Abstract:
In the paper there is presented a procedure for the life testing of a hinge pivot in a dump car. This unit is one of the most significant elements in the design on which depends traffic safety. As a method for the estimate of reliability and life of the element under consideration there are chosen accelerated life tests allowing the definition of fatigue strength characteristics using a limited number of samples at the specified forced mode. Particular attention is paid to the circuit of sample installation on a plant, to the circuit of loading, to the estimate and substantiation of load values at the known loading range of the hinge pivot unit corresponding to speed motion distribution of a car under operation. The analysis of acting loads in operation is carried out, a total damaging impact during car operation and an equivalent force of sample loading are defined identical by a damaging impact to an acting loading range of a sample under testing are defined. According to the investigation results there is developed and approbated successfully a new procedure for the fulfillment of bench tests allowing more complete and reliable estimates of hinge pivot unit life for a dump car in comparison with computational methods.
