Summary:

The dynamics of the vehicle is strongly dependent from the quality and interaction between its subsystems. The quality of assembly and mounting of bearings can effect the characteristics of the system, especially its dynamical properties.The assembly process of bearing joints requires rather high pressing forces. At the same time the accuracy of the assembled components must be controlled with extreme precision. Rather small deviations from the predefined limits can cause quite severe complications, - such as necessity of maintenance, or just problems with dynamical response of the subsystem, especially under heavier dynamic loads.The goal of the study was to evaluate the status of bearing joints assembly, and to optimize the process of mechanical integration. The control of the mounting forces was altered introducing the high frequency vibration excitation. The resulting effect decreased friction and static load forces in the joint under the assembly.Experimental investigations of the system were based on laser holographic interferometry, enabling effective visualization of dynamic processes taking place in the assembled system. The optical measurement scheme had to be adopted to the complex set-up of the experiment. Numerical analysis of the mathematical model of the system enabled to optimize the parameters of the excitation and to produce best results in the sense of dynamical characteristics of the system
