Research of Vibration Characteristics of Group Opening Panel Structure

摘要

This paper analyzes the vibration characteristics of group opening panel structure in the ship integrated superstructure's side by using finite element software-ANSYS. The results of modal analysis of two schemes of panel structures with large openings, 2×2 openings and 3×3 openings are compared with each other. The effects of opening number and fixing the frame carrying equipment to the openings on the vibration characteristics of the group opening panel structures are studied. According to the modal test results of the group opening panel structures and the comparisons of test results and simulation results, some suggestions may be provided for the design of group opening panel structures in ship superstructure.
