Abstract

MULTIPLE DIAPHRAGM COUPLINGs are a special type of flexible couplings of rotary equipments. These couplings are designed in multiple thin diaphragms instead of thick one to reduce the loads transmitted to the equipments and stresses induced to the diaphragms in MISALIGNMENT. Because of need for different analyzes, such as static and dynamic analysis, modal, thermal, creep, fatigue and combination of these, and low stresses and flexibility, the design process of diaphragm coupling are complex, time consuming and usually performed iteratively. In many of these analyzes, the finite element solution is practically the only solution method. However, if we give ANALYTICAL SOLUTIONs for some of the analysis, the design process will be simpler and finding the optimum design is much faster. In this paper the exact ANALYTICAL SOLUTIONs for calculation of deformations and stresses in the diaphragms under axial and angular MISALIGNMENT are presented and close-form solutions for axial and angular stiffness are obtained. In the end we confirm accurate ANALYTICAL SOLUTIONs by comparing the finite element results and determine the most critical point in the fatigue design of diaphragms.
