“…In the study [8], the authors also used a 7 DOFs dynamic model to analyze the factors affecting the roll stability of the vehicle, including vehicle speed, load, the height of the vehicle's center of gravity and nonlinear Pacejka tire model combined with Fishhook steering angle, the analysis results show that the tire track, suspension parameters and road excitation affect the vehicle's rollover stability. Some authors also study for Heavy Articulated Vehicles (HAV) as in the study [9], applying the Davies method for a three dimensional trailer dynamics model which to evaluate based on the static rollover threshold (SRT) factor, the author determined the SRT factor can reduce or increase by that the vertical and lateral displacement, and increase with the longitudinal displacement of the car. Besides determining the factors affecting roll stability, the authors [10] also tested on 3-wheel vehicles (TWVs), which are built to save fuel and are cheap, it is necessary to check the stability of the vehicle in the case of a 39 degree tilt test, the test shows that the vehicle is stable when increasing the wheel track and decreasing the seat height.…”

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.

“…Many studies have been conducted to investigate the dynamic roll performance of engineering vehicles. Moreno et al 1 established a non-linear dynamic model and analyzed the influence of load analysis on the static tipping threshold. Li et al 2 established a 7-degree-of-freedom (DOF) dynamic non-linear model based on the Lagrange equation and studied roll stability on the articulated wheel loader considering the load distribution.…”

A 16-degree-of-freedom non-linear roll dynamic model is developed for an articulated engineering vehicle considering non-linear road excitations and non-linear characteristics of vehicle structures. In addition, a variable step-size numerical method is proposed to solve the non-linear dynamic model. The proposed numerical method can improve the calculation accuracy and the computational stability. Through the proposed dynamic model, an equation is derived considering time-varying tire load characteristics to reflect the roll stability of an articulated engineering vehicle. Using the proposed roll stability equation, the driving stability can be effectively evaluated for an articulated engineering vehicle with different system parameters. The analysis results show that the roll stability decreases significantly with the increase in vehicle speed, centroid height of engineering vehicle, or lateral slope angle. The influence of vehicle speed and lateral slope angle on roll stability is greater than that of the centroid height of engineering vehicle. When steering on the road with a lateral slope angle, the roll angle and the lateral load transfer ratio curves fluctuate with time. As the lateral slope angle increases, the fluctuation is stronger. Overall, the proposed model can accurately evaluate the roll stability of a driving articulated engineering vehicle and accurately determine the unstable tilting of an articulated engineering vehicle.
