The test system was developed for high-frequency fretting conditions (2000Hz) by using electro dynamic shaker. Contact resistance, normal load force, friction force, and dynamic fretting displacement were recorded explicitly. The effect of high frequency vibration on fretting wear of Au-plated electrical contact is studied. Comparison between low fretting frequency (10Hz/50um) and high frequency (2000Hz/0.4um;1500Hz/0.4um) indicates that higher velocity amplitude of fretting result in increasing electrical contact degradation. Surface characteristics of fretted area are also analyzed by SEM, and friction force feature under different vibration frequency are also discussed. It is clearly revealed that the fretting frequency is an important factor for electrical contact degradation and the failure mechanisms of contacts under low and high fretting frequency are different. |
