摘要：

Overload brings serious danger to a friction mine hoist and has already caused a great many accidents in coal mines. In order to seek out its diagnosis basis from a kinetic aspect, the effect that overload has upon the container-rope vibration system was investigated. Within this study steel ropes were treated as a continuous elastomer and modal analysis method based on the Ritz series was applied. The numerical calculation results were verified through the data analysis of a simulation experiment. This study shows that overload lowers the basic vibration frequency significantly and that this effect may serve as an effective diagnosis criterion to improve mine hoist safety.
