Fluid Power Laboratory

Research focuses on improving energy efficiency and efficiency of design of mechatronic systems with high power requirements, such as non-road mobile machines (NRMMs). To do this, we develop physics-based, data-driven and hybrid models that are validated with experiments at our laboratory.

Current research setups at the lab include:

  • Large-scale mobile machine infrastructure intended to validate new, more efficient system architectures.
  • Electro-hydraulic actuation coupled with multi-pressure system focusing on improving linear actuator efficiency
  • Passive and active damping systems, which reduce wear and ensure long-lasting operation
  • Hydraulic accumulator development for better component-level efficiency
  • Waste heat utilization system, which turns low waste heat into useful work.

Main challenges investigated in our research include efficiency, performance, control, price, reliability and usability tradeoffs and limitations. Main challenges investigated in our research include efficiency, performance, control, price, reliability and usability tradeoffs and limitations.  Some of the fundamental scientific questions we seek answers to include: How can we accelerate the transition to zero-emission mechatronic systems? How can we utilize generative design, ML and AI to improve design process performance and support innovation?

working hydraulics.

    “Electrification drives and enables the design of new solutions that can outperform older technologies. While components of heavy mobile machines should be as small, inexpensive, and reliable as possible, all components should also be utilized extensively to maximize space usage. My research focuses on system-level design, which involves the proper sizing and multifunctional use of all primary system components.†Topias Tyni
