Rotor DynamicsExperimental rotating system rig

Investigation of vibrations in mechanical systems, vibration abatement, signature analysis of vibrating systems, diagnostics. Ongoing projects include the following: Detection of fatigue cracks in blades: This method is based on a bilinear stiffness model, and is applied via an acoustic excitation; Detection of machine tool wear via vibration signatures: This is part of IDMAP, an EC projects with 25 partners; Multimedia teaching of vibration based diagnostics: Development of dedicated interactive signal processing tasks; Diagnostics of gears: Gearbox diagnostics, using, in particular, the Westland database, which includes vibration measurements induced by the main power transmission of a US Navy CH-46E helicopter under different fault conditions.

MAGFLY (MAGNETIC BEARINGS FOR SMART AERO-ENGINES)

MAG FLY logoMagnetic Bearing for SMART Aero Engines, SMART is an abbreviation of (Self Monitoring, Analysis and Reporting Technology) started in January at MTU Aero Engines in Munich. The main objective of MagFly is to develop a technology for SMART Aero Engines taken into account active magnetic bearings. The consortium exists of 9 partners: MTU Aero Engines (co-ordination), Turbomeca, Mecos/traxler, The Barden Cooperation, SAMTECH, TU Darmstadt, Imperial College London, EPF Lausanne and Technion Haifa.Currently aero-engines are designed with mechanical bearing systems, which consist of ball or roller bearings, often supported by squeeze film dampers. All over the world, but particularly in the United States and in Europe, there is a drive towards greater efficiency with the ‘More Electric Aircraft’ and ‘More Electric Engines’ programmes and the forecast is that future aero-engines will increasingly incorporate mechatronic systems. One of the ideas in this direction is to substitute the current mechanical bearing system by Active Magnetic Bearings (AMBs).
The program consists of the following work packages :MAG FLY group photo

  • Design of Active Magnetic Bearings
  • Whole System Modelling
  • Whole System Design
  • SMART Machines
  • Demonstrations

MAGNET (Micro Mirror)MAGNET mirror ANSYS model

The MAGNET program is intended to provide a competitive position for Israel’s industry with regard to state of the art technologies of worldwide interest. The new technologies are to be developed in a cooperative venture between the industry and leading academic scientific research in the area and they will provide the basis for new high-tech products and processes. The Central Program involves pre-competitive R&D within a consortium that includes a number of commercial companies together with research personnel from at least one academic or research institution. The R&D focuses on new generic technologies that will lead to new generation advanced products.

Undergradute Projectsan example of a graduate student project

The Dynamics Laboratory offers undergraduate students the opportunity to undertake their annual project as part of their academic requirements. The projects are multi-disciplinary, combining precision mechanical design, dynamics, electronics, real-time signal processing and control thus, providing the students with comprehensive knowledge and experience in theoretical and practical aspects of mechanical engineering.
