The work aims to reduce the high vibration amplitude response of packaging trays in specific frequency bands during transportation. Based on the fixed support characteristics under the actual assembly constraints of this type of packaging tray, the modal analysis was conducted to tray structures to obtain its modal characteristics, and then the modal superposition was performed to obtain the vibration transmission results of the tray system. Next, the dynamic characteristics of packaging tray structures under different coupling conditions of T-shaped oscillator structures were clarified, and the vibration transmission results were analyzed separately. Finally, the dynamic changes of packaging trays with oscillator absorption effects were summarized for all types. By comparing the dynamic characteristics of the two structures before and after a T-shaped oscillator was added, it was concluded that the packaging tray effectively suppressed the first two resonance peaks under the premise of adding a T-shaped oscillator, which clarified the coupling effect of different oscillator structures, and effectively suppressed vibration suppression at the resonance frequency. Through the above structural simulation analysis, the dynamic characteristics and vibration transmission changes of packaging trays under the coupling mechanism of T-shaped oscillators can be obtained, providing new ideas for the design of similar packaging trays.
