滑动摩擦磨损试验机

摘  要：摩擦磨损试验机主要应用于研究摩擦学产品的相关领域，目前，世界上只有美国、英国、日本等少数几个国家有摩擦磨损试验机的专业生产企业，许多资料表明现有的摩擦磨损试验机所测试的式样几乎以滑块、圆盘为主，而且可在一定范围内实现载荷、速度、润滑量、温度等因素控制。而接触导线式样多以线材为主，同时要实现在电接触条件下对载荷、滑动速度、电流、电压等单、多因素的控制。因此为了保证点接触线材在这方面的研究、实验、开发，研制了一台新型、简易、性能可靠、成本较低的滑动摩擦磨损试验机。

Sliding friction and wear test machine

Abstract：The friction and wear test machine will be used in tribology research products related fields, at present, there is only the United States、Britain、Japan and a few countries have friction and wear test machine professional production enterprises, much of the information available shows the friction and wear test machine for testing the format almost slider, the disk-based, but in a certain range within load, speed, lubrication, temperature control and other factors. And the contact wire to wire more style, and mainly to achieve electrical contact under the conditions of the load, sliding speed, current, voltage single-and multi-factor control. Therefore, to ensure that point contact wire in the research, experiment, development, development of a novel, simple, reliable performance, lower cost of sliding friction and wear test machine.

Keywords：testing machine, friction and wear, sliding .
