制导炮弹高发射过载和高滚转角速度的特点使得惯性导航系统在其上面的应用难以得到有效实现，针对上述问题提出了一种半捷联式惯性导航平台系统，该系统利用所设计的半捷联式平台实现转移发射过载和隔离滚转运动的功能，从而为惯性导航系统在制导炮弹上的应用提供了条件。利用牛顿法对所设计的半捷联式平台进行动力学分析，并建立动力学方程。利用龙格-库塔法对所建立的方程进行仿真求解，得到半捷联式平台内筒的角度和角速度曲线。在飞行仿真转台上进行实验，验证了仿真结果，为进一步研究半捷联式惯性导航系统的工作性能提供了依据。

The high launch overload and high roll rate characteristics of guided projectile make it difficult for application of inertial navigation system. To address this problem, a solution of partial strapdown inertial navigation system is proposed. The system uses the partial strapdown platform to transfer the launch overloading and isolate the rolling movement, in order to provide the conditions for the inertial navigation system application in guided projectile. Dynamic analysis is accomplished for partial strapdown platform using the Newton method. The dynamical equation is established, and is solved using the Runge-Kutta method. The curve of angle and angular velocity for the platform are obtained. Turntable experiments were conducted to verify the simulation results.
