According to thinking the joints of plates as elastic boundary supports to plates and by using of the method of separation of variables , betti ' s reciprocal theorem of work , the solution of dynamic equation can be deserved 運(yùn)用變分法,分離變量法,互等功定理等數(shù)學(xué)工具求解板的運(yùn)動方程,可得出彈性地基上考慮接縫傳荷能力的道面板在移動荷載下的動力響應(yīng)(解析解) 。
4 . with visco - elastic boundary of soil considered , the eigenvalue equation in frequency domain of soil dynamic equilibrium equation falls into a complex transcendental equation . in course of seeking its solution , based on argument principle and contour integral , with the aid of matlab , two numerical algorithm combined with the corresponding procedures for solving transcendental equations in a complex plane is developed by the author 4 、由于考慮了土體的粘彈性支承邊界條件,使得其動力平衡方程在頻域內(nèi)的固有值方程為一復(fù)數(shù)超越方程,為了求解該方程,筆者基于幅角原理和閉合曲線積分,結(jié)合matlab ,提出了復(fù)平面上超越方程的兩種數(shù)值解法,并編制了相應(yīng)的程序。
Furthermore , in order to improve the modeling accuracy of the whole robot structure , the elastic boundary pole with multi - restriction and the spatial lamella are study in this paper by using bem , and the boundary integral equations are set up . this lays foundations for introducing the spatial elements combined structure and the composed configure of the staff and plate , which has much application values 此外,為了提高機(jī)器人機(jī)械結(jié)構(gòu)的靜力學(xué)建模精度,本論文還對多約束柔性邊界桿件及空間板單元結(jié)構(gòu)進(jìn)行了解析研究,建立了相應(yīng)的邊界元方程,為空間板單元組合結(jié)構(gòu)及板梁合成的引入及研究打下了基礎(chǔ)。
