转子定轴转动时轴上附加压力计算的研究

Study on the Calculation of Additional Pressure on the Axis of A Rotor during the Rotation by the Fixed Axis

利用动量定理和角动量定理推导出了刚体定轴转动时的轴上附加压力的一般表达式,并对正方板和正三角板的轴上附加压力作了计算,给出了参数表达式,针对具体实际情况进行了分析讨论,得出转子在高速转动时作用在轴上的附加压力相对于重力产生的压力要大很多,并且同质量的三角形转子比正方形转子产生的附加压力要大。所得的结果为转子的设计、安装提供一定的理论参考。

In order to study the size of additional pressure on the high-speed spinning axis,the momentum theorem and angular momentum theorem of rigid body are used to calculate the additional pressure on the shaft of high-speed triangular rotor and square rotor.The parameter expressions are proposed and the actual situation is discussed.The results can provide a theoretical reference for the design and install of rotors.
