Dynamic modeling of a part mating problem: threaded fastener insertion

A dynamic simulation of threaded insertion is developed based on Euler's equations, impulsive forces, and a geometric description for threaded parts. Points of contact between the threaded parts are determined and tracked during the simulation. Reaction forces are computed based by the kinematic description. The simulation is used to investigate the behavior of a bolt during insertion into a nut under grasp stiffness and damper control.<
