摘要: 在机械振动系统中采用螺旋飞轮运动转换系统,可以降低系统总质量,并获得良好的振动特性。为了推广螺旋飞轮的应用,降低集成设计的复杂性,通过对螺旋飞轮进行动力学分析,将其动力学特性进行封装。在传统力—电流机电比拟理论的基础上,提出一种新的无并联接地约束的电容元件来比拟螺旋飞轮,一方面解决了螺旋飞轮的比拟对象问题,另一方面完善了传统的机电比拟理论。应用电路网络的方法来研究机械振动网络的设计问题,给出基于螺旋飞轮机电比拟的机械振动系统的设计步骤。按照所提出的设计理论,在一个单自由度隔振系统实例中设计应用螺旋飞轮,实现传统振动元件无法实现的新型机械网络和隔振效果。结果表明所提出理论方法的有效性,为在机械振动系统中集成设计螺旋飞轮运动转换系统奠定了理论基础。

Abstract: A mechanical vibration system with spiral flywheel motion transformation system has merits of lower total mass and better vibration performance. In order to promote its application and reduce integrated design complexity, the dynamical activity of the spiral flywheel is encapsulated with the dynamical analysis. According to traditional force-current electromechanical analogy theory, a novel capacitor component without parallel or grounding constraint is proposed to analogize the spiral flywheel. The component can not only solve the analogy problem for the spiral flywheel, but also perfect the traditional electromechanical analogy theory. The circuit network method is employed so that design steps for the mechanical vibration system based on the spiral flywheel analogy can be presented. In the light of the proposed design theory, the spiral flywheel is applied in a single DOF vibration isolation example for desired performance. Thereby a novel mechanical network and vibration isolation effect that cannot be realized by traditional vibration components are realized. The result shows the effectiveness of the method, which lays a theoretical foundation for integrated design of the spiral flywheel motion transformation system in the mechanical vibration system.
