ObjectiveThe existing research on diaphragm couplings mainly focuses on the mechanical performance of different types of diaphragm couplings and the optimization of diaphragm size and shape through various optimization algorithms. There is relatively little research on the influence of diaphragm structural parameters on the mechanical performance of couplings under high torque and large deformation conditions. Therefore, a parameterized model of fan couplings was established through finite element analysis software Abaqus to explore the mechanical performance of nonlinear structures of fan diaphragm couplings under high torque and large deformation conditions.MethodsThe reliability of the simulation results was verified by analyzing the finite element stress results of the global model of the fan coupling. On this basis, different parameters of the waist structure of the membrane and the anisotropic stiffness and stress characteristics of the membrane under multiple membrane groups were studied, and the optimal combination of waist structure parameters and membrane layers under actual composite working conditions was obtained. And based on this combination model, multi-objective shape optimization of membrane structure was carried out.ResultsAs the number of layers in the membrane group and the parameters of the membrane waist structure increase, the isotropic stiffness of the membrane continues to increase. The number of layers in the membrane group is inversely proportional to the equivalent stress, and the parameters of the membrane waist structure are inversely proportional to the equivalent stress. By increasing the thickness of the stress concentration location on the membrane, it is possible to effectively reduce the maximum equivalent stress, disperse stress concentration phenomena, and improve structural stiffness. |
