Abstract


The tribological study has important social and economic significance , the friction and wear is a very complex lasted process . In accordance with the classic theory of friction and wear , the friction velocity of the change does not cause much changes in the frictional force , so usually the study , are generally ignored count changes in friction velocity impact on friction . Despite the friction velocity change of friction is very small , but continuous , periodic variation of the friction velocity may lead to a worsening of the conditions of friction , such friction conditions change continuously accumulated , leading to some type of failure of the friction pairs , such as fatigue wear . Tribological studies important means is the friction test, in order to study the friction phenomena , developed a wide variety of friction test system . In these friction test system can not be achieved the friction velocity changed in real time test , in order to verify the friction velocity change of friction wear , as well as to study the cyclical fluctuations in the performance and characteristics of the friction material friction velocity change from exploring non- the idea of a uniform friction and wear processes proposed to build a non- uniform friction and wear testing device . Taking into account the experimental system should have the basic functions , the use of machinery, electronics and automation control technology to complete the design of the overall program , and to solve the related hardware and software in the design and production of a range of issues , and build the entire non- uniform state friction test system . Non- uniform friction and wear testing system commissioning test results show that the system has achieved the desired design objectives and functions , and found similar conditions the same friction conditions and the equivalent friction course and friction work , in a state of non - uniform friction sample the greater amount of wear , wear more serious friction pair wear of the friction velocity change would have an impact of the envisaged initial validation .
