Abstract: Rollover accidents occur frequently in the process of vibroseis truck driving, which endangers the drivers and apparatus. Therefore, we first study the driving stability of vibroseis trucks to determine the limit state function of stable driving. Then, the stable driving reliability analysis of the vibroseis truck could be performed under complicated road stimulation. The analysis results show that the risk of rollover still exists, so it is necessary to install a rollover protective structure (ROPS) on the vibroseis truck. Therefore, we establish a systematic and scientific evaluation index system of safety protection and performance. Then, based on the finite element analysis (FEA) technology, we perform the dynamic simulation analysis of vibroseis truck rollover with and without the ROPS. The ROPS would play a significant role in protecting the vibroseis truck. The research results also provide scientific guidance for the similar design of vehicle anti-rollover structure in the field.
