Impact Motion

The impact phenomenon may be used for task-oriented changing of rigid body motion. When moving body encounters with some obstacle all parameters of motion are changing as a result of impact and trajectory and type of motion are also changing. In this work the conversion of translatory motion of prismatic rigid body into plane or rotation and conversion of plane motion of cylindrical body due to impact are considered. The conditions of conversion of one type of motion into another and parameters post-impact motion are studied. Problems are solved in the framework of rigid body motion, using rigid body impact theory. Studying of such phenomena is important for location of parts on industrial conveyors, feeders, etc.

Impact Motion

This study presents the results of both a computer simulation of a vehicle crash into a rigid barrier obtained with V-SIM4 software and an experimental crash test published by ADAC (Allgemeiner Deutscher Automobil-Club). The results were obtained using the same initial conditions, which provides an opportunity to compare results and evaluate the reliability of simulation results. Observed errors and adopted models are discussed. The sensitivity of the post-impact motion to the overlap and engaged gear was studied, which is a result of non-linear phenomena occurring during the crashes. Expert witnesses (accident reconstructionists) often face such problems. Consequently, the important factor of any accident reconstruction is the knowledge of the expert and the identification of pre-impact conditions, which are uncertain. This study also addresses practical issues related to traffic collision reconstruction, employment of CCTV (closed-circuit television) in crash reconstruction, and directions in which software should be improved. The following results are useful for collision experts.
