摘　　要：液压打桩锤是一种新型的打桩设备,其动态性能的好坏直接影响打桩质量及打桩效率;在分析新型氮爆式液压打桩锤工作原理的基础上,建立桩锤上升和下降阶段的数学模型;并对同一控制压力、不同氮气初始压力下的几种工况进行仿真,通过对比、分析,确定该控制压力下的最佳氮气初始压力;为开发液压打桩锤产品和优化桩锤参数提供理论依据。Hydraulic pile hammer is a new type of piling equipment,its dynamic capability has directly effect of the piling quality and efficiency. On basis of analyse the work principle of the new hydro-pneumatic piling hammer, the mathematic models of rising and falling for hydro-pneumatic piling hammer are set up;and the work conditions of different initial nitrogen pressure under the same control pressure are simulated by use of computer, the best initial nitrogen pressure under the control press is determined by contrast and analysis;all of the above mentioned supplies a method for developing hydraulic piling hammer products and optimizing parameters of pile hammer.
