Systematic Modeling Technique by using Function Power Graph on the Centrifugal Anti-Lock Braking System Simulation 2015-32-0745
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. In addition, comparison between the C-ABS and conventional ABS has been made. Finally, an experimental platform of the C-ABS has been set up and the experiment measurements are in agreement with our SimulationX-based simulation results. According to this systematic modeling technique of the FPG method, the characteristics of any new system structure can be easily identified. Then, through CAE software, such as SimulationX, a physical model can be easily created to achieve better performance and development of system design and system analysis.
