新型打桩锤电液控制系统研究
Research on electro-hydraulic control system of new pile hammer
摘要
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 ana-lyzing 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 hit-ting 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.关键词
