| 摘 要： | 卷扬提升子系统是一个二阶系统，很容易进行动态特性分析，液压均衡子系统是一个一阶系统，无法求其动态响应．针对两个子系统的动态数学模型存在的特点，提出了一种动态耦合的综合理论分析方法，其核心是将液压平衡子系统的动态方程耦合到卷扬提升子系统的动态方程中，因为卷扬提升子系统是一个二阶系统，故综合动态方程最终是一个二阶方程．建立了耦合的数学模型，并用数值直接积分方法计算了提升过程中系统的动态响应．

| Abstract: | It is easy to analyze its dynamical characteristic for lift subsystem because it is a structural system. Inertia caused by mass in hydraulic subsystem is ignored so that it is difficult to get its dynamical response. Considering the characteristics of the two systems, a dynamic coupling synthetically method was put forward. The key is that the dynamic equation of hydraulic subsystem is coupled into the equation of lift subsystem. For the inertia caused by mass in lift is considered, the dynamical synthetical equation is a structural equation. The coupling mathematical model was established. The dynamic response during lifting was calculated by using numerical integral algorithm. |
