mechanism to cover the steps of how to create a design study linked to a motion study. SOLIDWORKS Motion Setup The first step is to setup a motion analysis to simulate the operational movements of a mechanism. SOLIDWORKS Motion uses assembly mates to limit the degrees of freedom of a mechanical system and specify its range of movement. Contact conditions, springs, and dampers can be created to help define the mechanisms operational movements. Motion can be applied to the mechanical system through motors, forces, gravity or preloaded springs. A ballistic pendulum is used to measure a projectile’s momentum, from w hich it is possible to calculate velocity and kinetic energy. It is based on a dissipative collision where conservation of momentum is conserved, but conservation of energy cannot be invoked due to conversion of kinetic energy into inaccessible forms such as internal energy.
