The article gives details of a device designed to measure cross-country ground profiles for use in vehicle ride simulation. The method described uses a surface profile following technique able to accept a variety of wheel sizes so that the enveloping effect of the tyres and the effect of soil compressibility could be investigated. The method of measuring absolute displacement of the wheel uses a helium-neon laser beam to act as reference level aimed across the profile being measured. An array of photocells monitors the position of the beam above the wheel and hence above the ground. The results of cross-country profiles will be analysed and described mathematically and used as input to vehicle suspension modelling. It should then be possible to predict ride characteristics and driver response. /TRRL/
