摘　　要：为提高多能域耦合平面连杆机构动态静力分析的效率及可靠性,提出了回转键合图法。阐述了建立平面连杆机构键合图模型的一般方法及其动力学原理。基于回转键合图推导出便于计算机自动生成的完整形式的系统驱动力矩及运动副约束反力的统一公式,有效地克服了微分因果关系及非线性结型结构所带来的十分困难的代数问题,实现了计算机自动建模。实际算例表明了所述方法的有效性。In order to increase the efficiency and reliability of kinetostatic analysis for planar linkage containing the coupling of multi-energy domains, a method based on gyrobondgraph is introduced. The procedure of modeling planar linkage by bond graphs and its dynamic principle are described. The unified formulae of driving moments and constraint forces at joints are derived based on gyrobondgraph, they are easily generated on a computer in a complete form. As a result, the very difficult algebraic problem caused by differential causality and nonlinear junction structure ean be overcome, and the automatic modeling on a computer is realized. By a practical example, the validity of this procedure is illustrated.
