| ABSTRACT Suspension system of high mobility tracked vehicles is often fitted with torsion bars and hydraulic shock absorbers. Characteristics of these elements have a great effect on shocks and vibration resulting from drive of vehicles over irregular terrain. This study is concerned with evaluation of the stiffness of torsion bar of Armored Personnel Carrier M113 and how it can be affected by road configuration and vehicle speed. A complete test rig equipped with a complete measuring system has been designed and manufactured to measure the moment acting on torsion bar and the corresponding twist angle. The measured parameters are used to evaluate vehicle suspension characteristics. The frequency and amplitude of an arbitrary rigid terrain profile with constant vehicle speed are introduced in the test rig by adapting the rotating speed and the profile of rig driving cam. Design and simulation of the test rig were carried out by the aid of ADAMS program. | ||
