摘要: 介绍了一个基于Labview的挖掘机多路阀全电液综合测试系统。根据相关多路阀测试标准要求以及挖掘机多路阀的特点完成测试系统的液压系统原理和数据采集控制系统的设计。系统采用电液比例技术完成液压系统的控制包括系统压力、流量、多路阀的动作以及负载模拟,并利用Labview软件完成测试系统软件设计实现数据的自动采集、处理、显示以及打印等功能,因此系统具有很高的自动化程度能有效提高挖掘机多路阀的测试效率。以完成的测试系统为基础对某挖掘机多路阀进行相关的测试试验,从结果表面设计的综合测试系统功能完善、操作简单。Abstract: This paper mainly introduces an integrated electro-hydraulic testing system for excavator multi-way valve whose software is based on Labview. According to the relevant requirements of multi-way valve testing standards and the characteristics of excavator multi-way valves,the designs on the hydraulic principle of the test system,data acquisition and control system are completed. The system adopts electro-hydraulic proportional technology to implement the controls of the hydraulic system,including the system pressure,flow rate,the actions of multi-way valve and loading simulation; and the software design of the test system is completed by using Labview to realize automatic data acquisition,processing,display and print functions. The system has a high degree of automation,which can effectively improve the testing efficiency of excavator multi-way valve. To conduct relevant experiments of excavator multi-way valve based on the testing system developed,and the experiment results show that the integrated testing system designed is functional and easy operation.
