摘　　要：采用电磁探测技术进行深部勘测时需要收集微弱的低频信号,而隔振系统的动力学特性对信号采集至关重要。基于气压传动原理设计了一种双气室的气缸式空气弹簧隔振系统,对其刚度、频率等力学参数对隔振性能的影响进行理论分析,并基于热力学和流体力学理论建立了隔振系统的非线性动力学特性模型,并对不同横截面积的气缸隔振性能进行了分析,得到了系统在最佳隔振性能时的气缸相关参数。It is necessary to collect weak low-frequency signals when electromagnetic detection technology is used in deep survey,and the dynamic characteristics of vibration isolation system are very important to collect signals.Based on the principle of pneumatic transmission,a two-chamber cylinder air spring vibration isolation system is designed,and the influence of mechanical parameters such as stiffness and frequency on vibration isolation performance is analyzed theoretically.Based on the theory of thermodynamics and fluid mechanics,the nonlinear dynamic characteristics model of the suspension system is established,and the vibration isolation performance of cylinder with different cross-sectional areas is analyzed.The cylinder parameters are obtained when the system has the best vibration isolation performance.
