Abstract：
|
|
The model Anal(?)sis of 2.5 t.m Pneumato-Hydraulic Power Hammer (PHPH in short) are given in this Paper. Two-degree-of-freedom model is identified. The distances, Veiocities and accelerations of PHPH are Rotten with this model, also the dynamic forces of fundation and ruber paddings. The reasonable stiffness of ruber padding is presented. It is than used to design a cost-effective Vibration isolator. The measured results show that the acceleration of foundation is cut up to 44% by using this Isolator.
