The Machine Dynamics lab at LUT University focuses on advancing the field of machine dynamics and design, with a particular emphasis on rotating machines and rotordynamics. Our research encompasses a broad spectrum of topics aimed at enhancing the performance, reliability, and efficiency of rotating machinery. Through modeling, simulation, analysis, and experimental methodologies, we strive to address critical challenges in modeling and vibration analysis, fault diagnosis, and the development of novel design strategies to improve machine lifespan and operational safety.
Our team collaborates closely with industry partners and academic peers to push beyond the state-of-the-art in machine design and dynamics, contributing valuable insights and innovations to the field. Our objective is to advance the development of modeling and experimental methodologies that facilitate the shift towards a carbon-neutral society. This involves innovating efficient solutions for energy conversion machinery, contributing significantly to sustainable solutions.
