英文摘要：

In order to improve the protective ability of emergency brake of high speed linear induction motor armature, the advantages and disadvantages of several passive energy absorbing structures are compared firstly, and the honeycomb is selected as energy absorption component of the emergency brake system with the consideration of the armature＇s structure and braking requirements. Then based on researching the specific structure, energy absorbing characteristics and key indicators of the honey- comb systematically, the selection of honeycomb and design method of emergency brake equipment are put forward. Finally, an example of the emergency brake systemrs design and its test validation are conducted. The research results show that the honeycomb is suitable for armature emergency brake system, and the design method is reasonable and feasible.
