摘要
可控震源是物探领域的重要设备,其在低频段的隔振性能不理想,在一定程度上影响了勘探的效果。以KZ-28型可控震源车为研究对象,建立了负刚度隔振系统,通过降低刚度提高原隔振系统在低频段的隔振效率,并通过仿真验证该系统可以应用于可控震源车隔振。将负刚度系统引入可控震源车实物模型,进行了隔振效果测试。结果表明,该负刚度隔振系统能将提高隔振效率提升15%以上。负刚度隔振系统应用于可控震源车具有可行性,为后续工程应用奠定了基础。
Vibroseis is an important equipment in the field of geophysical exploration. Its vibration isolation performance in low frequency band is not ideal, which affects the exploration effect to a certain extent. In this paper, KZ-28 vibroseis vehicle is taken as the research object, and the negative stiffness vibration isolation system is established. By reducing the stiffness, the isolation efficiency of the original vibration isolation system in low frequency band is improved. The simulation results show that the system can be applied to the vibration isolation of vibroseis vehicle. The negative stiffness system is introduced into the vibroseis vehicle model to test the vibration isolation effect. The results show that the negative stiffness vibration isolation system can improve the isolation efficiency by more than 15%. It is feasible to apply the negative stiffness vibration isolation system to the vibroseis vehicle, which lays the foundation for the follow-up engineering application.
