Abstract

In order to solve the problem of realization of the manual slack adjuster’s life test system, this paper introduces the hardware system design and software programming to control the movement of manual slack adjuster intelligently, so as to record and judge single manual slack adjuster’s life. The paper firstly introduces the manual adjuster’s structure, work theory and the structure expression of its failure. Then, based on the work theory, it is designed that the test system which mainly consists of hardware system and software system. The hardware system is composed of computer, PLC (Programmable Logic Controller), electric control system, pneumatic system, sensor system, the adjuster to be measured and so on. The software system consists of control software and display software. Control software is designed by using ladder diagram for programming in CX-Programmer 7.3 environment. Meanwhile, display software which is based on MCGS (Monitor and Control Generated System) software is designed with a reasonable and convenient interface. We calculate uncertainty in life testing of the manual slack adjuster to analyze the experimental results. The experimental results show that the system runs stably and measures accurately. Consequently, it meets the design requirements well.
