Abstract

We study the damping efficiency of torsional vibrations of a body using a dynamic vibration damper containing a system of successive impactor pairs with magnets as colliding elements. Dimensionless essentially nonlinear differential equations of motion of the protected body and magnetic elements are obtained. The influence of the designed parameter selection of the vibration damper on the vibrations of the carrying body is considered. The features of damper tuning in a wide vibration damping band mode are described. The optimal variant of damper tuning with the most effective damping of body vibrations is established.

带有磁冲击对的扭转振动阻尼器的动力学特性

摘要

我们使用动态减振器研究人体扭转振动的阻尼效率,该动态减振器包含一个以磁铁为碰撞元素的连续冲击器对系统。获得了被保护物体和磁性元件的无量纲的基本上非线性的运动微分方程。考虑减振器的设计参数选择对承载体振动的影响。描述了在宽振动阻尼带模式下阻尼器调谐的特征。建立了阻尼调整的最佳变体,可以最有效地阻尼车身振动。
