The performance influence of sinking degree and radial clearance change of the cooling fan and the auxiliary member and the commonly used top ring structure in the arc bending plate fan are analyzed. 在风扇风室模型内对冷却风扇与辅助部件的沉入量和径向间隙变化对性能影响进行了分析,并将圆弧弯板风扇常用的顶环结构对风扇性能影响进行了仿真分析。
Furthermore, based on the static auxiliary graph, the original time dependent problems can be converted to an equivalent generalized arc routing problems, and we theoretically prove the equivalence between the original and the after-transformation problems. 进一步基于图转换后的静态辅助图,把原始时间依赖问题转换为静态图辅助图上的广义弧路由问题,并从理论上证明了转换前后问题的等价性。
