Abstract EN
The stable operation of a high-speed rotating rotor-bearing system is dependent on the internal damping of its materials.
In this study, the dynamic behaviours of a rotor-shaft system with internal damping composite materials under the action of a temperature field are analysed.
The temperature field will increase the tangential force generated by the internal damping of the composite material.
The tangential force will also increase with the rotor speed, which can destabilise the rotor-shaft system.
To better understand the dynamic behaviours of the system, we introduced a finite element calculation model of a rotor-shaft system based on a 3D high-order element (Solid186) to study the turbocharger rotor-bearing system in a temperature field.
The analysis was done according to the modal damping coefficient, stability limit speed, and unbalance response.
The results show that accurate prediction of internal damping energy dissipation in a temperature field is crucial for accurate prediction of rotor dynamic performance.
This is an important step to understand dynamic rotor stress and rotor dynamic design.
