轨道发射器模拟小车发射中轨道会产生大量的焦耳热和摩擦热,冷却散热措施是系统设计的重要内容之一。在深入剖析冷却效果和绝缘性能与措施中的参数变量喷水时间、喷气压力、喷气时间、喷水流量的变化趋势和敏感度的基础上,引入层次分析法评价优选出了表面喷淋冷却综合效能最优方案。为减少主观因素的作用,利用基于AHP-模糊数学理论对该方案进行检验,进一步证明了该方案是最优方案的判断。
The rail generated a large mount of joule heat and friction heat when the simulation car of rail launcher was launched.The cooling measures were one of the important contents of the system design.The change trend and sensitivity of the cooling effect and insulation performance of the parameters such as spray time,jet pressure,jet time,spray flow were fully analyzed.The optimal program of overall integrated-performance was credited after the introduction of AHP method.In order to reduce the influence of subjective factor,the scheme was tested using the AHP-fuzzy mathematics,further proving the scheme was the optimal solution
