MK7-3型拦阻装置缓冲系统动力学分析

摘要

The operation principle of the MK7-3 arresting gear is analyzed, the dynamic model of the damper sheave and the cable anchor damper is established by Newton's law. It is found that the damper sheave can effectively reduce peak cable tension. And the cable anchor damper can reduce the slack between the crosshead assembly and fixed sheave assembly of the arresting engine and effectively prevent the cable vibration.%分析了MK7-3型拦阻装置的工作原理,采用牛顿定律建立了滑轮缓冲装置和钢索末端缓冲装置的动力学模型.研究发现,滑轮缓冲装置可以有效地减小阻拦初期发生的钢索张力峰值;钢索末端缓冲系统可以减小动滑轮组和定滑轮组之间钢索的松弛,从而防止拦阻装置在阻拦过程中钢索出现颤动.
