摘要: 路面结冰易于导致交通事故的发生,因此提出一种路面暖气垫融冰法。为了获得最佳的融冰效果,以固定体积暖气垫为研究对象,将暖气垫工作表面的融冰速率和融冰均匀度作为评估指标,以暖气垫长度、厚度和通路间距为优化参数,通过热流场仿真分析,采用均匀设计响应面法得到优化目标与结构参数间的函数关系,运用遗传算法进行多目标优化得到非劣解集,采用理想点法TOPSIS从中选出最优解,得出结论:当通路直径取20 mm时,最佳参数组合为通路间距48 mm、暖气垫厚度68 mm,横向边长可根据工程应用确定。Abstract: The ice formation on a road surface can easily lead to traffic accidents.Therefore, a method of melting ice with a heating pad using for road is proposed.In order to obtain the best ice-melting effect, a heating pad whose volume is fixed is taken as the object of study.The melting speed and melting uniformity on the working surface of the heating pad are taken as the evaluation indicators, and the length, thickness and gas path spacing of the heating pad, are the optimization parameters.The thermal flow simulation analysis is performed by means of a uniform design response surface method to obtain the functional relationship between the evaluation indicators and the structural parameters.The genetic algorithm is used for multi-objective optimization to obtain a non-inferior solution set.The optimal point method TOPSIS is used to select the optimal solution.It is concluded that when the diameter of the gas path is 20 mm, the best combination of parameter values is 48 mm between the gas paths, 68 mm for the thickness of the heating pad, and the lateral length can be determined according to engineering application.
