英文摘要：

Under the application background of impact testing plant for high speed train, scheme de- sign and mechanical analysis of armature of linear induction motors （LIM） with high-speed and heavy- load are carried out firstly. Then, the stress of critical components is analyzed by finite element me- thod. Finally, five principles for the structure design of the armature are proposed. The results of pre- sent research show that it is feasible to use the armature of this kind structure concept design in the application of the impact testing plant.
