Abstract

Give the fact that the double-deck rail demonstrates excellent performance in preventing rails melting and gouging during EML tests, theory and simulation research was carried out on the lateral vibration of the double-deck rail and contact properties between the armature and the rail in this paper. We deduced the lateral vibration contact equations of the double-deck rail by simplifying electromagnetic rail launcher as Bernoulli-Euler model based on the elastic foundation. A finite element code was used to help us model the launch progress. Influence of the double-deck rail scheme and rail height ratio was also analyzed. Both the characteristics of the contact surface between the rail and the armature and the displacement of the armature were considered. The results show that the double-deck rail can inhibit the propagation of bending waves and efficiently reduce rail gouging, beside, the double-deck rail height ratio has much influence on this effect.
