| 摘要：摩擦磨损问题存在于人类物质生活的方方面面，在汽车，设备，冶金，铁路，电子，航空航天等许多方面，他无时不刻不存在我们的生活当中，与我们的生活息息相关。如果能在摩擦学方面采取正确的措施并采取积极的应对方法，便能够大大的节约能源的消耗，对能源危机也能起到缓解作用，所以我们要积极主动地去研究摩擦磨损这门科学，从中不断地总结经验规律，。越来越多的国家开始着手对摩擦磨损实验进行研究，也催生了摩擦磨损试验机的诞生，由于投入实验的先后，与技术的落后和先进的差异造成了不同国家对该实验的研究差距。目前，世界上只有北美，欧洲以及亚洲的日本等少数几个发达国家有专业多功能摩擦磨损试验机的生产企业，我国也较早跻身于摩擦磨损实验的研究，且取得了一定的成就。我国早在1964年就进行了摩擦磨损实验的研究，因为我国的石油产业和材料力学产业急需这方面的相关研究，最近的几年我国在摩擦磨损试验机的研制中也取得了一些成就，且在摩擦磨损实验的领域逐渐形成了一条完善的产业链和研发团队，所以研究本课题具有着极为重要的意义。40867 毕业论文关键词：摩擦、试验机、多功能、摩擦学 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.
