摘　　要：基于Lab VIEW,NI Veristand和PXI平台对电控空气悬架进行了硬件在环仿真测试系统的设计研究。介绍了建立硬件在环仿真测试系统的方法,并在Simulink中建立了1/4空气悬架车辆模型和模糊控制器模型。使用Veristand将编译为DLL文件的Simulink模糊控制器导入到PXI-8102实时控制器中,结合上位机中的Lab VIEW程序控制1/4空气悬架模型,并采用道路试验采集到的位移信号模拟路面激励,进行联合仿真测试。搭建了1/4空气悬架试验台实物,替代Simulink模型作为被控对象,利用电液伺服激振台进行激励加载,完成硬件在环实时仿真测试。测试结果表明:所建立硬件在环仿真测试系统的有效性与可行性。The hardware-in-the-loop（HIL） simulation test system of electronically controlled air suspension system was researched based on Lab VIEW, NI Veristand and PXI platform. The establishment method of HIL simulation test system was introduced, and 1/4 model of air suspension vehicle and fuzzy controller model were built with Simulink. The fuzzy controller model is compiled to DLL file and imported to the real-time controller of PXI-8102 by Veristand, which used to control the 1/4 model of air suspension vehicle combined with the Lab VIEW program in PC, and the displacement signal obtained by road test is used to simulate the road excitation to conduct joint simulation test. A test rig of 1/4 air suspension vehicle was developed to replace the Simulink mode as controlled object, and electro-hydraulic servo vibration table was used to excitation to conduct HIL real-time simulation test. Test results show the validity and feasibility of the HIL simulation test system.
