摘要
本文简要介绍了新建成的 GXJ-100S 高压校准激波管系统,它由 GXJ-100高压校准激波管装置,气体供给与回收系统,电、气动控制与液压系统,测试与数据处理系统组成。其技术性能为:最大阶跃压力△P_s=109MPa,平台压力持续时间4～8ms,幅值不确定度小于±6%,不重复性小于±4%,平台稳定段压力不平度小于±2%,前沿上升时间小于0.05μS。文中还讨论了某些实际应用情况。
This paper is a brief describtion about GXJ-100S Highpressure Calibration Shock Tube which is just established.It consistsof GXJ-100 High Pressure Calibration Shock Tube,gas supplying andrecovering system,power and gas control system,hydraulic system,andmeassuring and data processing system etc.Its performances are asfollows:maximum step pressure △P_5=109MPa,duration time τ_5=4～8ms,amplitude uncertainty<±6%,reproducibility<±4%,front rise time<0.05μs,unevenness of plane portion≤±2%Some applied researches arediscussed in this paper.
