摘要
给出考虑温度影响的弹翼模态特性有限元分析的一般理论 ,采用I DEAS软件对常温情况和考虑温度情况下某试验弹翼的模态特性进行有限元分析 ,并进行了常温下弹翼的模态试验。研究表明 ,温度对弹翼模态特性具有较大影响 ,其主要表现形式是使其固有频率下降 。
Providing modal analysis theory of solid missile tail with consideration of the effect of high temperature. Using I DEAS software carries out a modal analysis of experimental solid missile tail with consideration of the effect of high temperature. Comparison with the results under normal temperature condition shows the effect of the high temperature on solid missile tail is notable. The high temperature makes the natural frequencies of missile tail descend, but the modal shapes almost keep unchanged.
