Specifying a value of one would result in a perfectly elastic condition. The restitution coefficient was set to zero to specify an inelastic collision. This can be done by either specifying impact parameters or a restitution coefficient. The material selection was not used for this condition and the elastic properties were manually defined. The other contact condition is defined between the bullet and pendulum. Specifying a steel-rubber condition is the same as a rubber-steel condition. If the material conditions were specified differently, the order of selection does not influence the definition. The material condition is used to automatically specify the friction and elastic properties of the collision. One contact condition groups the barrel, firing disk, and bullet into one definition using a вЂњSteel (Dry)вЂќ material condition for each selection. There are two contact conditions defined. The bullet velocity can be adjusted by modifying the spring constant.

This is done by specifying the free length of the spring to be larger than the specified distance between the firing disk and barrel in the model. It is set up using a compressive preload. Gravity is applied in the vertical direction.ДЄ preloaded spring connecting the firing disk to the barrel is used to set the bullet into motion. The pendulum system includes a pendulum rigidly mounted to an arm with the other end of the arm connected to a bracket allowing for only rotational movement. The example used consists of a simplified firing mechanism that includes a barrel, a firing disk, and a 9mm bullet. SOLIDWORKS Motion will not allow for bodies to stick together after impact, but an inelastic collision with the absence of this behavior can be specified in a contact condition setup. The premise of an inelastic collision is that the objects will stick together after impact, in the case of a ballistic pendulum mechanism where a bullet will penetrate into a pendulumвЂ™s body. The measured height of the pendulumвЂ™s center of mass after projectile impact can be used to calculate the velocity of the pendulum based on its gravitational potential energy and then its momentum. The ballistic pendulum mechanism includes two separate mechanical systems, the firing mechanism, and the pendulum system. It is based on a dissipative collision where conservation of momentum is conserved, but conservation of energy cannot be invoked due to the conversion of kinetic energy into inaccessible forms such as internal energy. A ballistic pendulum is used to measure a projectileвЂ™s momentum, from which it is possible to calculate velocity and kinetic energy.

Motion can be applied to the mechanical system through motors, forces, gravity, or preloaded springs. Contact conditions, springs, and dampers can be created to help define the mechanisms of operational movements. SOLIDWORKS Motion uses assembly mates to limit the degrees of freedom of a mechanical system and specify its range of movement. The first step is to set up a motion analysis to simulate the operational movements of a mechanism. SOLIDWORKS Motion: A Tip for Handling Performance 'Hogs'

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. Multiple scenarios can be set up in a single interface to analyze the behavior of a mechanism under various loading conditions. SOLIDWORKS 2012 introduced the capability of linking motion studies to a SOLIDWORKS Design Study. These outputs include displacements, velocities, accelerations, forces, etc. 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. , allows for evaluating the mechanical performance of a rigid body mechanism through simulating its operational movements.
