通过对液压静力压桩机起吊系统的分析和研究,运用AMESim软件建立了液压驱动系统的仿真模型,并建立了钢丝绳的力学方程,分析了激励加速度对钢丝绳动张力的影响.对吊臂在不同动栽系数时,起吊系统的最大起重力及变幅油缸的最大油压与变幅角度的关系进行了仿真研究.通过仿真分析可知激励加速度的变化会引起动张力的变化,运用修正后的动载系数代替经验取值对模型进行力学分析,不但简化了运算过程也使结果更加准确.

Through the analysis and research of the lifting system of hydrostatic pile press, the simulation model of hydraulic drive system was established by using AMESim software, and the mechanical equation of the wire rope was established, and the influence of excitation acceleration on the dynamic tension of the wire rope was analyzed. The relationship between the maximum lifting capacity of the lifting system and the maximum oil pressure of the luffing cylinder and the luffing angle of the boom under different moving coefficients is carried out. Through simulation analysis, it can be seen that the change of excitation acceleration will cause the change of dynamic tension, and the modified dynamic load coefficient is used instead of empirical value to analyze the model mechanically, which not only simplifies the calculation process but also makes the results more accurate.
