A C++ program is developed for composing the stiffness matrix of the temperature field, saving it in changing bandwidth method and calculating the linear algebraic function group through using the Gauss eliminating method. A module for drawing the color fringe of tire temperature field is created, which makes the result more visual. Taking the 9.00-20 cross-ply tire on CA1092 as an example, the finite element numerical simulation analysis of automobile tire 2-D steady temperature field is completed. Through comparing the result with the analysis data by ANSYS, this software is proved to be capable of the modeling, calculating and post-processing of FEA of automobile tire 2-D steady temperature field.

Within this context, four specific areas are addressed:(1) By means of finite integration technique, a new kind of the first order partial difference equation is derived from the original disperse transmission line equation of the uniform waveguide's. As it is the kind of one dimension Dirichlet's boundary problem, it is convenient for us to solve this equation from the leapfrog scheme. Because computation is carried out in one dimension, both high calculation efficiency and precision have been obtained in this method. Meanwhile, this method provide us a different selection to simulate the transient response of waveguide with non-simplical, for examples cylinder and elliptic waveguide, and avoid solving the second order equation, or using finite difference time domain to simulate a three dimension problem, sometimes the latter precision is not satisfied with the need, or low efficiency.
在这一研究内容下,主要研究四个方面的问题:(1)在完成金属波导传输线方程时域形式的基础之上,应用有限积分技术,把波导特征模式的色散传输线方程,化简为一组新的一阶偏微分方程组,该边值问题属一维Dirichlet边值问题,从而便于用蛙跳格式求解,由于是在一维中计算,该方法具有很高计算效率和精度,从而避免了以往为得到金属波导中特征模的时域响应特性,须要求解二阶方程,或用时域有限差分方法求解三维问题的方法,对于后者来说,计算有时是不准确的,或是很耗时的例如计算诸如圆波导、椭圆波导等其它复杂形状的波导。
