標(biāo)題: 關(guān)于ansys14.5的空間桁架
初學(xué)ansys,各種不懂。想做一個空間桁架受力分析,然后代碼寫了,導(dǎo)入ansys后加載,實(shí)常數(shù),單元類型,材料屬性都定義了,就是不求解,也查不到錯,求大神們指教T^T) s9 \$ c0 {3 g; @+ f" x7 {
問題是這樣的:1 v$ |- ?' K( q* a% }
線L1,L9受Y負(fù)方向的均布載荷1000N/m,關(guān)鍵點(diǎn)7,15,19全約束,受重力場的影響下看它的變形和應(yīng)力。

究竟是ansys14的BEAM單元的問題還是我自己的問題,反正我就是不能用梁單元在ansys里求解。用solid95單元的話,這個結(jié)構(gòu)分網(wǎng)困難,難以計算,簡化就不求解,求給位大神指點(diǎn),小弟感激不盡T^T
