Dynamic Analysis Of Inertial Platform For Cruise Missile

The inertial navigation platform is one of key parts of inertial navigation system. Its working accuracy and reliability would affect the accuracy of inertial navigation system and space aircraft. The dynamic and static characteristics of the platform structural system have direct impact on the working precision and reliability of the entire platform system. This paper mainly introduce the new Russian cruise missile inertial navigation platform, which not only have all the advantages of domestic inertial navigation platforms, but also have the advantages of small size, light weight, stable performance characteristics, composed by mechanical structure of platform, steady loop, acceleration rebalance loop, output device, temperature control system, the initial alignment system, auxiliary power and secondary power of using in testing and other components.This paper analyses the inherent dynamic characteristics of the inertial navigation structure system and various structural components, and the frequency response of them in the vibration environment from the view of inertial navigation platform structure system, by using the method of combining static and dynamic experiments and analysis, firstly, modeling it by using UG software, and then do finite element structural analysis and dynamic modal analysis for it. This paper focuses on the problem of the inertial platform system that happened in the experiment, and has analysed the dynamic characteristics of the inertial navigation structure system by using the method of finite element analysis. The first chapter introduces the object of study ,the domestic and international background and significance of thesis research; Chapter II analyses the inertial navigation platform kinematics, does the associated modeling, analysis, and give tuning technology such as swing technology and so on; Chapter III describes inertial navigation platform dynamic analysis and vibration control technology; Chapter IV does the dynamic analysis of cruise missile inertial navigation platform; Finally gives the conclusion.This research should be a solution to the real problem in the inertial platform system, It's shown that not only the working environments but also the design and optimization of the same type of the platform would be improved .
