摘　　要：针对含有移动铰的机电耦合系统动力学建模与仿真问题,提出了相应的键合图法。基于平面移动铰的运动约束条件,阐述了建立平面移动铰键合图模型的一般方法及其动力学原理。在考虑混合因果关系情况下,推导出便于计算机自动生成的系统状态方程及运动副约束反力方程的统一公式,实现了含移动铰机电耦合系统一体化建模与仿真,通过实例说明本文方法的有效性。For the dynamic modeling and simulation of electromechanical coupling systems with translational joint,the corresponding bond graph procedure is proposed.Based on the kinematic constraint condition of planar translational joint,the procedure for modeling planar translational joint by bond graph is described,and its dynamic principle is presented.In the case of mixed causality,the unified formulae of system state space equations and constraint forces at joints are derived,which are easily derived on a computer.As a result,the unified modeling and simulation for electromechanical coupling systems with translational joint is realized,its validity is illustrated by a practical example.
