Abstract
The present work makes the stability analysis of the heavy tank-truck vehicles. For this purpose, the so-called Static Rollover Threshold (SRT) is used, which allows evaluating the maximum laterally inertial force applied that the vehicle can support before starting the rollover process. Additionally, this factor allows determining the maximum speed that the vehicle can develop when making a curve, thus providing greater safety for road users. Taking into account these aspects, the stability of tank vehicles with circular cross-section is studied, since for vehicles that transport liquids the stability is more critical, because it must take into account the movement of the transported fluid when it is submitted to a lateral acceleration, which can decrease the stability factor. Therefore, to determine the stability factor, a detailed analysis of the movement of the fluid as a function of the acceleration and filling of the tank is performed and the Davies method is used for the quasi-static analysis of the stability of the vehicle.
