液压起升机构起升过渡过程的仿真研究

A simulation for hoisting transition process of hydraulic hoisting equipment

液压起升机构起升过渡过程的仿真研究建立并分析了液压起升机构在起升平面内的三质量三自由度的非线性振动模型。用数值方法求解了系统拉动方程级。对不同输入下的系统动态过程进行了仿真研究。

In this paper,a three masses and threedegress oscillation model about hydraulic hoisting equipment:are set llp and analyzed. The nonlinear differential equationsare solved with numeral method. The dynamic process of thesystem is simulated with different inputs. The calculatingmethod of dynamic load coefficent is derived.
