【摘要】 摩擦学是研究作相对运动的相互作用的表面间摩擦行为对机械系统作用的理论和实践的科学。先进的摩擦磨损试验机及摩擦学试验技术对于摩擦学研究的深入开展有着重要意义,随着计算机技术、自动化技术以及智能控制技术的日益发展,将其应用于摩擦磨损试验系统已成为摩擦学实验测试技术开发研究的重要内容。本文所研制的往复式摩擦磨损试验机及其测试系统,正是将这些技术与摩擦磨损试验有机结合的产物。 本文在对摩擦磨损试验机的发展概况、分类、特点,摩擦磨损试验的目的、试验的基本方法等进行综合分析的基础上,采用设计方法学的方法对摩擦磨损试验机进行优化设计,建立了摩擦磨损试验机的要求明细表、功能结构图、设计模幅箱。从机械、测量控制、软件等方面对往复式摩擦磨损试验机进行设计,该试验机具有如下特点:(1)实现了对摩擦副的摩擦力、磨损量、摩擦系数等数据的实时采集、分析处理、数据曲线拟合、显示、存储与输出;(2)可在一定范围内实现载荷、速度、润滑的单因素控制,并可同时定性和定量显示运动中的摩擦力大小;(3)该试验装置操作简单,数据可靠,有较好的重现性。通过在该试验机上进行的一些试验证明,该试验机性能稳定,测试系统准确可靠,可有效地对摩擦副不同材质和工艺的摩擦磨损性能进行评定,以获得可靠的试验数据。本文所设计的摩擦磨损试验机在实际生产中有广泛的应用前景。更多还原

【Abstract】 Tribology is a theory and practice science, which studies the action between the relative motion interactive surfaces friction and the mechanical system function. The advanced friction abrasion testing machine and the friction study experiment technology has the vital significance regarding the friction study research thorough development, along with computer technology, the automated technology as well as intelligent control technology flourishing more and more daily, applies it in the friction wear test system has become the friction study experiment to test the technical development research the important content. This article develops the reciprocation type friction abrasion testing machine and its the test system, are precisely these technical and the friction wear test organic synthesis product.This article in to rubs the abrasion testing machine the development survey, the classification, the characteristic, the friction wear test goal, the experimental essential method and so on carries on the generalized analysis in the foundation, uses the design methodology the method to rub the abrasion testing machine to carry on the optimized design, established the friction abrasion testing machine request detailed list of specifications, the function structure drawing, has designed a mold box. From the machinery, the survey control, the software and so on three aspects carry on the design to the reciprocation type friction abrasion testing machine, this testing aircraft has the following characteristic: (1) realized to rubbed vice- data and so on friction force, wearing capacity, friction coefficient real-time gathering, analysis processing, the data curve fitting, the demonstration, the memory AND output;(2) may realize the load, the speed, the lubrication single factor control in the certain scope, and may at the same time qualitative and in the quota demonstration movement friction force size;(3) this test equipment operation simple, the data is reliable, has well reappears the nature. Through some experimental proofs which carries in this testing aircraft, this testing machine performance stable, the test system accurate is reliable, but effectively to rubs the vice-different material quality and the craft friction attrition performance carries on evaluates, by obtains the reliable tentative data. This article designs the friction abrasion testing machine has the widespread application prospect in the actual production.更多还原
