摘要
本文引用控制理论中扰量与响应的离散化处理方法,通过对车体传热机理分析,建立了车体非稳态传热方程,导出了车体传递函数系数计算公式,进行传热量的动态计算.通过算例,分析了车体传递函数系数及车体传热量.这些结果又为改进车体设计、提高车体热工性能指明了途径.
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.
