Simulation and Field Measurements of Reliability Parameters of Dump Truck Hydraulic System

Abstract

Paper studies the problem of non-failure operation of dump trucks hydraulic system that is exploited in the climatic conditions of Kuzbass region. The main characteristic of the Kuzbass climate is hardly continental, so, it has sharp fluctuations in ambient temperature for seasons, for a month or even a day. To analyze the negative factors affecting the operation of the dump trucks hydraulic system a systematic approach was used, based on the methodology of SADT structural analysis. The result of field and cameral researches identified that the major negative factor is instability of kinematic viscosity of working fluids used in the hydraulic system of mining dump trucks over a wide range of ambient temperatures. There were offered the further ways for methods to stabilize the parameters of working fluids in the hydraulic system of dump trucks.
