Abstract

The invention provides an eddy current damping characteristic testing device, comprising: a bottom plate, support plate, a screw nut mechanism, a guide rail, an L-shaped plate, a vertical beam, a support member and a cantilever beam wherein the guide rail, the vertical beam and the screw nut mechanism are mounted on the bottom plate. The eddy current damping characteristic testing device further comprises: an exciter, a force hammer, an accelerometer, a data acquisition card, a computer, a neodymium magnet disposed on the L-shaped plate, a scale A provided on the guide rail, and a scale B provided on the vertical beam. The vertical beam is fixedly connected to one end of the bottom plate through a bolt; the screw nut mechanism is installed at the other end of the bottom plate; the guide rail is mounted at two sides of the screw of the screw nut mechanism and is parallel with the screw. Through the adjustment of the screw nut mechanism, it is possible to enable the support plate and the L-shaped plate in connection with the support plate to slide on the guide rail. One end of the support structure is connected with the cantilever beam while the other end of the support structure can cooperate with the vertical beam in a vertically sliding manner so that the cantilever beam can be driven to slide vertically.

Description

technical field [0001] The invention belongs to the field of mechanical vibration, and in particular relates to an eddy current damping characteristic testing device, which aims at testing the eddy current damping device which can be used to suppress mechanical vibration. The eddy current damping characteristic testing device produces eddy current damping effect on the external magnetic field of the vibrating cantilever beam. The vibration frequency and speed, the distance between the cantilever beam and the magnet are analyzed for the change characteristics of the eddy current damping characteristics. Background technique [0002] Mechanical vibration is ubiquitous in various mechanical equipment. If the amount of vibration exceeds the allowable range, the mechanical equipment will generate large dynamic loads and noises, which will affect its working performance and service life, and in severe cases will lead to early failure of components. Due to the increasing complexi...
