| Abstract: | A nonsteady heat transfer equation for car body is established in this paper quoting from the method of discretization between the disturbance and respon- dency in control theory and by way of the analysis of heat transfer mechanism for car body.The formulation of transmission function coefficient is derived and dynamic heat flux is calculated.According to the sample,the transmission func- tion coefficient and heat flux of the car body are analyzed.These results point the way out for improving the car body design and raising the thermodynamic performance of car body. |
