Effective Estimations of Transient Vibrations in Mechanical Systems

The complex behavior of mechanical systems of unsteady regimes, leading to increased energy consumption and sometimes to a failure, requires a more careful analysis of their work under these conditions, especially when actions are random. The reasons for increased energy consumption and failures in these systems are outputs of system parameters over the permissible level due to the specific features of transients. To address emerging problems the possibility of transient analysis in mechanical systems under the influence of random loads is considered. Given methods allow obtaining an approximate estimation of systems parameters and therefore to make a conclusions on their reliability. According to the presented methods the concrete transients parameters of mechanical systems were obtained that is often not possible using the direct methods of calculation. Thus, the paper shows the opportunity to estimate transients, even in those cases where the use of direct methods for the study of processes in a complex mechanical system is very difficult.
