Abstract

The methods of dynamic testing of cars in laboratories for optimization research of cars in special controlled conditions at rolling stands were considered. The problems, which are solved with the help of rolling stands, include the fundamental research of the creep theory in the “wheel-rail” system; studying of derailment; modeling of curve passing; decreasing of noise and vibration in the “wheel-rail” system; optimization of braking and acceleration. In order to get reliable results, the rolling stock should be in operative condition. Testing stands RVTU are used to find the actual critical speed, including the roughness of the track. The appropriateness of rolling stand construction is proved, as it allows to carry out strength, static, dynamic, vibratory, fatigue and climate tests and to check the calculating methods of mathematical modeling of cars behaviour. The rolling stands will allow increasing the reliability of results and creating the competitive products of rail transport.
