机械系统动力学建模的联结方法──(Ⅱ)联结方法与拉格朗日法

The Connection Approach to Dynamics Modeling of Mechanical Systems (Ⅱ) The Connection Approach and the Lagrange Method

引入了位移联结、速度联结和加速度联结，从而使联结理论适用于非线性机械系统的动力学建模。为机械系统动力学建模提供了一种新的方法，也为联结理论在其它领域的完善和发展提供了参考和借鉴。将联结方法与拉格朗日法进行了对比，证明了联结方法的正确性，也显示了联结方法的优越性。

The displacement connection, the velocity connection and the acceleration connection are introduced to expand the theory of connection(TC) into dynamics modeling of nonlinear mechanical systems. This paper presents a new formulation for dynamics modeling of mechanical systems, and this achievement can be used as a reference to expand the TC into other fields. This paper also compares the connection approach with the Lagrange method to demonstrate the validity and advantage of the connection approach.
