陀螺动力学系统计算机仿真

THE COMPUTER SIMULATION OF GYRO DYNAMICS SYSTEM

推导出了适于计算机仿真的陀螺完整运动方程式并给出了仿真曲线,可看出在外力矩作用下陀螺仪从起动到稳定这一段时间内的转动角速度和转角的变化规律。通过降低陀螺转速并减小外力矩,使无锁紧机构的陀螺仪消除起动时的剧烈抖动而达到平稳起动的目的。

This paper derives the complete gyro motion equations which are suitable for compu ter simulation and plots the simulation curves. From these curves we can see the variation laws of rotational angular velocities and rotational angles of gyro from start to stability under the external torque actions. And it can be seen that through decreasing the gyro spin rate and the external torques the violent vibration of the gyro without locking mechanism can be eliminated so that the purpose of smooth start can be achieved.
