Abstract: This research develops a design methodology for the vibroseis truck rollover protective structure (ROPS) and analyses its safety and protective performance with dynamics simulations. A new ROPS with the vertical anti-rolling over property is designed. For the typical field working conditions, we perform the stability study on the vibroseis truck and find its threshold function by using rollover dynamics. With the proposed protection and performance evaluation criteria, we analyse the protection performance of the new and old ROPS with finite element (FE) dynamics simulation. Then, the stress to strain, impact deformation, impact acceleration and interior energy distribution law are obtained during the process of the truck rolling over. The effect of the structure on its protective performance is also found. These analyses result in an optimal design of ROPS. The results will improve the safety of vibroseis trucks and then enhance the technology of oil and gas exploration equipment.
