摘　　要：目前国内缺乏满足高超声速风洞气动热试验需求的快速运动装置。提出一种基于气液增速缸和伺服比例换向阀的快速运动装置设计方案。该方案解决了机构加减速的难题,使得机构快速运动装置插入时间达到试验要求。结果表明:该装置满足速度和冲击要求,能够应用于风洞测热试验。Fast-moving equipment which can meet the needs of aerodynamic heating tests in hypersonic wind tunnel is scarce at present in China, The design scheme of fast-moving equipment which was based on gas-liquid boosting cylinder and servo proportional valve was described. The design scheme solves the problem of changing meehanism＇s speed, so the time that the fast-moving equipment used to inserted into test section fulfills the test requirement. The results show that the equipment satisfies the speed and impact require- ments, it can be used in aerodynamic beating tunnel tests.
