摘   要

 摩擦、磨損和潤(rùn)滑在機(jī)械設(shè)計(jì)中占有重要的地位，特別是現(xiàn)代機(jī)械產(chǎn)品在向高速、高精度大批量和生產(chǎn)過(guò)程高度自動(dòng)化、連續(xù)化的方向發(fā)展過(guò)程中，機(jī)械設(shè)計(jì)，如果不考慮摩擦、磨損和潤(rùn)滑問(wèn)題，就不可能設(shè)計(jì)出符合要求的好的機(jī)械產(chǎn)品。也就是說(shuō)，對(duì)于現(xiàn)代的機(jī)械產(chǎn)品，在其設(shè)計(jì)階段就應(yīng)該把控制摩擦和防止磨損的一切因素都盡量考慮進(jìn)去，并應(yīng)用摩擦和磨損的有關(guān)理論知識(shí)和抗磨技術(shù)去指導(dǎo)設(shè)計(jì)、制造、運(yùn)行和維修，以解決機(jī)械設(shè)計(jì)中的有關(guān)問(wèn)題。摩擦系數(shù)工作在滑動(dòng)摩擦狀態(tài)下質(zhì)量特性的關(guān)鍵性指標(biāo)。針對(duì)測(cè)試環(huán)境要求，研究設(shè)計(jì)了一種新型摩擦系數(shù)高精度測(cè)試儀。討論了摩擦系數(shù)測(cè)試的原理與方法，設(shè)計(jì)了摩擦系數(shù)測(cè)試臺(tái)的基本結(jié)構(gòu)，研究了力傳感器的工程實(shí)現(xiàn)步驟。整個(gè)測(cè)試儀的綜合測(cè)試準(zhǔn)確度優(yōu)于5%。

The Design and Implementation of Ring Coefficient of Friction Tester
 
Abstract

 Friction, wear and lubrication play an important role in mechanical design, especially in modern machinery to high-speed, high-precision，high-volume and highly automated production process, direction of continuous development. In mechanical design, if you do not consider the friction , wear and lubrication problems. We can not design good mechanical products which meet the requirements of good mechanical products. That is, for modern machinery, in its design phase should be controlled to prevent friction and wear as much as possible all the factors should be taken into account, and apply the friction and wear of the theoretical knowledge and the wear technology to guide the design, manufacture, operation and maintenance, to address issues related to machine design.  The key indicators of quality characteristics for coefficient of friction that work in the sliding friction.
 Direct to the requirements for environmental testing. We research and design a new high-precision coefficient of friction tester. Discussed the principle and method of coefficient of friction testing, designed the basic structure of the coefficient of friction testing bench, researched the implement steps of the force sensor project. The tester’s comprehensive testing accuracy is better than 5%.
