立井提升过卷保护装置采用钢带塑性变形缓冲器结构简单、维修方便。钢带通过缓冲器时较大的弯曲变形及摩擦磨损,将损坏缓冲钢带,降低其初始强度。针对钢带厚度及压辊直径对变形影响进行有限元模拟,为钢带的可靠性设计提供理论基础。
Vertical shaft overhang protection device using steel plastic deformation buffer structure is simple, easy maintenance. Steel strip through the buffer when the larger bending deformation and friction and wear, will damage the buffer strip, reducing its initial strength. The effects of strip thickness and roll diameter on the deformation are simulated by finite element method, which provides the theoretical basis for the reliability design of strip.
