The design principle of vibration hammer pile driving principle is

Design and calculation of vibration, the main parameters of Exciter: frequency, frequency, and eccentric moment, vibrating, vibrator quality, amplitude and power.
Design process can be carried out according to the following steps:
1.according to the intended use and formations determine vibrator types, frequency, torque. the oscillator frequency and angular frequency and amplitude.
3.preliminary estimate vibrator and hole quality.
4.calculation of eccentricity.
5.calculate the engine power.
6.check vibration.
7.calculate the maximum pulling force.
8.structural design for vibrator of vibration hammer and modify parameters estimation based on actual design situation.
