摘要：

Along with the development of structural construction, piles tend to be of bigger diameter and longer length, a single vibration hammer is difficult to meet the power requirement of striking lagre-diameter piles and synchronous vibration control of multiple vibrating hammers is an effective method to solve the problem. The basis principles of synchronous vibration control and corresponding methods were introduced. Synchronous control system based on field bus was designed, and an open distributed control network was built. Considering the working characteristics and mechanical properties of vibrating pile hammer, speed and phase synchronization controller was designed. The simulation research and experimental results show that the control method is effective with rapid response speed, strong robustness and good stability, and synchronous vibration of multiple vibrating pile hammers is achieved with the assistance of controller network, the velocity and phase differences between are able to satisfy engineering demands.
