Abstract
Rollover threshold limits of partially filled tank vehicles equipped with tanks of arbitrary cross-sections are estimated using a simple methodology. Overturning moment caused by the lateral liquid shift within a partially filled arbitrary tank geometry is obtained as a function of the tank shape, fill level and the gradient of the free surface of liquid. The liquid load shift computed using a set of closed-form equations, developed based on the tank shape and fill level, is compared to those obtained from a comprehensive software developed based on a numerical technique. The static rollover threshold of the tank vehicles with arbitrary tank shapes are estimated by balancing the total overturning moment against the restoring moment. The results are compared to those obtained from a kineto-static analysis of tank vehicles.
