The Studies on the Dynamics of the Double-rotors System

Based on the foundation of setting up the double-rotors system mathematical model,studied the influence of the different speeds of the double rotors to the critical speed of system.The study is divided by two parts.Firstly,through numerical emulation it shows that the speed has an important influence to the critical speed of double-rotors system with intermediate bearing.Then The result has been identified by the testing on the experimental machine.
