Activity is devoted forecasting of resonances of cermet disks frictional elements of transmissions of transport cars and to definition of ways of raise of durability. The analysis of character of collapses has allowed to put forward a hypothesis about collapse cermet owing to the high-frequency cavity oscillations oscillated by the fluid converter. The given effect is new, earlier not investigated. The method of account of natural frequencies cermet is developed for exclusion of resonant regimes. Taking into account complexity of a construction of a disk the natural frequency is analytically defined at many assumptions. For an estimation of reasonableness of the accepted assumptions at definition of natural frequencies and mode shapes cermet the method of a nondestructive check based on definition of response characteristics at sound bombarding radiation of the investigated disk - on dominating meanings of a Fourier density of process develops. Convergence of results of theoretical and experimental probes allows to predict possibility of origination of resonant regimes of operation cermet of frictional elements, it is essential to specify a technique of design account, and also to solve an inverse problem on exclusion of resonant regimes.
