均质薄圆盘陀螺仪转子两种动力学特性的异同

The Difference and Parity of Two Kinds of Dynamical Property of Homogeneous Disc Gyroscope Rotor

运用陀螺仪近似理论和相对运动动力学理论对二自由度陀螺的进动运动和单自由度陀螺当转子轴被迫绕缺少自由度的轴转动时转子将产生绕具有自由度的轴转动这两种运动进行了分析，指出了两种陀螺动力学特性产生的原理与运动规律之间的差别.

Based on the gyro approximate theory and the relative motion dynamics theory, two topics are discussed first, they are: (1) precession of the Two-degree freedom gyro, (2) rotation of rotor around the single-degree freedom axis when a gyro axis is forced to rotate around an axis which lacks degree of freedom in a single-degree freedom gyro. And then the difference betWeen the principle which leads to these two kinds of gyro dynamics property and the law of motion is pointed out.
