In this paper, the motion model of rubber diaphragm in diaphragm pump fluid end has been established by fluid-structure interaction model of finite element analysis software ADINA. Motion process of rubber diaphragm propelled by hydraulic oil in piston cylinder was simulated by fluid-structure interaction analysis. According to the simulation result, the volume of hydraulic oil for finishing stroke of rubber diaphragm can be confirmed. The simulation results were compared with the rubber diaphragm stroke experiment. The correctness of simulation results can be verified and the results provide some theoretical guidance for drawing up design plan of fluid end of diaphragm pump.
