Uncontrolable oscillation at lower speeds (< 10KMPH) in Front Wheels in Lateral Direction, Where as the oscillations disappear above 15KMPH

ilapakurti Venkata Naga over 5 years ago

My ADAMS Car Model sets up an uncontrollable oscillation at lower speeds (< 10KMPH)

The vehicle is Front Engine Front wheel driven type

Simulation: 10KMPH Mainitain on Plain road

The oscillation is observed in Front Wheels

The Oscillation is missing above 15KMPH

I have checked all the bushes for Self excitation warning. Nothing

Power train is connected properly to the drive shafts and drive shafts are properly attached to the spindle.

Solver Setting Used: GSTIFF/I3

SI2 setting is giving an acceptable result, but I am wondering if I am missing something in modelling. If anybody else has encountered any such problem, please guide.

I am also facing same problem while running my heavy truck model over twist track. I am using LatPth, P and D gain equal to zero and I gain 0.1

The issue disappeared on flat road but it occurs when running on durability tracks such as twist track, corrugated tracks etc. Please help
