A system to simulate the human circulatory system was built to investigate flow during arterial occlusive disease. The excitation of the system is provided by a microcomputer-controlled stepper motor which in turn drives a diaphragm pump. To derive the relationship between the pump displacement and the resulting simulated arterial pressure, the mechanical stimulation was simulated by an electrical system. The electrical system was represented by using a digital simulation language which allowed the component values of the electrical system to be varied until a desired match was obtained between input and output.
