Printer Packaging Scheme Based on Logistics Transportation Environment

The work aims to study the protective performance of printer logistics packaging scheme for the printer during transportation process. Firstly, the random vibration test of the whole package of the printer was carried out to simulate the road condition of highway transportation, and the response acceleration spectral density curve of the product was obtained. Then, the 3D model for the logistics package of the printer was established. The Random Vibration analysis module (Random Vibration) in the finite element software Ansys Workbench was used for the Random Vibration simulation analysis on the whole to obtain the response acceleration spectral density, the total displacement, the stress in each direction and equivalent stress, etc. The response acceleration spectral density obtained from the simulation was compared with the experimental results, and its change trend was consistent. This verified the reliability of the simulation and that the current printer packaging scheme had good protection performance. The printer''s overall packaging solution satisfies the protection requirements for highway logistics and transportation, and provides a method for verifying the reliability of logistics transportation packaging solutions.
