Abstract :
The requirements of higher train speed, safety and more smooth and comfortable travelling are increasing strongly. This leads the need of predictive maintenance. Tamping machines have been used for this purpose. Tamping machines on the market are mostly mechanically driven. A new hydraulically driven tamping device is proposed to overcome the limitations of mechanically driven machines. A new type of rotary valve is also designed to improve the control of oscillating tamping cylinder. Parametric analysis is carried out by establishing mathematic model. The results show that new tamper can meet the design requirement and the flexible adjustment of amplitude and frequency is realized.
