Abstract：Friction and wear problems exist in the material life of mankind, in the automobile, equipment, metallurgy, railway, electronic, aerospace and so on many aspects, he no moment does not exist in our life, and our life are closely related. If in tribological aspects to take correct measures and adopt positive coping methods, can greatly save energy consumption, the energy crisis can also play a role in mitigation, so we should actively take the initiative to study the science of friction and wear, the constant summary experience rules. More and more countries start and begin to study on the friction and wear experiment, also gave birth to the friction and wear testing machine was born, due to experimental investment successively, backward and advanced differences and technology caused the different countries of the research gaps. At present, in the world only to North America, a few developed countries, Europe and Asia, Japan have professional multi-functional friction and wear testing machine of production enterprises, China's earlier among the in friction and wear experiment research and has made some achievements. China's early in 1964 were friction and wear experiment research, because of the development of China's oil industry and mechanics of materials industry in urgent need of the related research, the recent years our country in the friction wear testing machine also made some achievements and gradually has formed a complete industrial chain and R & D team on the friction and wear experiments in the field. Therefore, the research on this topic has a very important significance.
Key words：friction, testing machine, multi-function, tribology
