So the design method given in this paper avoids the blindness of the design of the antenna, decreases the waste of the antenna fabricates repeatedly. On the other hand, this method takes advantages of the geometrical theory and the nonlinear optimization, so it can be used in a wide region. This leads us a new road to design conformal array in the complex electromagnetic environment.

The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.
