论文摘要

非线性部分微分方程(PDE)完成了许多领域中许多现象的建模,例如数学,物理,化学,工程,生物学和天文学。双曲线电报方程是其中之一,它描述了结构(例如建筑物,梁和机器)的振动,并且是原子物理基本方程的基础。有几种分析方法和数值方法用于求解电报方程。分析解决方案认为以良好的形式构建了问题并计算确切的分辨率。它还有助于从准确性和融合方面理解问题的答案。这些分析方法具有准确性和收敛性的局限性。因此,提出了一种新的分析近似方法来处理本文的约束。该方法在其派生中使用Taylors的系列。所提出的方法已用于求解具有初始条件的二阶双曲方程(电报方程)。提出了三个示例,以检查该方法的有效性,准确性和收敛性。该方法的溶液也与通过Adomian分解方法(ADM)和同型分析方法(HAM)获得的解决方案进行了比较。该技术易于实施并产生准确的结果。特别是,这些结果表明,就准确性和收敛而言,所提出的方法比其他方法更好,并且比其他方法更好。

The modeling of many phenomena in various fields such as mathematics, physics, chemistry, engineering, biology, and astronomy is done by the nonlinear partial differential equations (PDE). The hyperbolic telegraph equation is one of them, where it describes the vibrations of structures (e.g., buildings, beams, and machines) and are the basis for fundamental equations of atomic physics. There are several analytical and numerical methods are used to solve the telegraph equation. An analytical solution considers framing the problem in a well-understood form and calculating the exact resolution. It also helps to understand the answers to the problem in terms of accuracy and convergence. These analytic methods have limitations with accuracy and convergence. Therefore, a novel analytic approximate method is proposed to deal with constraints in this paper. This method uses the Taylors' series in its derivation. The proposed method has used for solving the second-order, hyperbolic equation (Telegraph equation) with the initial condition. Three examples have presented to check the effectiveness, accuracy, and convergence of the method. The solutions of the proposed method also compared with those obtained by the Adomian decomposition method (ADM), and the Homotopy analysis method (HAM). The technique is easy to implement and produces accurate results. In particular, these results display that the proposed method is efficient and better than the other methods in terms of accuracy and convergence.
