Abstract

The aim of the work is to propose methodology applied for investigation of central inertia moments and gravity center of large volume and weight bodies, e.g. rail vehicles. The methodology is applicable for various large dimensions of bodies and high weight machines. Two mode of the designed methodology is presented one with the direct support of the body frame and second utilizes the additional weight represented by additional frame substituting the wheel set. The result of the experiment processed by proposed methodology is determined inertia effect within arbitrary axes. These results are useful for investigation of the movement dynamic stability and design construction optimization of rail and road vehicles. The proposed methodology is based on the known fact that the inertia moment could be obtained from oscillation period of vibratory movement body which is embedded on the rigid and elastic supports. The position of the gravity center is determined by derived equations based upon the mode of proposed of methodology.
