【Abstract】 The dynamics model of the system has been established based on the characteristics of the elastic foundation of forging hammer.The solution of the model has been given using RKF(Runge-Kutta-Felhberg) algo-rithm which has high precision and high numerical stability.The vibration states of the foundation of the hammering block and concrete have been simulated in different excitation conditions, different spring stiffness and damping conditions.Furthermore, the impacts of following parameters such as spring stiffness, the damping coefficient of damper and the concrete quality on isolation effect have been discussed, which provide theoretical foundation for the design ofelastic foundation offorginghammer.更多还原
