基于Recurdyn的可变径攀登平台的最大受力仿真与分析

Simulation and Analysis of the Maximum Force of Adjustable Climbing Platform Based on Recurdyn

风塔塔筒表面不平的缺陷是造成攀爬平台受力畸变的主要原因。受力畸变的情况下,如何找到最大受力成为难题,如果不能解决这个问题后续结构分析将无法进行。针对此问题,对设计的一种可变径风塔攀登平台进行了多体动力学仿真,对所有可能受力的情况进行了分析,并进行了排列组合和必要的推论,最后用Recurdyn对推论加以仿真验证,得出了攀登平台桁架之间受力最大的情况,分析出了最大节点受力值。分析的过程和结果给进行类似分析的学者提供了参考。

The uneven surface defect is caused by wind tower tube climbing platform by force the main reason for the distortion. When the force distorted,how to find the maximum stress becomes a problem. For this problem,the design of a wind tower can be adjustable climbing platform for multi-body dynamics simulation of all possible forces were analyzed,and the permutations and necessary inferences,and finally to the inference Recurdyn to simulation,force value obtained by the maximum force the situation,analyze the maximum node between the truss by climbing platform. The results were similar to the analysis of scholars to provide a reference.
