Abstract

The work aims to compare and analyze the modal characteristics of different stiffened container panel structures, clarify the low-to-medium frequency modal regulation rules of container panels, and provide references for the design and optimization of related container transportation. Firstly, a conventional unstiffened container panel structure model was established. Second, its modal characteristics were solved. Then, based on the mode superposition method, ANSYS software was used to obtain the dynamic response results of different models. On this basis, an X-type stiffened container panel structure model was proposed to summarize the low-to-medium frequency modal adjustment rules of container panel structures. By comparing the dynamic response results of different container panel structures, it was found that on the basis of unstiffened container panels, the stiffened structure design could maximize the natural frequency increase by 22.2% and reduce the vibration transmission level by a maximum of 13.3%. This effectively optimized the dynamic performance of container panels and achieved the goal of low-to-medium frequency modal adjustment of container panels. Through the above structural design optimization idea, it is demonstrated that the modal frequency of container panels can be adjusted by adding stiffeners. In particular, the X-type stiffened container panel exhibits excellent dynamic characteristics in the low-to-medium frequency range, laying a solid foundation for the high stability and excellent vibration suppression of container structures in complex marine cargo transportation environments.
