摘　　要：本文以行人保护测试系统发射装置为研究对象,采用高速液压弹射控制技术,分别阐述了发射装置的构成、高速液压缸的结构设计、高速液压发射的控制原理及电气控制系统。最后通过对各种冲击模型的实际测试进行了验证,结果表明:其发射速度稳定、准确、可靠,达到了试验要求。该装置可缓解目前国内行人保护测试设备主要依赖进口的局面,形成了采用高速液压缸进行行人保护试验测试设备的专有技术。In this paper,taking the pedestrian protection test system launcher as the research object and based on the high speed hydraulic ejection control technology,the structure of the launch device,as well as structure design of the high speed hydraulic cylinder and the control principle of high speed hydraulic launching and electrical control system is introduced respectively.Finally,verification tests are carried out for various impact models.The test results show that the launch velocity is stable,accurate and reliable,which meets the test requirements.The proposed device can alleviate the situation that the domestic pedestrian protection test equipment is mainly dependent on import,which forms a proprietary technology of using high-speed hydraulic cylinder for pedestrian protection test equipment.
