[請益] ANSYS元素是否影響自然頻率
各位大大好
我目前在模擬夾心板材料(外面是面元素 心材是體元素)
要做自然頻率比較
要做到非常接近才會繼續延伸其他研究
目前卡在
我原本使用一次元素:SOLID185 和SHELL181配合
但因為自然頻率分析不出和paper一樣的結果
但因為檢查所有參數都確認過沒有錯
後來試著改成二次元素:SOLID186 和SHELL281配合
結果發現 兩個分析的結果不一樣@@
而且差蠻多的
雖然還是跟結果不一樣XD
想請問一下是元素設定不同會有這麼大的影響嗎?
還是是我可能程式碼又哪邊有錯……
自然頻率比較這邊卡好久覺得好灰心QQ
還有順便問一下實體元素和殼元素做簡支撐的邊界條件要如何設定
謝謝大家
