In order to accurately acquire the motion characteristics of the launch process of a vehicle borne missile electromagnetic ejection device, a multibody dynamics model is established by using ADAMS, and launch stability of the ejection device under the effect of recoil force and braking counterforce is analyzed. The results show that: in the process of missile firing, the rear part of the electromagnetic ejection device has a certain upward and backward movements, but there are within the acceptable range. The electromagnetic ejection device has good launch stability and its technology application to a missile firing is feasible.
