Summary
An evaluation technique for the residual in-use utility of a hopper-batcher bearing construction with a long-term operational life is described in this paper. The technique consists of seven steps including establishing the technical state of the car by means of visual and ultrasound diagnostics; carrying out virtual and actual test construction in accordance with specification documents; determining residual in-use utility on the basis of the results obtained. The necessity of determining the physical-mechanical behavior of the bearing construction metal after long-term service is stressed in order to establish the further operating life of a car. The study of the chemical composition, physical mechanical properties and residual resource of the hopper-batcher bearing construction after thirty years of active service is presented.
