Abstract:
In order to find out the principle of impact on the rocket launching system exerted by the dynamic load between the rocket and the launching tube during the unlock process of the lock mechanism,this paper analyzes the property and motion of the lock mechanism under the transient impact load by using the transient dynamics method.Forces,deformations and interactive dynamic responses of the directional stick,the retaining ring and the lock body are presented.The results indicate that the load between the lock mechanism and the rocket has significant transient properties,and the frequency between the directional stick and the retaining ring is 2 kHz.It is advised that the transient dynamics method should be used in the design and optimization of the lock mechanism.
