how can test the railway tyred wheel to determain rotate tyre on to wheel center on line or off line?
in railway wheel tyre fitting on to wheel center maybe in service tyre rotate on wheel center how can by use ndt method we determine loose or displacement tyre on wheel center on line and off line. please help me whith detail of this qestion thanck alot

Dear sir/ Madam
I am s.ketabchi, working in railway factory and i am ms student mechanicl engineering college, tabrize.iran Now i am work to complet my ms project .I want to know whether
how can test the railway tyred wheel to determain rotate tyre on to wheel center on line or off line?

Dear Mr Ketabchi

Our company, Newt International of the UK, has performed many examinations of railway wheel tread surfaces using the Lizard FGI (Field Gradient Imaging) system. Using this advanced electromagnetic method we can interrogate the surface of the tread to identify (amongst other issues such as cracking, spalls, stick slip events) the running band or work hardened part of the tread as well as the profile changes. We have performed such measurements on passenger fleets and for freight vehicles with fantastic results, ensuring a much greater level of information from the tyre surface than could ever be gleaned from visual and dimensional measurements alone.

If you would like more information please contact me or visit www.lizard.co.uk for further information. I hope that this has helped.

Best regards

Paul Bentley

Dear Mr Ketabchi

Thank you for your continued interest in the Lizard technology. I have had interest from companies in Iran recently but unfortunately have been informed by the UK Department for Business, Enterprise & Regulatory Reform (formerly DTI) that it will be incredibly difficult to do business between our countries in the current political situation. This is extremely unfortunate. If this information is incorrect or somebody believes there is a solution to this problem I would be very interested to hear from them.

Best regards

Paul Bentley

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
