SIMULINK LIBRARY PROJECT FOR MODELING AND SIMULATION OF DYNAMIC PHENOMENA IN ROTATING POWER TRANSMISSION SYSTEMS

摘要

This paper presents the concept and an example of usage of Simulink blocks library with which dynamic simulation of complex systems with rotating shafts, rigid rotors, bearings and couplings, general rotating power transmission systems of any configuration can be performed. The assumption is that library is modular and expandable. The main part of the library currently being developed is rigid rotor model with 6 degrees of freedom of the static and dynamic imbalance. Other components are: block modeling the bearing with mounting stiffness, damping and inertia; linear elastic-damping element and rigid beam finite element (RFEM). Also in preparation are: block modeling shaft with Timoshenko beam elements and Rayleigh damping, block modeling clutch.
