New way of ‘harvesting’ energy from shock absorbers ‘could benefit transport industry’

A UK university student researcher has made a breakthrough by designing and constructing a new system which ‘harvests’ the energy generated by a vehicle’s shock absorbers and feeds it back into batteries or electrical systems such as air conditioning.

A UK university student researcher has made a breakthrough by designing and constructing a new system which ‘harvests’ the energy generated by a vehicle’s shock absorbers and feeds it back into batteries or electrical systems such as air conditioning.

Ruichen Wang from the University of Huddersfield carried out the project to obtain his doctorate at the University and has published his findings.  The article, Modelling, Testing and Analysis of a Regenerative Hydraulic Shock System, provides a summary of current progress in the field of vehicle energy harvesting and a detailed account of the theory and the practical development of his device, designed for installation in a heavy good vehicle.

After working on the mathematics, computational analysis and design of his device, Dr Wang constructed his full-size, ready-to-test prototype, which his supervisor Professor Ball says is a realisable application for energy recovery from a typical road vehicle.
 
Harvested energy can be used for any auxiliary purpose in a vehicle, said Professor Ball, and in hybrids it could recharge the electric motor.

The next stage is to work with an industrial partner to install and test Dr Wang’s system in a road-going vehicle.  But the technology has a wide application and there is every possibility that it could be adapted for rail vehicles, especially as Dr Wang has taken up a full-time research post at the University of Huddersfield’s Institute of Railway Research (IRR).

According to Dr Paul Allen, who leads the IRR’s Centre for Innovation in Rail, the IRR is now exploring how energy harvesting and modelling techniques can be applied to developing low-cost self-health monitoring dampers for railway vehicles, a project which already has two industrial partners.

    David Crawford reviews developments in temporary ITS. Widespread take-up of technologies such as Bluetooth and wi-fi are encouraging the emergence of more sophisticated, while still cost effective, ITS responses to the traffic issues posed by temporary road situations such as work zones and special events. Andy Graham of traffic solutions specialists White Willow Consulting says: “A machine-to-machine radio link is far easier and cheaper than reading characters on a plate.” There can be other plusses.

    A major initiative in managing numerous transport networks as a single system has moved into a significant phase with design of sophisticated new ITS systems. Jon Masters reports. Detailed design work is under way on two pilot projects pursuing a common principle – that transportation can be made more efficient or effective if the various networks and modes of travel are managed as a whole system. This is the central tenet of the US Department of Transportation’s (USDOT) Integrated Corridor Management (ICM)

Collisions between police cars, ambulances and fire crews as they reach intersections at the same time, with equal priority given by all signals set on red, are as serious as they sound absurd. For emergency teams and those in need of their help, the consequences are dire. The solution could come from application of connected veh
