Structure characteristic of motor bushing with radial/axial stiffness ratio >50 used in high-speed EMUs was introduced.Through FEA, type test and actual running service, the bushing with the structure of the high radial/axial stiffness ratio was proved could support the motor mass, endure the reaction force of the motor and resist the high temperature from the motor, which provided a solution to realize the rubber bushing with more than 5 rubber layers.
