Based on the equation of general frequency response functions ( gfrf ) of the non - linear dynamic systems , in this paper , the difference is applied to detect the non - linear element positions in a complex structure 本文在研究非線性系統(tǒng)廣義頻率響應(yīng)函數(shù)表達(dá)式的基礎(chǔ)上,導(dǎo)出一種適用于復(fù)雜結(jié)構(gòu)中非線性元件位置分布的判斷方法。
Then bar element ' s tangential stiffness matrixes are deduced , which is based on the finite element method . the geometrical nonlinearity and material nonlinearity are both considered in the non - linear element stiffness matrix 利用有限元方法,對(duì)網(wǎng)殼結(jié)構(gòu)進(jìn)行了幾何和材料非線性分析研究,推導(dǎo)了空間鉸接桿單元的幾何和材料非線性的剛度矩陣。
In this paper , the boundary problem of laplace equation is changed into the variational equation which is equivalent to the boundary integral equation . using linear element , it is solved by galerkin boundary element method 本文把laplace方程的邊值問(wèn)題轉(zhuǎn)化為邊界積分方程后,通過(guò)與邊界積分方程等價(jià)的變分形式,采用線性單元,利用galerkin邊界元方法求解。
In an electric circuit, a linear element is an electrical element with a linear relationship between current and output voltage. Resistors are the most common example of a linear element; other examples include capacitors, inductors, and transformers.
