KeywordSatellite sailboard Sandwich panel theory Modal analysis Equivalent error Dynamic response
AbstractIn order to obtain higher equivalent accuracy in the dynamics study of satellite sailboard using sandwich panel theory, the cell size of satellite sailboard is optimized. By comparing the changes of modal frequency equivalent errors of different structures, the equivalent accuracy of satellite sailboard structure is the best when the wall thickness is 0.02 mm and the wall length is 6 mm. The section size parameter with the smallest equivalent error is applied to the honeycomb sandwich plate structure of satellite sailboard. By comparing the modal analysis results of the equivalent theoretical model with the modal test results, the modal frequency equivalent errors are within 11% and the fundamental frequency error is as low as 0.1%. The equivalent theory can be well applied to the simulation of dynamic response of honeycomb sandwich panels of this size, which provides a new verification method for the rational application of equivalent theory in honeycomb structures and a new reference for the subsequent design and research of honeycomb sandwich panel.
