可控震源卡车在行驶过程中频繁发生侧翻事故，危及驾驶员和设备的安全。因此，本文首先对可控震源汽车的行驶稳定性进行了研究，确定了稳定行驶的极限状态函数。然后，对可控震源汽车在复杂路面激励下的稳定行驶可靠性进行分析。分析结果表明，可控震源汽车仍然存在侧翻风险，有必要在可控震源汽车上安装侧翻防护结构。因此，我们建立了一套系统、科学的安全防护和性能评价指标体系。然后，基于有限元分析(FEA)技术，对可控震源汽车在有ROPS和无ROPS的情况下进行了动力学仿真分析。ROPS将在保护可控震源卡车方面发挥重要作用。研究结果也为现场类似车辆防侧翻结构的设计提供了科学的指导。
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.
