Łukasz Breńkacz designs and makes calculations of bearings and rotating machinery. He is interested in vibration-based health monitoring of bearings. At work, he uses numerical methods and performs experimental research. For several years, he has been dealing with the subject of rotor dynamics related to the selection of bearings for high-speed microturbines. His research interests include hydrodynamic, gas, rolling and foil bearings. He is an author or co-author of several expert opinions and about 60 scientific publications. He also participated in 9 research projects, in two of them as a project manager. Currently, he is a project manager in the project entitled “Active foil bearing with variable dynamic properties”, which is financed by the NCBR.
He is a mechanical engineer who designs various devices, usually laboratory test rigs. He is also an IT engineer who writes his own calculation codes when he needs them, for example for signal processing. In his doctoral dissertation, he investigated the properties of hydrodynamic bearings, i.e. stiffness and damping coefficients determined by experimental and numerical methods. In his professional work, he performs FEM (Finite Element Method) analyses as well as numerical and experimental modal analyses (for instance using Abaqus and LMS Test.Lab (now Simcenter Testlab)).
