ROAD TANKER OVERTURNING--WITH AND WITHOUT LOGITUDINAL BAFFLES

VALTNINGSSTABILITET FOER TANKFORDON--MED OCH UTAN LANGSGAENDE SKVALPSKOTT

A contributing factor to the overturning of heavy vehicles carrying liquid load is the load movements in the tank combined with vehicle roll. The present report examines how a specific vehicle with elliptic tank cross section will increase its stability against overturning when the tank contains longitudinal walls or baffles to reduce the liquid lateral movements. The investigation is based on a mathematical computer model of the vehicle with 2 degrees of freedom combined with a physical model of the tank and liquid. The results show that vertical walls increase the resonance-frequency of the load from about 0.5 Hz to higher and probably more uncommon frequencies. This resonance-frequency increase will not occur if the tank is supplied with a horizontal baffle. In fact, this baffle reduces the load movements only when the baffle is near the liquid surface. /Author/
