| Abstract: | Because of resonance,when the train moves at the speed of V0,it acn make the strong shock,send out clickety clack noise.According to mechanics principle,adding the tubber packing between the wheel and the carriage compartment can change the elasticity coefficient of strut system,inthis way,it may eliminate the train clickety clack noise. |
