dcterms.abstract | The invention relates to a electromagnetic device used for negative stiffness. The magnetic device for negative stiffness includes one or more solenoids for generating a magnetic field. A moveable magnet is moveable relative to the one or more solenoids through the one or more solenoids. The one or more solenoids are configurable to generate an at least substantially quadratic magnetic field about an equilibrium position at which the resultant force on the moveable magnet is zero. Depending on the respective pole orientation, generating a quadratic magnetic field about an equilibrium position provides a substantially linear negative stiffness characteristic with displacement. The invention also relates to a vibration control method. | - |
dcterms.abstract | 本发明涉及一种用于负刚度的电磁设备,其包含用于产生磁场的一个或多个螺线管,以及可相对于该一个或多个螺线管而移动的可移动磁体。该一个或多个螺线管可被配置以在平衡位置周围产生对称的磁场,其磁场强度与距离平衡位置的距离成平方关系。可移动磁体在该平衡位置处受到的合力为零,根据相应的磁极方向和在设备中轴线方向产生的按二次方程分布的磁场强度,其所受合力与其位移成线性关系且合力方向与位移方向相同,即产生一种线性负刚度。本发明还涉及一种振动控制的方法。 | - |
