Gavrilov S. Creation and implementation of vibration diagnostics gear motor-wheel dump trucks BelAZ

The object of research, is the vibration processes accompanying functioning of RMW of a dump truck "BelAZ". Research objective is creation and introductions of system of diagnosing of RMW of BelAZ dump trucks in vibration parameters that allows to increase efficiency of their use due to maintenance on an actual state. The main method of theoretical researches is mathematical modeling of vibration and vibration rationing. Natural tests, measurements and the spectral analysis of vibration. For the first time the method of synchronous accumulation of amplitudes of vibrations which allows to consider non-stationary operating modes of transmission knots of the car when diagnosing and to allocate levels of vibrations of tooth gearings and bearing knots on everyone to a shaft is developed. Gained further development methods of rationing of initial and limit values of the RMW diagnostic vibration parameters of a dump truck "BelAZ". Vibration norms of an assessment of initial and limit technical condition of RMW of a career dump truck "BelAZ" are developed. The onboard system of vibration control of technical condition of RMW of dump trucks "BelAZ" which allows to warn in due time a preaccident condition in the conditions of their operation is created. Use of onboard system of vibration diagnostics will provide increase of operational reliability of dump trucks.
