This paper employs the dynamic - static force principle to simplify the mathematical models , and employs the virtual - displacement principle and adopts the sor digital algorism to extract the dynamical performances . the solutions extracted is coincidental with the practical situations 本論文應(yīng)用了達(dá)朗貝爾原理簡化數(shù)學(xué)模型,并應(yīng)用虛位移原理和sor迭代法求解機(jī)構(gòu)的動(dòng)力特性,求得的仿真曲線與實(shí)際情況比較吻合。
Then each . cable - strut - membrane unit is analyzed by adopt the non - linear finite element analytical method . according to virtual work principle , the equation of solving is formed , from the timid displacement principle , derive and happen to ask the equation of solving . through the whole n - r method , cooperative form - finding of the cable - strut - membrane structure will be realized 然后,采用非線性有限元分析方法,對(duì)各個(gè)單元進(jìn)行分析,由虛位移原理,推導(dǎo)出求解方程,通過全n - r法迭代,實(shí)現(xiàn)索桿膜結(jié)構(gòu)的協(xié)同找形。
