摘要：

为提高打桩锤的打桩质量和工作效率，提出一种基于插装阀设计的新型大流量液压打桩锤。通过分析该打桩锤电液控制系统的结构组成和工作原理，建立了液压系统驱动桩锤打桩的动力学模型。基于AMESim平台构建了打桩锤电液仿真系统，同时搭建了实验平台，对桩锤锤击过程动态特性进行仿真和实验研究。仿真和实验结果表明该系统在满足液压打桩锤基本性能的前提下，还具有实现打击能的无级调节、打桩锤控制效率高、换向压力波动小，以及能保证打桩能量和打击重复精度等优点，为优化桩锤参数和开发新型液压打桩锤产品提供了重要依据。

Abstract:

In order to improve the pile driving quality and work efficiency of pile hammer, a new large flux hydraulic pile hammer which is designed based on cartridge valve is presented. By analyzing the structure and working theory of the electro-hydraulic control system of the pile hammer, the dynamic model of hydraulic system driving piles to hit piles was established. And the electro-hydraulic simulation system of pile hammer was constructed based on the AMESim platform, and the experimental platform was established. The dynamic characteristics of the hammer hitting process of the pile were simulated and studied. The simulation and experimental results showed that not only the basic functions of the hydraulic pile hammer could be satisfied, but also the hitting energy could be regulated steplessing by the system. In addition, the control efficiency of the hammer was high and the reversing pressure fluctuation was small, and the hitting energy and the repeatability accuracy could be guaranteed. It provides an important basis for the optimization of pile hammer parameters and development of new hydraulic hammers.
Key words: pile hammer    stepless adjustment    AMESim model    dynamic research
