Abstract: In order to reduce the harm of rollover accident of vibroseis vehicle to the cab crew's life and equipment in oil and gas exploration, rollover processes of a KZ-28 vibroseis truck with and without its rollover protective structure were simulated after establishing an index system for safety protection and performance evaluation (safety protection capability and energy absorption performance). Safety protection capability evaluation indexes include cab's safety space intrusion rate and acceleration. Energy absorption perforrnance evaluation indexes indude energy absorption rate and deformation degree of each component in the cab area. The safety performance of the rollover protective structure was evaluated and verified by the simulation results. The research shows that the rollover protective structure reduces the compression deformation of the cab is by 10%, the impact energy on the driver by 2.5%, and the invasion rate by 2.6%, and that through the cab is protective by the rollover protective structure, the invasion rate is as high as 4.2%, there is still a high risk of extrusion.
