The crash testing continues!

The end of June saw some more testing at a huge Collision Reconstruction event organised by the UK’s Institute of Traffic Accident Investigators ( ) and held at Bruntingthorpe Proving Grounds ( ) in Leicestershire.

This event has grown to be a regular event that is open to everyone and attracts an audience from across the world. Over a dozen full speed crash tests were conducted during the day involving pedestrians, cyclists, cars and even an Ambulance! Plus there were a series of low speed tests, autonomous  brake testing and HGV visibility tests. There really was something for everyone. These types of crash tests are normally held in secret for internal use by vehicle manufacturers but here everyone can video, photograph what they like and have access to the data from the crashes. The fastest test was a Mazda 6 striking the side of a Ford Mondeo at 76 mph which was spectacular!

I was here to conduct some more testing into how speedometers behave during collisions. This time all the speedometers were from motorcycles. The experiment was a bit of an experiment in itself as the instruments were attached to the car using Velcro which would hopefully allow the clusters to rip free during the impact in much the same way as motorcycle speedometers can detach in real world collisions. I am happy to report that the method worked perfectly with a clean release in every impact.

The impacts were recorded in slow motion by Ix Cameras ( ) and in their footage you can see some of the instrument clusters being released at impact amid a shower of glass.

There is a huge amount of material still to work through but I obtained some useful data and will have a better idea of how motorcycle instruments behave in crashes. Expect to see an article in a journal soon.



In other news I recently went to  the automotive supply exhibition called, Automechanika in Birmingham. It was a great day with lots to see. I found this cut away Jaguar which nicely shows the crash components of the chassis.

This photo is very useful to show where the various crash components are.
