摘　　要：建立了桩锤上升、下降和保压等液压锤整个工作周期的数学模型,并进行了计算机仿真,为开发液压打桩锤产品提供了理论基础.The mathematic models of rising, falling and keeping constant pressure phases for hydraulic piling hammers are set up. The phases of the whole process are simulated by use of computer. All of the above mentioned supplies a method for developing hydraulic piling hammer products adapted to our country's conditions.
