coupled motion meaning in English
耦合运动
Examples
- Within this analytical model , the factors as unsteady aerodynamic and blade flap / lead - lag coupled motion are both considered
旋翼机体耦合动力学模型考虑了非定常空气动力和桨叶挥舞摆振运动耦合。 - The rolling and the horizontal motion of ship are coupled intensely . meanwhile , the coupling motion is often presented as non - linear function according to experiment results and the ship is usually disturbed by sea wave when it cruises
船舶的横摇运动与水平面运动是强烈耦合的，而这种相互耦合的运动根据试验数据往往被拟合为非线性函数的形式，同时船舶在海上运动又会受到海浪的干扰作用。 - The natural frequencies of the antenna are low and dense because of its large dimension , light mass and large flexibility . dynamic analysis is needed to avoid the coupling motion between the satellite and the antenna . firstly the thesis sets up the dynamics model of the satellite - antenna system based on the hybrid coordinates
由于天线尺寸大、质量轻、柔性大，天线的固有频率很低且十分密集，为避免天线与卫星的调姿运动产生不良耦合影响，需对大型可展开天线与卫星系统进行刚柔耦合动力学分析，从而为天线的结构设计提供可靠的理论依据。 - Base on review of existed study and application in suppressing cable vibration in the world , technique of mitigating cable vibration with viscous damper and mr damper has been investigated in this dissertation , and the main contents and progresses in form of summary are as following : 1 the motion differential equations of the cable - damper system are formatted , which take into account these factors , such as the inclined angle , sag , stiffness etc . coupling motion between cable and deck is studied with analytical and numerical method . numerical results show that large amplitude vibration of cable with beat rhythm will occur when exciting frequency of deck equals two times modal frequency of cable
本文在对国内外斜拉索振动控制研究与应用现状进行综合评述、分析的基础上，针对上述问题进行了深入研究，具体的研究内容和取得的成果包括： 1 、建立了斜拉索-阻尼器系统运动方程，对拉索与桥面的耦合振动作了分析和研究，数值结果显示当桥面激振频率等于某阶拉索模态频率的两倍时，很小的初始扰动将引起拉索的大幅振动，并呈现拍振的特征，与实测的拍振信号一致。 - This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency . the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result . it is shown that a thrust force exists when the wing is in heave motion
深入系统地分析了存在表面效应时机翼运动规律和气动力之间的关系，研究结果表明，机翼升沉运动产生的推力与升沉速度幅值的平方成比例，推力和推进效率和振荡频率成反比；机翼的俯仰运动可以调节推力和推进效率，但是单纯的俯仰运动不会产生推力。
