    摘要:

    为了实现导弹发射车状态监测传感器的优化布置,以原理分析为基础,重点运用AMESim仿真平台建立液压系统模型,模拟各测点传感器信号的特征和作用,通过分析传感器对故障的敏感性和信息量的大小,进行传感器类型和安装位置的优化,从而避免实验过程中研制周期长,经济上耗费大的问题,节约了实验成本。采用故障注入的形式得到模型各测点的仿真数据,研究分析各测点信号的特点及趋势,以及测点在故障情况下的特征响应,为传感器用于诊断进行探索。在此基础上,按照一定的原则进行传感器的选择与优化,进而确定监测传感器的布置方案,为导弹发射车液压起竖系统的状态监测、故障诊断与定位奠定基础。

    Abstract:

    In order to implement optimal placement of sensors of condition monitoring for hydraulic erecting system of missile launcher, based on analyzing of principle, AMESim simulation platform was applied mainly to built the model for hydraulic system, and the function and characteristics of signals of sensors at each monitoring point were simulated. Through analyzing sensitivity and size of information from sensors to faults, the types of sensors and placement of installation were optimized, thereby the problems such as long experimental time in development process, and high economic consume were avoided, and experimental costs were avoided. Simulation data were gotten in the form of fault injection at each point of the model, and characteristics and trend at each point of monitoring were analyzed and studied under the fault state, as well as for that of characteristic response, and the sensors used for diagnosis were explored. On the basis, sensors were selected and optimized according to certain principle, and then placement scheme of sensors was designated. It has laid the foundation for condition monitoring, fault diagnosis and placement to hydraulic erecting system of the missile launch vehicle.
