Abstract
Pendulum Pattern, which was one of the non-graphics way, was well-developed in art, design and phototechnical area. The forms of Pendulum Pattern, which is defferent from the general expression in graphics. Today, the study of Pendulum Pattern itself is not developed as it is difficult to describe the basic rule. In this study, I describe Pendulum Pattern generated rules by mathematical principle modeling based on theories of non-linear dynamical systems. As a result I comfirmed the following. (1)The function of the bifurcation makes different generation systems transfer smoothly.(2)The bifurcation secures stability of movement.(3)There is a possibility that the function of the design is created by nonlinear dynamic systems.
