摘要
键合图是一种图形工具,它可以清晰形象地描述系统内部的能量结构。文中给出了功率键合图理论对汽车1/4、1/2悬架系统建模的详细方法,建立了1/4、1/2悬架的键合图模型。对1/2悬架键合图模型进行仿真时,文中没有采用传统的推导状态方程方法,而是将键合图模型按照键合图与方块图的转化关系直接转为方块图模型,再利用MATLAB软件的S imu-link工具箱对1/2悬架的方块图进行建模仿真。给出了仿真模型,得到了较好的仿真结果。验证了键合图结合方块图理论对系统建模和分析的优越性。
Bond graph is an explicit graphical tool for capturing the common energy structure of systems. Using Bond graph theory, this paper presents a method to modeling 1/4 and 1/2 car suspension system. The Bond Graph model of 1/4 and 1/2 car suspension systems is established. To simulate the Bond graph model of 1/2 suspension system, the paper does not deduct the state function but changes the Bond Graph model into Block Graph model directly according to the relationship of Bond Graph and Block Graph, Based on the Simulink Toolbox of Matlab, the simulation model is provided. The results of simulation indicate that Bond graph combined with Block graph is a better method for modeling and analyzing complex systems.
