EFFECT OF ANTI-ROLL BAR ON ROLLOVER THRESHOLD OF A THREE WHEELED VEHICLE

摘要

Three wheeled vehicles (TWV) are a common low costmode of transport in the Asian Subcontinent, Africa andSouth America. It is very prone to rollover in turns evenat moderate speeds. Recently anti-roll bars (ARB) havebeen installed claiming increase in rollover thresholds for(one front two rear) 1F2R wheel configuration. Rollmoment is resisted at the rear axle only. Rear Axleinstalled ARB typically increases over-steer tendency. Inthe current study a Six degrees of freedom model is usedto investigate the effect of ARB stiffness on the rolloverthreshold.
