摘要 针对高温作业专用服装各材料层温度分布问题,借助BP神经网络对假人皮肤温度与作业时间进行拟合,通过建立基于空气层、专用服装材料层和皮肤外侧温度分布的热传导偏微分方程进行求解;针对服装材料层最优厚度设计问题,构造约束条件下的适应度函数,结合遗传算法进行了寻优。综合运用了MATLAB、Excel等软件对数据进行处理并编程求解,得到了一定前提条件下各材料层随时间分布的温度数据及单层服装材料层最优厚度结论,与实际相近,验证了模型的有效性和可行性,为模型推广应用到作业服装研发领域奠定了基础。 Considering the temperature distribution of each material layer in the special clothing for high temperature operation,the BP neural network is used to fit the skin temperature and working time of the dummy,and the heat conduction partial differential equation based on the air layer,the special clothing material layer and the outer skin temperature distribution is solved.For the optimal thickness design problem of the clothing material layer,the fitness function under the constraint condition is combined with the genetic algorithm to be optimized.Using MATLAB,Excel and other software to process and program the data,the temperature data of each material layer distributed with time and the optimal thickness of the single layer of clothing material layer are obtained under certain preconditions,which is similar to the actual one,verifies the validity and feasibility of the model,and lays a foundation for the application of the model to the field of workwear research and development field.
