摘　　要：在分析键合图理论基本原理和特点的基础上,重点探讨了键合图理论在汽车线控转向系统中建模技术的应用,根据线控转向系统的工作机理和结构特点分别推导出转向盘系统和前轮转向系统的状态方程。采用Matlab/Simulink对建立的数学模型进行仿真分析,结果表明:应用键合图理论建立的模型能较好地反映线控转向系统的动态转向特性。Based on the fundamental principle and characteristics of bond graph theory, application of bond graph theory in modeling the steer by wire system was discussed, and the state equations of steering by wire system including the steering wheel system and the front wheel system were established by studying mechanism of steer by wire system. The simulation results showed that by building simulation model with Matlab /Simulink, the dynamic characteristic of steer by wire system could be expressed. The design basis and theoretical analysis method of further research on the steer by wire system were also provided.
