Why Rig Test

Vehicle Parameters Estimated from a Rig Test.

A heave input test (or combined heave and pitch tests) can be processed to provide estimates of:

A roll input test can be processed to provide estimates of roll natural frequencies and damping ratios.

A warp input test can be processed to provide estimates of overall roll stiffness for the front and rear axles.

Parameter estimates will vary from run to run, reflecting the fact that vehicles and tyres are non-linear and have properties that vary with temperature.
