The invention discloses a self-balancing centrifugal vibration excitation device which comprises a vibration exciter I, a vibration exciter II and a self-balancing device. The vibration exciter I andthe vibration exciter II are arranged in parallel; the mounting directions of the vibration exciter I and the vibration exciter II are consistent; the vibration exciter I and the vibration exciter IIsynchronously and reversely move; the vibration exciter I acts on a test piece I through a transmission assembly I; the vibration exciter II acts on a test piece II through a transmission assembly II;and the self-balancing device is connected with the transmission assembly I and the transmission assembly II, transmits force equal in magnitude and opposite in direction under the action of centrifugal force, and is used for balancing the centrifugal force borne by the vibration exciter I and the vibration exciter II. According to the self-balancing centrifugal vibration excitation device, centrifugal force borne by the two vibration exciters is automatically balanced through the self-balancing device, so that the vibration exciters do not deviate from the working zero positions of the vibration exciters and can normally work all the time.
本发明公开了一种自平衡离心激振装置,包括激振器Ⅰ、激振器Ⅱ、自平衡装置;激振器Ⅰ、激振器Ⅱ相互平行放置;激振器Ⅰ、激振器Ⅱ的安装朝向一致;激振器Ⅰ、激振器Ⅱ同步反向移动;激振器Ⅰ通过传动组件Ⅰ作用于试件Ⅰ,激振器Ⅱ通过传动组件Ⅱ作用于试件Ⅱ;自平衡装置分别与传动组件Ⅰ和传动组件Ⅱ连接,且在离心力的作用下进行大小相等,方向相反的力的传递,用于平衡激振器Ⅰ、激振器Ⅱ受到的离心力。本申请中两个激振器所受离心力通过自平衡装置自动平衡,使激振器不偏离其工作零位,始终能够正常工作。
