| 摘 要： | 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。

Finite Element Simulation of Deformation of Steel Belt of Overwind Protection for Vertical Shaft Lifting |
| |
| Abstract: | Steel belt of buffer structure with plastic deformation,employed in vertical shaft lifting as a overwind protection device,is simple and of convenient maintenance.Steel strip bends large deformation and wear when passing through buffer structure,which will damage the buffer strip,and reduce its initial strength as well.This paper focuses on the influence of steel strip thickness and pressure roller diameter on the deformation of steel belt by applying the finite element simulation,to provide theoretical basis for reliability design of the steel strip. |
