摘要：
The dynamic property of dual-chamber solid and liquid mixture vibration isolator can be easily adjusted by changing the section area of the oil tube which connects the two chambers. An active group valve containing four branches was designed to control the flow of oil flowing between the two chambers. Dynamic experiments for the novel isolator with different apertures were performed to verify the efficiency of the active group valve. The experimental result proves that the stiffness and damping properties of the novel isolator can be effectively adjusted by actively controlling the group valve. Then, the FEBC strategy combing with various methods of identifying the base frequency of the vibrating signals were introduced. At last the semi-active control of the target isolator based on FEBC strategy was carried out experimentally. The test result shows that the semi-active system with stiffness-varying property can avoid the resonance response and improve the isolation performance. © 2018, Editorial Office of Journal of Vibration and Shock.
