【導(dǎo)讀】先選擇一個近似彎曲應(yīng)力的分布，然后通過一體化。該方法適用于解決靈活滑塊曲柄機(jī)構(gòu)問題，制定的依據(jù)。過彈性橫向撓度構(gòu)成的軸向負(fù)荷的鏈接來工作。梁元模型以翻轉(zhuǎn)運(yùn)動為基。礎(chǔ)，結(jié)果表明以應(yīng)力和位移為基礎(chǔ)的有限元方法。方法得到了應(yīng)用和發(fā)展。Veubeke和Zienkiewicz[1-2]首先對應(yīng)力有限元素。之后，這種方法被廣泛用于解決應(yīng)用程序中的問題[3-5]。外，還有各種書籍提供更加詳細(xì)的方法[6，7]。因此，有必要分析靈活的彈塑性動力學(xué)這一類的問題，而不是分析。靈活的機(jī)制是一個由無限多個自由度組成的連續(xù)動力學(xué)系。并且通過能有效預(yù)測橫向振動和彎曲應(yīng)力的五次多項式建立了一個。改進(jìn)后的方法首先選定了假定應(yīng)力函數(shù)。合假定應(yīng)力函數(shù)得到橫向位移函數(shù)。當(dāng)然，這種方法能解決沒有強(qiáng)制制約。因素的應(yīng)力集中問題。目的是通過這種方法提高準(zhǔn)確性，該系統(tǒng)存在的問題也可。主要是因為不連續(xù)量的產(chǎn)生以及間離散分。是元件的載荷向量。提出解決曲柄滑塊機(jī)構(gòu)問題的方法，變量是曲率的節(jié)點(diǎn)。
