摘　　要：基于VS2005可视化虚拟软件开发环境,开发了一套共直流母线能量回馈电封闭式高转速试验台架,实现了测试微型变速器高转速下的多项性能。介绍了台架总体结构和测试原理,对台架重要组成部分进行了选型分析。实现了基于工业以太网的PLC S7-300与S120逆变控制器及CP1613网卡的通信,利用NI PXI-6221数据采集卡实现了模拟量输入和数字量输出,提出了高转速试验结果的评价标准。试验结果表明,该台架运行稳定可靠、精度高、操作方便,具有良好的扩展性。Based on VS2005 virtual software development environment, an electrically closed test bench with DC-bus to feed-back energy was developed which can test the comprehensive performance of mini-transmission under high-speed condi-tion. The selection of the important component of high-speed bench was analyzed. The overall structure and test theory were in-troduced. Based on industrial Ethernet, the communication between the PLC S7-300 and S120 inverter controller and CP1613 network card were realized. The high-speed acquisition of the testing process signals were realized through multifunction data acquisition card NI PXI-6221. The evaluation criteria of the high-speed test results were put forward. Test results show that the bench is stable, reliable and in high precision. It is easy to operate and has a good scalability.
