“…The vibroseis truck is a specialized vehicle used for oil and gas exploration and, as such, plays a crucial role in the efficiency and accuracy of seismic surveys. Despite major research efforts focused on enhancing the performance of the vibrator, including investigations into its dynamic response [12], ground-coupled vibration [13], and fatigue life [14], relative little attention has been given to rollover stability and anti-rollover warning systems. It is imperative to address these aspects of the vibroseis truck technology, as they impact not only the safety of personnel and equipment but also the quality of the seismic data produced.…”

Vibroseis trucks are in danger of rollover during the steering process, which severely threatens the safety of the drivers and the equipment. Therefore, it is important to examine approaches to increase the anti-rollover ability of vibroseis trucks. According to the structural characteristics and working field of the vibroseis truck, an analysis of the influence of different factors on its rollover stability was carried out. Then, a rollover warning index and an anti-rollover warning system were established, which can achieve four levels of judgment of different driving states. A simulation analysis of the anti-rollover warning system was conducted with MATLAB/Simulink software. The results showed that this warning system could accurately determine the driving state on a flat road and a sloping road and produce four types of sound–light alarm according to different rollover states. At the same time, the vibroseis truck showed poor roll stability in the slope steering process which is more prone to rollover accidents. This study establishes a foundation for further research on the design of warning systems not only for vibroseis trucks but also for other articulated trucks.
