Rocker Arm Force Analysis of Crown-Block Heave Compensation System Based on ADAMS

Abstract:

This paper compares three common installation ways of swing arm and carries out simulation analysis by using Adams software. The research results show that when using intercrossed enwinding wirerope, the swing arm will bear alternating load and the load variation range is huge, load G’ will change obviously and bring great impact on system control precision. When using along enwinding wirerope, the swing arm’s load is slightly bigger than wirerope tension and the load variation range is very small, load G’ will be static and it’s easy to get high control precision. By reducing the length of lower swing arm, increasing the length of upper swing arm and the offset distance, its working condition can be improved when using intercrossed enwinding wirerope.
