| 摘 要： | 阐述了建立含有移动铰的平面连杆机构键合图模型的一般方法.将运动副约束反力视做未知势源加在系统键合图模型相应的0-结处,不能完全消除系统键合图模型的微分因果关系.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驱动力矩及运动副约束反力方程的统一公式,克服了微分因果关系及非线性结型结构给计算机自动进行系统动态静力分析所带来的代数困难.所述方法特别适合于多能域并存的系统,通过实例说明本文方法的有效性.

| Abstract: | The procedure of modeling planar linkage containing translational joint by bond graphs is described.The constraint forces at joints can be considered as unknown effort sources and added to the corresponding 0-junctions of the system bond graph model,as a result,most of the differential causality in system bond graph model can be eliminated.Based on this,the unified formulae of system driving moment and constraint forces at joints are derived,they are easily derived on a computer.As a result,the algebraic difficulty brought up by nonlinear junction structure and differential causality can be solved,and automatic system dynamic and static force analysis can be realized on a computer.This procedure is very suitable for the systems containing multi-energy domains,its validity is illustrated by a practical example. |
