Abstract

A linear full-car model with seven degrees of freedom was adopted for the simulation of the dynamic behavior of road tankers with a fixed tank. The vehicle is subject to selected typical road surface profiles and inertial loads due to acceleration, braking and driving on a curve. For the simulation, a Monte Carlo method is used for a sensitivity analysis of the suspension characteristics including tires and the road tanker’s CG vertical shift due to the liquid load in relation with the vehicles response to road profile. A standard deviation was assumed for the aforementioned vehicle design characteristics introduced for the simulations performed. The road tanker’s dynamic response was investigated and furthermore results were compared with a static model as proposed by UN-ECE Regulation R-111 for lateral stability. The proposed method can be used as a design tool for the prediction of road-tankers dynamic response and roll-over threshold from an early design stage.
