| Abstract: | This paper studied the performance movement characteristics of oil dashpot release using the software Emag and Fluent, considering the effect of the electromagnetic force, the oil resistance and spring force. The core motion equation was deduced. The feasibility of the simulation method was verified. The influences of the distance between core and oil cup, and oil viscosity on the performance characteristics were researched. At last, the experiment was carried out. |
