摘要
以单摆作为研究对象,基于键合图建模理论,对单摆在理想状态下、考虑铰接点的摩擦和考虑摆杆质量3种情况进行了动力学建模分析,分别建立了3种工况下的键合图模型,并给出了相应的状态方程,通过得到的摆动运动模块化键合图模型,能方便的将摆动运动作为一个整体,与其它键合图连接。最后以复杂曲面零件转动惯量的测试为例,比较了键合图建模方法与牛顿力学建模方法建立的动力学模型。
Based on bond graph modeling theory,we carry out kinetic modeling analysis of a pendulum in an ideal state considering the friction between hinged point and swing rod and the quality of the swing rod.We present the bond graph modeling method and the corresponding equation of state for the swing problem,and set up three kinds of bond graph models in three different cases.Then,we derived the corresponding state equations.Taking the test of moment of inertia of complex curved surface as example,we compared the bond graph modeling method with the modeling method by Newton′s mechanics.The results indicate that the bond graph modeling method is correct and feasible.
