| Abstract: | The chemical compositions, casting properties and heat treatment techniques for the materials of brake calipers used on high speed EMU are presented. 3 types of brake calipers are produced, followed by static strength test, torque fatigue strength test and vibration fatigue strength test, and the testing re- sults indicate that the performances of the materials used to produce brake caliper can satisfy the requirements for brake operation of EMUs running at 200 - 300km/h. |
