摘要
文中根据工程实际的需要,提出了求解二维波动方程的一维化有限元法。该方法在相同精度的情况下在计算机存储与计算量方面都有量级上的减少,为解决大型工程实际问题提供了手段。文中叙述了一维化有限元法的基本原理,详细地推导了有关的计算公式,并与一般的有限元法进行了比较。效果是明显的。
According to the need of engineering practice the paper presents a newmethod to solve two-dimentional wave equations. For the same accuracy,the one-dimentionalized finite element method put forward here requires lessarithmetic operations anb memory of computer than the usual finite elementmethod. A systematic exposition of basic principle of the method is given andthe derivation process of calculative formulae is carefully shown. To comparethe new method with the usual finite element method was conducted, theresults of which had already demonstrated that the method being developed iseffectve.
