摘要
给出了三维瞬态边界元法中系数矩阵元素的计算公式 ,针对其中的奇异性提出了解决办法 ,并推导出坦克的边界条件 ,运用边界元法求解坦克的温度场 。
A series of equations for the computation of coefficient matrix elements in 3 D transient Boundary Element Method (BEM) are presented , and schemes are provided to solve the integral singularity. The boundary conditions of a tank are also derived, then BEM is employed to solve the temperature fields of the tank. The numerical results so obtained are found to be in good accord with facts.
