Simultaneous Collisions in Connected Bodies Systems
Abstract
Collision of bodies often occurs in robots or in manipulators, in assembling or in control of machines, in vibration processes or in vibrodrivers [1,2]. Impact takes place when two bodies collide with each other causing relatively large contact forces between bodies in a very small interval of time. During this time interval no notable position changes occur to the body. Velocities and angular velocities, on the other hand, can change significantly during the impact. In this paper all unknowns are determined by using these approaches according to the main principles of theoretical mechanics - impulse and momentum [3,4]. The collision in connected bodies systems in the plane and rectilinear motion is described. The impact process at simultaneously more than one point is studied.
