| 摘 要： | 通过建立一个较完整的液压起升机构在起升作业时间的非线性多自由度动力学模型，采用自适应步长的四阶Ｒｕｎｇｅ－Ｋｕｔｔａ法，求解系统非线性动力学方程组，并对吊重瞬间离地起升这一典型工况进行动态仿真。另外，着重分析起升机构液压系统和机械系统的动态特性，为液压起升机构的设计提供了理论依据。

| Abstract: | This paper sets up a relatively complete nonlinear multi degree of freedom dynamic model of hydraulic hoisting mechanism for truck and crawler cranes,and solves the dynamic equations using adaptive four order Runge Kutta method.The typical operating condition of hoisting from ground suddenly is simulated dynamically with computer.The dynamic characteristics of hydraulic and mechanical parts of the hoisting mechanism are mainly analyzed.The result of this study provides a theoretical basis for the design of the hydraulic hoisting mechanisms for truck and crawler cranes. |
