【Abstract】 The electromechanical devices of long-distance rocket launcher, such as mechanism, hydraulic and air pressure system, electric power drive equipments etc, have various complex configurations, demand periodically frequent maintenance. Firstly, on the demand of a certain native newest rocket launcher project, the content of fault detection and device maintenance is totally analyzed. Secondly, all the methodology of precision measure and fault detection of different devices and system functionality is discussed in detail and put forward. Then, several kinds of appropriative detection equipments are developed. Finally, the system design of maintenance vehicle is reviewed.Aiming at measuring collimation precision of launcher, the measure process and algorithm based on theodolite is investigated systemically, then the collimation precision measure system by two theodolites is researched and developed, which fulfills all measure items of collimation precision on the self platform. The precision of Two-Theodolite system is ten times higher than the traditional scheme, and its efficiency is also increased dramatically. As far as servo system inspection, that fault is positioned and isolated by online monitoring dynamic pressure is employed. As for missile closedown mechanism, one new closedown force measuring device is devised, whose reliability and precision are both improved. Furthermore, the device can keep the closedown mechanism from damage due to measure. With respect to camion control system, ATE is adopted to realize the functionality of integrated detection for control case, manipulator, booster etc. Principle repository and experience repository are both integrated into the diagnostic expert system, which syncretize all kinds of detection means to heighten the diagnosis efficiency.Some key technology of rocket launcher maintenance is resolved in this subject, and the detection devices above have already been equipped into the maintenance vehicle of certain native long-distance rocket launcher.更多还原
