通过建立湿式多片制动器对偶钢片非稳态温度场计算的物理模型、数学模型，推导了微分方程及差分方程；采用Ｃｒａｎｋ－Ｎｉｃｏｌｓｏｎ无条件稳定差分格式和Ｇａｕｓｓ－Ｓｅｉｄｅｌ迭代方法计算了对偶钢片温度场沿径向和厚度方向的分布规律，并分析了钢片厚度对温升的影响，为进一步计算应力场和热变形提供了必要前提
The differential equation and differential equation were deduced by establishing the physical model and mathematical model of wet multi-plate brake on unsteady temperature field of the even steel plate. Crank-Nicolson unconditionally stable difference scheme and Gauss-Seidel iterative method were used to calculate the temperature of the dual plate Field along the radial and thickness of the distribution and analysis of the thickness of the steel sheet on the impact of temperature rise for the further calculation of stress field and thermal deformation provided the necessary prerequisites
