Abstract
Under the actual working conditions, the shaft system of micro gas turbine is often subjected to torsional load due to a variety of factors. As the key flexible part connecting multi span rotor on gas turbine, the torsional characteristics of closed interference fit diaphragm coupling have the most direct impact on the static and dynamic torsional performance of the system. Based on this problem, by simplifying the solution model of the diaphragm coupling, this paper studies the torsional characteristics of the diaphragm coupling by means of simulation analysis, gives the deformation and stress distribution on the diaphragm and intermediate shaft under torsional load, and solves the torsional stiffness of the diaphragm coupling, It lays a foundation for further study on the influence of coupling on the dynamic performance of shafting and optimal design.
