Linear and Asymmetric Rotors – Every Science

WebAnother simple rotor model, commonly used to study the fundamental rotordynamics, is a symmetric rigid rotor on two identical flexible supports, as illustrated in Figure 3.1-3. The rotor is considered rigid and symmetric. Again, the translational and rotational motions at the center of mass are decoupled and can be studied separately, as shown in In rotordynamics, the rigid rotor is a mechanical model of rotating systems. An arbitrary rigid rotor is a 3-dimensional rigid object, such as a top. To orient such an object in space requires three angles, known as Euler angles. A special rigid rotor is the linear rotor requiring only two angles to describe, for example … See more The linear rigid rotor model consists of two point masses located at fixed distances from their center of mass.
