某型飞机操纵系统钢索滑轮组动摩擦特性研究

摘要

In order to study the differences of dynamic friction characteristics between domestic rope pulley and imported rope pulley in certain aircraft control system ,and provide data support and engineering reference for the improvement of rope pulley design in the control system ,based on relevant domestic and abroad paper mate-rials and engineering practice ,the dynamic friction characteristics of imported rope pulley is analyzed ,which will be adopted in this control system .Applying basic principles of classical mechanics theory ,comparative a-nalysis of dynamic friction characteristics is made for the domestic rope pulley being used ,and using Labview software and spectral analysis software the test data is processed .Result shows that the dynamic friction of im-ported rope pulley is small ,and the stiffness is large ,which meets the requirements of engineering design .It provides the reference for improvement of the control system .%为研究某型飞机操纵系统国产钢索滑轮组与进口钢索滑轮组动摩擦特性的差异，在参考国内外相关文献资料和工程实践的基础上，就该操纵系统中拟采用的进口钢索滑轮组进行动摩擦特性的研究。运用经典力学理论的基本原理，通过与系统中正在使用的国产钢索滑轮组动摩擦特性的对比分析，并对试验中取得的数据运用Labview 软件和频谱分析软件进行处理。结果表明：该进口钢索滑轮组的动摩擦力较小、刚度较大，符合工程设计的需要。研究结果为该型飞机操纵系统钢索滑轮组的设计改进提供工程依据。
