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.

    Workzone safety can be economically viable
    David Crawford looks how workzone safety can be ‘economically viable’. Highway maintenance is one of the most dangerous construction industry occupations in Europe. Research from The Netherlands on fatal crashes indicates that the risk facing road workzone operatives is ‘significantly higher’ than that for the general construction workforce. A survey carried out by the Highways Agency, which runs the UK’s motorway and trunk road network, has suggested that 20% of road workers have suffered injuries from pa

    Researchers at the Volvo Group are looking into a future where trucks and buses are continuously supplied with electric power without carrying large batteries. Instead, power lines are built into the surface of the road. This could be a future solution for long-distance trucks and buses running on electricity. “In city traffic, there are currently various solutions and we are researching many others. We have field tests in progress where our plug-in buses are equipped with a battery that can be charged quic

    Personal Rapid Transit, clear benefits for European cities
    David Crawford watches the race to get the world's first PRT system up and running. To paraphrase the old joke about buses bunching, you seem to have to wait several decades for a Personal Rapid Transit (PRT) system, and then half a dozen come along together. Currently, in fact, there are well over that number of schemes for driverless electric passenger-carrying 'pod' networks at various stages of planning, design and implementation around the world. Locations range from a straight-off-the-drawing board ne
