Abstract
In this paper, the concept and definition of Hula motion will be introduced. Furthermore, the Hula system and its applications will also be mentioned. In the analysis of Hula system, the motion of main mass is limited in one degree of freedom. There are two nonlinear differential equations developed for the Hula system with some assumptions. These two equations can be solved by approximate analysis and numerical simulation. The relations between system responses and system parameters can be revealed by the solutions of the equations of motion. The possibility of existence of the approximate analytical solutions can be evaluated by stability analysis. In addition, the motion of the Hula system about various system parameter settings can be analyzed by numerical method. In addition to approximate analysis and numerical simulation, the various behaviors of the Hula system are also observed by experiment.
