“…Due to the good mathematical properties of the Wiener process, which has long been widely used in equipment reliability prediction and life analysis [25][26][27]. However, there are fewer research methods on the life of ultrasonic motors, One of the earliest examples of life research on ultrasonic motors is Takaaki Ishii et al [29] who explored the output characteristics and life of linear motors in relation to the friction material on the sliding surface to obtain a life prediction model; Xiu Tian et al [30] developed a life prediction model for the friction material of traveling wave ultrasonic motor based on the friction mechanism between stator and rotor; Lin Yang et al [31] predicted the performance degradation trend of traveling wave motors based on a machine-learning to obtain the RUL of the motor. The above research provides solutions for predicting the RUL of ultrasonic motors based on model-based and machine-learning respectively.…”

In this paper, the useful life prediction of traveling wave ultrasonic motor is taken as the research object to explore the estimation method of motor life and analyze the main mechanisms affecting the life of motors. The degradation pattern of motor performance is stochastic and nonlinear, and two modes of remaining useful life prediction models were established based on Wiener process theory. The parameters of the model were estimated based on Maximum Likelihood Estimation and multidimensional search optimization method. The performance of each degradation model was evaluated by introducing Akai Information Criterion and error evaluation method. Through the construction of an ultrasonic motor life test system and the life test, experimental data that can reflect the degradation of motor performance were obtained. The feasibility of the proposed method was verified using simulated signals and experimental datasets of motors. Compared with the existing methods on remaining useful life prediction, the modeling approach proposed has its uniqueness and superiority.

“…In recent years, research on friction of ultrasonic motor has mainly focused on the frictional property of the contact interface, [1][2][3][4] the wear principle of friction material, [5][6][7][8] and the life forecasting of ultrasonic motor and friction material. [9][10][11][12] However, the influences on ultrasonic motor performance and contact interface by wear of the friction material are seldom researched. In order to promote the rapid development of ultrasonic motor, this aspect needs to be researched.…”

Friction material is one of the key components in an ultrasonic motor. The wear of the material affects the contact friction and output performance of the motor. A method which utilizes the equivalent wear of friction material to simulate the wear during operation is proposed based on the wear characteristics of the ultrasonic motor's contact interface. A relationship between wear and performances of the ultrasonic motor is constructed. The influences of wear on output performance, friction coefficient of the contact interface, and wear morphology are researched in the experiments. According to the experiment's results, with wear of friction material (decreasing thickness), the output performance of the ultrasonic motor presents a downward trend, the friction coefficient between contact interfaces decreases gradually, the friction-reducing ratio between contact interfaces increases gradually, and the wear between contact interfaces decreases. The results are helpful to understand operating performance, design, and select friction material of ultrasonic motor.
