依据流体力学的粘性阻力理论,以运动的转子构件--圆柱体为主体,利用矢量分析方法,导出了圆柱体在流体中横向振动时受到的流体阻力解析表达式.分析结果表明圆柱体在流体中横向振动时受到的阻力包括惯性项和阻尼项两部分,其动特性系数不仅与流体性质及圆柱体的结构尺寸有关,而且还与圆柱体的振动角速度有关.同时发现,惯性项中除了包括圆柱体在理想流体中横向振动时受到的惯性阻力外还增加了与粘性有关的部分;而阻尼项则由与粘性有关的两部分组成,其中一部分与流体密度有关,而另一部分与流体密度无关.导出的公式可用于转子系统的流固耦合动

According to the viscous resistance theory of fluid mechanics, the analytical expression of the fluid resistance of the cylinder when it vibrates laterally in the fluid is derived by vector analysis method, taking the moving rotor member - cylinder as the main body. The analysis results show that the resistance of the cylinder during the transverse vibration in the fluid includes two parts: inertia term and damping term, and its dynamic coefficient is not only related to the fluid properties and the structural size of the cylinder, but also related to the vibration angular velocity of the cylinder. At the same time, it is found that in addition to the inertial resistance of the cylinder when it vibrates laterally in an ideal fluid, the inertial term also adds a part related to viscosity; The damping term consists of two parts related to viscosity, one of which is related to fluid density and the other part is not related to fluid density. The derived formula can be used for fluid-structure interaction in rotor systems
