面向电磁式可控震源车激振器总成的馈能减振研究

The electromagnetic vibrator, as the ballast, may vibrate violently with the vibration exciter during its operation, resulting in a dramatic decrease of its safety and service life and an increase in energy consumption. To address these problems, the addition of an energy regeneration suspension system to the vibration exciter assembly is proposed. Moreover, a study based on the energy generation and vibration absorption mechanism, parameter matching, and self-adaptation inverse control during the operation of the vibrator is conducted. First, the kinetic model of the vibration exciter assembly, which includes an energy regenerative suspension, is built, a physical prototyping model is developed, and the kinetic model is verified and improved through prototype tests. Subsequently, the energy generation and vibration absorption mechanism of the suspension system based on the model is explored. The performance of the suspension system in terms of vibration absorption and energy generation is analyzed, the multi-objective optimization problem of the suspension system is addressed with Kriging and the IPSO algorithm, and the parameter matching problem of the suspension system is resolved. Finally, by combining the Lyapunov theory and the suspension system, this study explores the self-adaptation inverse control system of the suspension that outputs the damping force and verifies it through a prototype test. A foundation is established based on the findings of this study and a new method of body vibration absorption and energy supply research during the operation of electromagnetic vibrators is provided. The suspension system is of great academic significance and practice application value.
