摘要
将人体热调节柱状模型和手的多节段模型结合起来,建立了更完整的人体热调节模型。利用有限元方法对人体热调节数学模型进行了数值求解,并设计试验证明了模型的正确性。结果表明: (1)当取合适的血流量时,实验值和计算值的变化趋势一致,且手部温度稳定时,血流量都在确定的范围内;(2)血液流量是手部温度场变化的主要因素,人体组织和动脉入口温度对手部温度影响较小。
A more integral human thermal model was built by combining the human thermal cylindrical model and the manual poly-segment thermal model. Finite Element Methods（FEM） were utilized to solve body thermal model and the experimental results proved its rationality. The results show： （1） the experimental results are consistent with calculated value when the suitable blood flux is taken in calculation and blood flux is in certain range when manual temperature is stable, （2） blood flux is mainly the factor on the change of manual temperature field, and body organize temperature and intake artery blood temperature have little affect on the hand temperature.
