Abstract
The present invention discloses a dynamic reliability evaluation method for coupling faults of a middle trough of a scraper conveyor. Approximation precision of a moment-based saddlepoint approximation method and a function attribute of dynamic t-copula are fully utilized, and the dynamic reliability evaluation method for the coupling faults of the middle trough of the scraper conveyor is provided, so that dynamic correlation between failure modes of the middle trough of the scraper conveyor under a small sample condition is more accurately described, and accuracy of dynamic reliability evaluation of the coupling faults of the middle trough of the scraper conveyor is improved.
