Special Issue Information

Dear Colleagues,

Addressing climate change by achieving country-wide net-zero emission energy supply and vehicle fleets within 30 years presents both a tremendous engineering challenge and innovation opportunity. A significant part of this energy revolution is designing structures for power generation and transportation that are lightweight, durable, power-efficient, and cost-efficient.

Vibration response is a critical element of structural design and overall machine performance. This Special Issue focuses on the role of modeling and computation in understanding the behavior of and optimizing designs for machine vibration.

Vibrating machine design and operation challenges encompass cost-performance tradeoffs and the need for adaptability to time-varying environmental characteristics. Computational techniques enable fundamental understanding and optimization of complex system vibrations. These computational approaches need to balance model fidelity with computational efficiency, sufficiently explore structural, and controller design spaces during the design stage, and reliably monitor machine health during the operation stage.

This Special Issue of Vibration is to assemble papers that encompass recent advances in computational modeling and optimization for renewable energy machines and vehicle vibration response.

The Special Issue will cover a range of topics including but not limited to the following:

Machine design applications:

  • Lightweight, efficient, and durable structural design in the presence of environmental vibrations.
  • Robust and adaptive control for vibration.
  • Emerging machine learning techniques for monitoring machine health (Industry 4.0).
  • Renewable energy and zero-emission machines.
  • Solutions for vibration mitigation or power maximization in renewable energy machines.
  • Cost analysis.
  • Experimental verification.

Modeling and computational approaches:

  • Computational methods for accurate real-time simulation of structural vibrations.
  • Model order reduction.
  • Methods for predicting lifetime performance statistics.
  • Optimization.
  • Machine learning approaches for design or predictive maintenance.
  • Digital twin.
  • Generative design.
  • Design support system.

Accurate, computationally efficient simulations enable engineers to design high-performing, cost-efficient, lightweight machines that can leverage models of predictive controls and digital twin predictive maintenance schedules. This study demonstrates a new speed-dependent eigenmode method for accurately and efficiently simulating shaft transverse vibrations. The method involves first independently computing shaft eigenmodes over a range of operating speeds, then correlating the eigenmodes across the different speeds during compilation, and finally adjusting modal properties gradually in accordance with a lookup method during simulation. The new method offers several distinct advantages over the traditional static eigenmodes and Craig-Bampton methods. The new method maintains accuracy over a large range of shaft rotation speeds whereas the static eigenmodes method does not. The new method typically requires fewer modal degrees of freedom than the Craig-Bampton method. Whereas the Craig-Bampton method is limited to modeling changes at the boundaries, the new method is suitable for modeling changing body properties as well as boundary-based changes. For this paper, a fluid-bearing-supported 10 MW direct-drive wind turbine drive shaft is tested virtually in a simulation model developed in Simscape™ Driveline™. Using the simulation statistics, this study compares the accuracy and computational efficiency of the speed-dependent eigenmode method to the traditional finite lumped element, static eigenmode, and Craig–Bampton methods. This paper shows that the new method simulates the chosen system 5 times faster than the traditional lumped mass method and 2.4 times faster than the Craig-Bampton method. Full article

The vibration on the stator core of hydrogenerators caused by electromagnetic forces is an important factor affecting the reliability and long-lasting operation of a machine. For a suitable addressment of the problem, it is necessary to accurately predict the eigenmodes and eigenfrequencies of the mechanical system. However, different results for the eigenfrequencies can be achieved depending on the applied model and material parameters. This work contributes to solving this issue by investigating the impact of different input parameters on the eigenmodes and eigenfrequencies calculated by analytical and numerical models. The results are discussed and compared to measurements performed on a prototyped 732 kVA hydrogenerator. Full article
