英文摘要： Artificial joint is one kind of important replacement organs in human body. It can replace the lesion or damage joint and restore the function. The friction and wear characteristics of artificial joint materials have great effect on the reliability and functionality of artificial joint. China is a country with a large population and the proportion of the elderly population is increasing. With the continuous increase of artificial joint market, the development of the friction and wear test equipment of artificial joint material, which is suit for the anatomical features and behavioral characteristics of Chinese joint during daily activities, has become very urgent. Based on the study on the existing parallel bionic hip joint test equipment, this project seeks to establish a kinematics and kinetics parameter reference database according to the Chinese typical motions during daily activities. The integrated modeling system of real mechanism of the parallel bionic hip joint test equipment will be established based on the finite element analysis method. By studying the key technologies of this parallel bionic hip joint test equipment, such as vibration control, friction compensation and stability analysis, the ability to dynamically simulate kinematics and kinetics properties of Chinese hip joint will be ensured.
