Simulation Analysis of a Three-Degree-of-Freedom Low-Frequency Resonant Mixer
Source abstract
Abstract
This study aims to model and analyze the performance of a three-degree-of-freedom low-frequency resonant mixer to verify the feasibility of its design approach. Based on the completion of the device design in reference to related theories, the working performance and vibration isolation characteristics of the device at different resonance frequencies were determined through modeling and simulation. The results indicate that at the third-order natural frequency, the phase difference between the payload assembly and the vibration-isolating assembly is 180°, which counteracts a portion of the force applied to the rack, thereby demonstrating effective vibration isolation. Moreover, it is found that the phase difference between the excitation force and the excitation assembly response has a great influence on the vibration isolation effect of the equipment. The acceleration and amplitude were amplified, which facilitated efficient mixing. It has been verified that at the third-order natural frequency, the device can achieve amplification of acceleration and amplitude as well as vibration isolation. This ensures efficient mixing while reducing the impact on the external environment.
