低频往复摆动式模拟平台摩擦特性及实验研究
Tribological investigation of a low-frequency reciprocating platform
摘要
Abstract
In order to overcome limitations of tribological testing techniques for MEMS micro-components, a novel micro-tribometer testing system for determining tribological properties on metal, non-metal, and polymer surfaces has been developed.Based on the operating principle of a reciprocating platform and related mathematical motion models, a variable frequency oscillating mechanism driven by an electromagnetic coil was designed to achieve recip-rocating sliding of samples and a new measuring head was applied for normal loads.Steel, glass, and PTFE against a metal ball were used arbitrarily to test the developed device repeatedly under various normal loads and oscillation frequencies.The transient friction force and friction coefficients for different friction pairs were measured.Experi-mental results show that the developed low-frequency reciprocating platform can simulate relative sliding of fretting friction under small milli-Newton normal loads.The obtained experimental results are consistent with those of other studies, which means the low-frequency reciprocating platform can stably operate and is reliable for use in research on tribological properties.关键词
