Diagnostic models of the states of developing fault for working parts of the excavator

摘要

The approach of designing a power transmission model (diagnoser) of the multi-bucket wheel excavator used in brown coal mining, presented in the study, helps prepare an effective method for identifying the states of developing fault. In order to develop such model/diagnoser it was necessary to measure the loads required for determination of the distribution function of the mining moment. Probabilistic methods were applied for establishing the state of initiating activities to protect against fault.
