Research Interest
The main objective in doctoral research is to develop a computationally fast rotordynamics simulation tool using 3D solid elements. Simulation tool needs to be able to support multiple bearings models including active magnetic bearings (AMBs). An automatic meshing algorithm that reduces effectively unneeded degrees of freedom is needed. Nowadays, commercial solutions provide only beam element or axisymmetric modelling method without any support for AMBs. The need for 3D rotordynamics simulation tool arises when the rotor under investigation includes non-circular shapes or the rotor consist of multiple parts that need to be describes using different kind of contact models such as shrink fit contacts. By means of implementing a new computational method calculation times can be shortened significantly.
