“…The study and calculation of the vehicle's lateral stability is too complicated. This research model is built on the basis of some physical factors such as the oscillation model is built independently on an axis in the horizontal plane passing through the center of the wheel; the sprung mass is the mass placed on the suspension including chassis body, passengers and cargo which is referred to the center of gravity, is considered to be absolutely rigid, having two degrees of freedom and be symmetrical around the longitudinal hub of the vehicle combined with the roll model in studies, the vertical displacement ZS and the horizontal roll angle ΨS around the center of the roll; the vehicle's suspension system consists of an elastomer, a shock absorber and a number of components that help stabilize and balance the vehicle body; the unsprung mass is the mass of the components placed under the suspension, its mass of the front and rear axles, respectively, is referred to the vertical plane containing the center of gravity of the rear axle and is perpendicular to the longitudinal axis of the vehicle with vertical displacement ZU and the roll angle ΨU; the mass of the wheel is assumed to be the unsprung mass and is concentrated at the axle, ignoring the lateral deformation of the tyre [12,13] and unaffected by the road excitation.…”

Rollover accidents of passenger vehicle in the process of moving will cause danger to human life and property. Therefore, the driver needs to actively control the speed of the vehicle to avoid dangerous problems. During a steady turn, a vehicle moving at a speed of over 35 km/h will overturn, similar to when a vehicle changes lanes at a speed of over 110 km/h. The above results are evaluated based on the load transfer ratio (LTR) and the difference of the roll angle of the suspended and unsuspended mass. In this study, the author has applied D'Alembert's principle to establish the investigational differential equation system based on the dynamic model of vehicle rollover stability and used Runge-Kutta method in Matlab Simulink to simulate in time domain. The article and determined the vehicle response sensitivity at dangerous steering frequencies in the frequency domain. Research results can provide speed recommendations for drivers during driving.

“…This fluid movement can occur out of phase with the vehicle's lateral motion; somehow, it becomes resonant and leads to a decrease in the threshold of tipping stability [7]. Nguyen et al [8] analyzed the rollover stability of a circular liquid tanker truck in the case of a single-lane change. The article uses the LTR value to evaluate the vehicle's roll stability based on the rollover stability dynamics model to determine that at the liquid level height of 0.4 and 0.8 m and the movement at a speed of 100 km/h, the vehicle will roll over.…”

The enhancement of rollover stability in vehicles, particularly in liquid tank trucks, is imperative for reducing the risk of vehicular rollovers and consequent threats to human life and property. The dynamic behavior of the liquid within the tank during maneuvers such as turning or lane-changing plays a significant role in the vehicle's stability. It has been demonstrated that the implementation of a Proportional Integral Derivative (PID) controller within the stabilizer bar of an active suspension system can substantially mitigate the vehicle's propensity to roll. This mitigation is quantitatively evidenced by reductions in the lateral load transfer ratio (LTR) and the roll angle (TRA) of the suspension system. Specifically, during steady turning maneuvers, a decrease of 5.6% in LTR and 12.9% in TRA was observed for liquid levels deemed most hazardous at heights of 1.2m and 1.6m, respectively. Similarly, during lane-changing maneuvers, LTR was reduced by 6.2%, and TRA was decreased by 9.1% at critical liquid levels of 0.8m and 1.6m. These analytical outcomes were derived through the application of the Lagrange method and the quasi-static method for establishing the fluid vibration equation within the tank, supplemented by D'Alembert's principle in constructing a four Degrees of Freedom (DOFs) roll model for the differential equation system of vehicle motion. This research underpins the foundational principles for the design, manufacture, and enhancement of suspension systems, and elucidates the direction for future investigations into tank trucks transporting various liquid types.
