摘要
介绍了井下车辆液压系统动态性能的计算机辅助测试系统,该测试系统基于LabVIEW软件平台,通过控制数据采集卡,可同时采集多路电信号,并能灵活消除测试系统的零点误差,具有测试数据存储、滤波以及实时显示等多种功能,是一种功能完备的虚拟仪器。利用该测试系统,对JY-5型多功能服务车液压系统动态压力进行测试,获得服务车转向、制动液压系统压力的动态变化数据。通过分析压力变化曲线,总结出多功能服务车转向、制动液压系统的动态特性。研究成果肯定了当前液压系统的合理性,提出井下车辆动态性能研究的新方法。分析结果对JY-5系列多功能服务车性能的改进提供了重要的参考依据。
The theory and composition of a computeraided measurement system, by which the dynamic characteristics of hydraulic system of underground vehicle can be measured,is introduced in this paperBased on Lab VIEW,the measurement system can acquire multiple electrical signals through dataacquiring boardThe measurement system is a VI(Virtual Instrument)which has many functionsThe zeroerror of the system can be eliminated conveniently,and testing data can be stored,filtrated,and viewed in real timeThe dynamic pressure of the hydraulic system of JY5 multifunction underground vehicle is measured with the measurement system,and the dynamic characteristics of the hydraulic system are summarized by means of analysisThe rationality of the hydraulic system of the vehicle is verified,and a new method to study the dynamic characteristics of underground vehicle is put forwardThe study result is valuable to improve the characteristics of JY5 truck
