【Abstract】 This paper investigated the influence of performance of friction material on properties of ultrasonic motor(USM).Three kinds of friction material of USM with different fiber orientation were developed.Test research was carried out on a simulated tester of USM.Effects of anisotropy of friction material on properties of USM were discussed.The action of fiber orientation of friction material were studied.These results showed that the friction material with high elastic modulus and fiber orientation paralleling with sliding direction is beneficial to improvement of USM performance.更多还原
