In power transmission area, researchers have carried out multi-body systems analysis regarding timing belt train and timing chain train systems. And past several years there has been increasing interest in analysis of power transmission system related with nonlinear contact, small mass link segments and high speed problem. In these kinds of analysis, solving time is taken a lot to get numerical results according to complicate characteristics of the systems. Because the behavior of link segments is the one of most significant facts from getting accurate numerical results point of view in detail design. However, in earlier step of systemic design, one of the most important points is to extract a trend of systemic behavior in short time. In this study, multiple axes chain coupler is presented in order to apply to systemic design. The object of this approach is to help to get systemic trend in the early design step. In this approach, first, screw force is used to represent tension and torque acting on the system. Second, distance change between timing chain sprockets is applied to represent vibration of sprockets. Third, stiffness coefficient and damping coefficient are used to generate tension and torque. A timing chain system, which consists of chain sprockets, chain link segments and guide rails, is used for validation comparing with proposed method. As a result of these approaches, multiple axes chain coupler enables to get reasonable systemic trend comparing with multi-body system of timing chain in short time.
