摘要
研究液压管路的动态特性及其仿真实现方法对液压系统优化设计及其性能分析具有重要的意义。根据包含有动态摩擦项液压管路分段集中参数建模的思想,以功率键合图推导出的输入势输出势模型为基础,提出应用Matlab软件中的动态仿真工具Simulink软件包对液压管路的动态特性进行仿真的分析方法,液压冲击实例表明该仿真方法应用于管路的动态分析实用方便;创建的管路模型及得出的仿真结果可为液压集成块和其他液压管网动态特性的研究提供借鉴。
It is essential to study pipelines' dynamic characteristic and their simulation method for the optimizing design and performance analysis. A simulated method was introduced to the pipelines' dynamic characteristic based on the idea of hydraulic pipelines' model of sectional lumped parameter with the dynamic friction and input & output model of bond graph, The hydrodynamic shock test proves that the simulation method is suitable for pipelines' dynamic analysis. The model of pipelines and the simulation results can give useful information to improve the design of hydraulic manifold block and other pipeline nets.
