【摘要】 针对地铁转向架性能测试系统的需要,提出了一种基于 PXI 总线多功能数据采集卡 PX16070E 和图形化编程语言 Labview7.0的虚拟仪器构建方案。从硬件构成和软件功能上对虚拟仪器测试的功能进行了介绍。着重给出了地铁转向架纵向、横向位移动态测试方法。经实际试验表明,检测仪器具有非常高的动态跟踪精度,能准确评估地铁转向架的动态性能。更多还原

【Abstract】 Aimed at necessity of theperformance testing system in the metro bogie,a suit of virtual instrument’s constitution project based on the multifunction data collection board PXI6070E with PXI bus and the graphic programming language(Labview7.0)is provided.The testing function of virtual instrument is introduced via hardware functions and the software structures,and the testing methods of the metro bogie lengthways displacement and transverse displacement are emphasized.High dynamic tracking precision of inspecting in- strument is confirmed with practical experiments,and can be used for evaluating the dynamic characteristics of metro bogie exactly.更多还原
