| 摘 要： | 为了了解轴系的弯曲振动和扭转振动之间可能会产生的相互激励问题，导出了集中质量的轴系弯扭耦合振动的微分方程。由微分方程可知，弯曲振动之间的耦合因素是十分复杂的。为了逐步弄清弯曲和扭转振动之间发生耦合的条件，选择“重力”这一最简单的耦合因素进行分析，并得出了一些初步的结论。

| Abstract: | In order to understand the coupling effects between latera and torsional vibrations in a rotor system, some differential equations are derived in the paper. It has been shown from the differential equations that the coupling conditions are complicated. Gravity, the simplest coupling factor, has been studied as the first step to gradually understand the coupling conditions between lateral and torsional vibrations. Some conclusions have been drawn and are expected to be halpful to further analysis. |
