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. Simu-lation 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.
