Abstract

System of shaft rotating machine (rotor dynamics) are the most popular machine. It is commonly used in industrial application such as in steam compressors, low-pressure and high-pressure centrifugal compressors, gas turbines and aircraft engines. Dual rotor systems are usually found in a compressor and turbine engine. In this paper, finite element method (FEM) and pseudo modal are presented for the calculation of dynamic characteristics of dual rotor systems. Single rotor system is divided into 2 elements for analytical study, 13 elements for numerical study, meanwhile dual rotor system is divided into 11 elements. A computer program is developed to solve critical speeds and mass unbalance responses using engineering software namely Matlab (R2016a). The results obtained in this investigation were closed to other previous studied found in the literature which has difference between 0.12% until 6.6%.
