中文摘要:
      基于液压桩机原理,通过增加受击夹桩箱及拉杆等结构,设计了新型顶拉式液压动力沉桩机,使受击点在预设范围内;经外加固定隔音层,可降低噪声以适应环境要求.借助AMEsim建立顶拉式沉桩机液压、负载系统模型及相应元件子模块,进行动态仿真研究.结果表明:系统最大打击能量、频率和冲击锤下冲加速度等参数均符合设计要求.针对改变拉杆弹簧刚度参数,分析其对冲击系统的影响,对液压动力沉桩机的研究和开发具有指导意义.
英文摘要:
      Based on the principle of the hydraulic pile driver, in order to make the strike point in the preset range, the striken clamping boxes and trolley structure were added and a new type of top-pull hydraulic power pile drive was designed. To meet the environmental requirements, the noise was reduced by adding fixed soundproof layer. The model of hydraulic-load system and the corresponding component sub-modules were established and simulated by applying the software AMEsim. The result shows that the main parameters of the system were comply with the design requirements, such as the biggest striking energy, frequency and impact hammer undershoot acceleration. By changing the rod spring stiffness parameters, the influence of the impact system is analyzed, which provide a guiding significance for the researching and developing of hydraulic dynamic pile-driver.
