| In order to solve the problems of long preparation time and low test efficiency caused by using brake pads in the traditional vertical tower seat ejection test, this paper proposes the use of permanent magnet eddy current braking for braking. Through theoretical calculations and numerical simulation, this paper studies the feasibility of fixed-point buffer braking of permanent magnet eddy current braking in the vertical drop test of the pulley, and optimizes the material scheme of the stator plate in the permanent magnet eddy current braking system on this basis. The simulation calculation results show that the permanent magnet eddy current braking system can meet the requirements of the vertical tower seat ejection test for a braking distance of 40 meters. The optimized stator plate material selection scheme is:high-speed braking section uses stainless steel, medium-speed braking section adopts copper-nickel alloy, and aluminum alloy is used in the low-speed braking section. |
