The paper presents the structure and mathematical model of a prospective test and measurement exercise bench for development and evaluation of performance of special equipment of fast cars. The mathematical model of the stand includes a car dynamic model when driving on uneven terrain, and a model of the vibrational platform of the stand. The use of the model allows to adequately identify the driving power of a real stand.

The article describes a method of determining power requirement for drives of prospective test and measurement exercise bench in order to develop and evaluate performance of special equipment in fast cars. The method is based on mathematical modeling of machine dynamics when driving on uneven terrain and simulation of body movements obtained in the model of vibrational stand platform. With the proposed method it was possible to determine the capacity of drives to simulate the dynamics of the housing for a high-speed track-type vehicle.

The article describes a new analytical dependence for definition of average speed of rectilinear motion of a caterpillar with restrictions on cushioning system. The peculiarity of this dependence consists in taqking into account the hyperbolic sector of speed ability. It is shown that formula usage allows to receive a more authentic estimation of the average speed of a caterpillar, which is especially important for definition of loading and durability of suspension members elements.

In article the algorithm of management by a corner of folding of sections articulated tracked vehicle which use raises smoothness of a course of the car at the expense of decrease in amplitudes of longitudinal-angular fluctuations section is presented.
