滑動(dòng)摩擦磨損試驗(yàn)機(jī)

摘  要：摩擦磨損試驗(yàn)機(jī)主要應(yīng)用于研究摩擦學(xué)產(chǎn)品的相關(guān)領(lǐng)域，目前，世界上只有美國(guó)、英國(guó)、日本等少數(shù)幾個(gè)國(guó)家有摩擦磨損試驗(yàn)機(jī)的專業(yè)生產(chǎn)企業(yè)，許多資料表明現(xiàn)有的摩擦磨損試驗(yàn)機(jī)所測(cè)試的式樣幾乎以滑塊、圓盤為主，而且可在一定范圍內(nèi)實(shí)現(xiàn)載荷、速度、潤(rùn)滑量、溫度等因素控制。而接觸導(dǎo)線式樣多以線材為主，同時(shí)要實(shí)現(xiàn)在電接觸條件下對(duì)載荷、滑動(dòng)速度、電流、電壓等單、多因素的控制。因此為了保證點(diǎn)接觸線材在這方面的研究、實(shí)驗(yàn)、開(kāi)發(fā)，研制了一臺(tái)新型、簡(jiǎn)易、性能可靠、成本較低的滑動(dòng)摩擦磨損試驗(yàn)機(jī)。

關(guān)鍵詞：試驗(yàn)機(jī)、摩擦磨損、滑動(dòng)

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 .
