A systematic modeling methodology using Function Power Graph (FPG) to analyze mechanical systems is proposed in this paper, and the novel Centrifugal Anti-lock Braking System (C-ABS) is used as the example. In this paper, a systematic modeling process combined with the FPG method and SimulationX-based modeling has been demonstrated. First, schematic diagram and working principle of the C-ABS model has been developed and illustrated. Based on the FPG method, several symbols (power unit, clutch/brake unit, and connection unit) for the C-ABS have been introduced. Second, system mode, operation, and function inspection of the C-ABS have been analyzed. Then, each component model of the C-ABS (wheel, disc brake, gearbox, and centrifugal braking device) has been established, and then the schematic diagram of the C-ABS has been transferred into practical image of the system structure (or physical model) through SimulationX to identify the dynamic characteristics of the C-ABS.
