摘要：
Here, aiming at the problem of vibration transmission from vibration source inside a cylindrical shell through an annular support to shell body, a piezoelectric actuator-based active/passive support vibration isolation scheme was proposed. Vibration control analysis was performed for a vibration source-active/ passive support-shell coupled system. According to Flugge shell theory, a vibration model of a cylindrical shell was established using the wave propagation method. At the same time, a vibration model of vibration source-active/passive support was established using the finite element method. Finally, the coupled system vibration model was obtained by synthesizing substructure frequency response functions. Based on the coupled system model and ideal control assumption, the controll ability of shell vibration was given in frequency domain, and the effectiveness of control was verified by using a vibration source-active/ passive support-shell test system. Simulation and test results showed that the proposed active/passive vibration isolation scheme based on piezoelectric actuator can significantly reduce broadband and line spectrum vibration of shell. © 2024 Chinese Vibration Engineering Society.
