基于PXI的六分力硬件测试系统设计与实现

Six Component Hardware Test System Design and Realization Based on PXI

为满足大吨位固体火箭发动机地面试验对测试的需求,对固体火箭发动机性能参数以及测试原理进行了深入的研究,组建基于PXI总线的发动机推力矢量、发动机燃烧室压力、发动机壳体变形量的综合测试系统;并搭建系统的硬件平台及软件平台;试验结果表明,该系统能够反映固体火箭发动机地面试验的健康状态,采集的特征参量满足技术指标,具有高可靠性和易操作性等特点,能成功用于固体火箭发动机地面试验中的各种测试需要。

In order to satisfy the measurement requirements which is used for large-tonnage solid rocket motor ground tests, after intensive study about solid rocket motor performance parameters and testing principle, a integrated test system on engine thrust vector and En- gine chamber pressure was established based on PXI bus. And then, software platform and hardware platform is formed, The test results show that the system can reflect the healthy state of the solid rocket motor ground test, collection of characteristic parameters could meet technical indicators, The system which features high reliability, easy operation and etc, can successfully be used to solid rocket motor ground tests in various testing needs.
