热载荷蜂窝夹层板作用下固有频率预测与分析
Natural Frequency Prediction and Analysis of Honeycomb Sandwich Plate with Thermal Load
摘要
Abstract
The stress distribution and natural frequency changing of honeycomb sand wich plate is proposed in this paper with thermal load,and the natural frequency of honeycombs and wich plate is predicted according to the stress distribution.The simulation results show that the natural frequency of honeycombs and wich plate with carbon fiber skin is essentially the same with thermal load,and the constraint effect to the frequency change is very small.The frequency of honeycombs and wich plate with aluminum alloy skin with thermal load changes greatly when constraint form changes,and the frequency is essentially the same with a small amount of constraint,and the major constraint will cause the frequency decreasing dramatically.关键词
