Crash test
Hello. Due to strict regulations in Norway, we need a crach test to register a Locost for the road.
Has anyone heard about someone performing crash tests ?
Has anyone pictures of crashed locosts?
Has anyone performed fem analyzis of the chassis ? (Both under duty load and under crash)
I hope there is someone of you who can help.

Get a Volvo and stick a locost badge on it, that's probably the closest your gonna get .....

Wasn't it Norway that MK were shipping chassis' to?
I know that some of their chassis design was done for reasons of crash testing so maybe it was to pass this particular test.
Others will probably know more about this...
HTH,

Silly suggestion. How familiar is the Norwegian police with the likes of Westfield / Caterham and several other manufacturers who would have this
data?

I investigated this kind of problems for months in my country.
The best thing you can do is register the car in UK and export to your country.
This will save you a lot of troubles.
I have to take this way too, in my country is virtually impossible get a locost (or other kit cars) legal.

I have performed an finite element analysis of the chassis. The basic book chassis has a tosional stiffness around 1100 (alloy floor book chassis) to
1400 (all panels welded in steel and welded on scuttle) ftlbs per degree of twist.
This is how to double the chassis stiffness, reduce the weight and reduce the number of tubes.
Weld in a steel panel between tubes E and LD. Add a V brace from the midle of tube LC to the ends of tube LD. Add side diagonals between tubes FU1/FU2
and tubes LA/LB. Check that these extra tubes do not interfere with the steering or radiator arrangements.
Remove tubes h,g,c,d,i,j and the rear k arch. leave the front tube k arch in place. Make the tunnel from welded in 1.2mm (18 gauge) steel closed in on
both sides, the top and the bottom. Make all the sheet steel panels on the chassis except for seat belt and suspension mounts from 1.2mm (18 gauge)
steel.
Add two extra tubes from A1/A2 where they join TR5/6 to tubes a and b. These new tubes should be in line with the front of the seats. This reinforces
the floor which may distort when made of thinner steel.
If possible double up tube R on the opposite side of the chassis.
I have not performed any kind of crash analysis on the lowcost chassis using fea. This kind of analysis is much more complex than simple torsional
analysis and there are many different kinds of accident to consider.
Good luck with your car. I hope these comments are helpful.
