Evaluation Techniques for Residual in-Use Utility of the Railway Car Hopper-Batcher Bearing Structure with a Long-term Service

Evaluation technique for residual in-use utility of hopper-batcher bearing construction with a long-term operational life is given. The technique consists of seven steps including establishing actual technical state of the car by means of visual and ultrasound diagnostics; carrying out virtual and actual tests construction in accordance with normative documents; determining residual in-use utility on the basis of the results obtained. The necessity of determining actual physical-mechanical of bearing construction metal after long-term service is stressed in order to establish further operating life of a car.
