By using bpm , the problem is reduced from a second - order boundary value problem requiring iteration or eigenvalue analysis to a first - order initial - value problem that can be solved by simple " integration " along the propagation direction 和其他模擬方法相比, bpm將二階邊值問(wèn)題簡(jiǎn)化為一階初值問(wèn)題,減小了計(jì)算的復(fù)雜性,縮短了計(jì)算時(shí)間,降低了對(duì)計(jì)算機(jī)硬件的要求。
The six methods are as follows : the supperposition method , the state space method , the complex mode method , the direct integral method , the numerical method for solving the initial - value problem of first - order ordinary differential coupled equations with constant coefficients , and the time domain finite element method 這六種方法是:振型疊加法、狀態(tài)空間法、復(fù)模態(tài)法、直接積分法、一階常微分方程組初值問(wèn)題的數(shù)值解法和時(shí)域有限元法。
