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.
Keywords ：the linear rolling guide life test Control system the selection of hardware
