Abstract：In order to explore the application characteristics of the planar eddy current damper in impact environment, a numerical simulation study on the response characteristics of the planar eddy current damper under high impact load was carried out. Based on the ANSYS Maxwell electromagnetic finite element software, a two-dimensional numerical simulation model of the planar eddy current damper was established, and the effects of the structure size of the permanent magnet and the magnetic shoe, the thickness of the conductive layer and the magnetic conductive layer, and the air gap distance on the electromagnetic damping force were analyzed. The research results show that the planar eddy current damper can meet the high impact load generated when a certain type of artillery is safely braked, and the damping phenomenon will occur at high speed. When the thickness of the permanent magnet increases from 10 mm to 50 mm, the magnetoresistance force increases significantly, and the mass utilization ratio reaches the maximum when the thickness of the permanent magnet is 30 mm. The magnetoresistance force tends to be saturated when the thickness of the magnetic guide plate exceeds 2 mm. When the thickness of the conductive plate increases from 0 to 0.6 mm, the magnetoresistance force increases proportionally, but when the thickness of the conductor plate increases from 0.8 mm to 2 m The results can provide support for the further application of planar eddy current damping in shock environment.
