PROJECT TITLE :
Study of Properties of the Double-Deck Rail in the Electromagnetic Launching System
Based on the actual fact that the double-deck rail demonstrates glorious performance in preventing rails melting and gouging during electromagnetic launch tests, theory and simulation research studies were meted out on the lateral vibration of the double-deck rail and contact properties between the armature and the rail during this paper. We have a tendency to deduced the lateral vibration contact equations of the double-deck rail by simplifying the electromagnetic rail launcher as Bernoulli-Euler model based mostly on the elastic foundation. A finite-component code was used to help us model the launch progress. The influence of the double-deck rail theme has been analyzed. Each the characteristics of the contact surface between the rail and the armature and therefore the displacement of the rail were thought of. The results show that the double-deck rail can inhibit the propagation of bending waves and efficiently scale back rail gouging. Besides, the connection method of the two decks has a lot of influence on this impact.
