摘要
介绍非惯性系平面连杆机构动态静力分析的回转键合图法。给出非惯性系平面连杆机构键合图模型的建立方法。基于回转键合图理论 ,推导出便于计算机自动生成的完整形式的机构平衡力矩及运动副约束反力的统一计算公式 ,有效地克服了非线性几何约束及微分因果关系给建立机构平衡力矩及运动副约束反力统一公式所带来的十分困难的代数问题。所述方法特别适合于多能域并存的系统。结合实际算例说明本文方法的有效性。
A gyrobondgraph method for the dynamic and static force analysis of planar linkage in non-inertial coordinate system is introduced.The general procedure to model planar linkage in non-inertial coordinate system by bond graphs is provided.Based on the basic concept of gyrobondgraph, the unified formulae of balancing moments and constraint forces at joints are derived, they are easily generated on a computer in a complete form. The very difficult algebraic problem caused by differential causality and nonlinear geometric constraints in formulating the unified formulae of balancing moments and constraint forces can be overcome. This procedure is very suitable for systems containing multi-energy domains. By a practical example,the validity of this procedure is illustrated.
