Application of the Gauss minimum constraint theory in a rigid-flexible coupled system

Applying the Gauss minimum constraint theory, a finite segment modeling method is presented for a rigid-flexible coupled system. The cantilever beam's movement with considerable range is synthesized in the model, and the system's dynamic characteristic is expressed integrally. The simulation results and error analysis are given, which shows that the method has considerable precision. The Gauss minimum constraint theory has its uniform expression, and it can reflect the system's inertia effect. It is suitable for use in the modeling and analysis of a rigid-flexible coupled system.
