伺服液压缸动摩擦力的高精度测试方法研究

Research on high-precision test methods of the dynamic friction of servo-hydraulic cylinder

动摩擦力是伺服液压缸重要性能参数,其大小反映该液压缸设计、加工制造、装配水平,同时也反映动态特性、稳定性和精度。准确、简便、快速测试动摩擦力十分重要。分析了动摩擦力机理,开发了测试软件,介绍测试流程,简述了测试系统及测试方法,并在韶关液压件厂有限公司建造的大型机架变形动摩擦力测试装置中实施,取得了良好效果。

The dynamic friction is an important parameter of sevo-hydraulic cylinder,whose value reflects the levels of hydraulic cylinders＇design,manufacture and assembly,also reflects dynamic,stability and accuracy.So it＇s very important to test dynamic frictions accurately,simply and quickly.It analyses the principle of dynamic friction,develops the test software,introduce the test process,talks the test methods of the test system simply.We have get good results by practicing the test methods in the test dynamic frictions devices of the large frame deformation which are made in Shaoguan Hydraulic Component Factory Co.,Ltd
