| 摘要滚动直线导轨副是以滚动摩擦为主的直线导向功能部件，因其具有承载能力强、摩擦系数小、进给速度快、定位精度和重复定位精度高等优点，越来越多被高精度数控机械、自动化设备所采用。因而对其寿命测试很有必要性。 本文是针对国内滚动直线导轨副规格，测试对象是宽度为35~65mm的滚动直线导轨副，并且能够满足同时模拟三根导轨的工况跑合，加载部件能够分别控制加载三根被测导轨，根据这些要求设计的滚动直线导轨副寿命测控系统。并介绍了液压加载系统的工作原理，试验台跑合控制系统；还介绍了一些用于监测导轨寿命性能参数变化状况的传感器选型，以及对控制系统的原理电路和硬件选型的介绍等。21434 关键词： 滚动直线导轨副 寿命试验 控制系统 硬件选型 毕业论文设计说明书（论文）外文摘要 Title Design of measurement and control system of linear guide life test---The hardware system design Abstract The linear guide is a linear guide function part is mainly based on rolling friction, because of its high bearing capacity, small friction coefficient, feed speed, accuracy and repeatability of positioning accuracy, more and more high precision CNC machinery, automation equipment used. The test of the life is very necessary. This paper is aimed at the domestic linear rolling guide specification, the test object is 35~65mm width of the linear rolling guide, and can meet the simulation of three guide rails condition running, load components can respectively control loading three measured rail, according to the design requirements of the linear guide rail pair lifetime measurement and control system. And introduces the working principle of the hydraulic loading system, test bench running control system; it also introduces some changes for sensor selection condition monitoring of rail life performance parameters, as well as the principle of the circuit and the selection of hardware of the control system is introduced.
