摘　　要：针对涡轮动力仿真器现有的端面半圆线槽型甩油盘未能实现对内部循环流场的散热和润滑最大效能的问题,开展以降低最大流场温度和减弱涡流效应的槽型优化研究。提出了包括拋物线、渐开线、对数螺旋线等槽型新结构,并探讨了槽深、槽数、螺旋角系数等单一因素对流场特性的影响规律,采用正交试验法对多因素多目标的槽型结构参数进行了优化。结果表明:对数螺旋线槽型为一类更能提高润滑和散热的最优结构,利用正交试验法优化出的一组最优对数螺旋线槽型参数槽深为6 mm、槽数为10、螺旋角系数为0.4,以此设计了面向更高工况条件下的新型甩油盘结构,并仿真分析了其在典型工况下的流场特性。Owing to failure of existing semi-circular grooved sling-oil retainer in the turbine power simulator to achieve the maximum efficiency of heat dissipation and lubrication of the internal circulating flow field,the parameters’optimization research of the sling-oil retainer for reducing the maximum flow field temperature and the eddy flow effect was carried out.The new groove(including parabola,involute,logarithmic spiral,etc.)structures for the sling-oil retainer were proposed,and the influence of single factor(such as groove depth,groove number and helix angle coefficient)on the flow field characteristics was discussed.The multi-factor and multi-objective parameters were optimized by the orthogonal experiment method.The results showed that the logarithmic spiral groove was an optimal structure that can effectively improve the lubrication and heat dissipation performance,and a set of optimal logarithmic spiral groove parameters by orthogonal experiment method were represented by groove depth of 6 mm,groove number of 10,and helix angle coefficient of 0.4.Based on the results,a new type of sling-oil retainer for more harsh working conditions was designed,and its flow field characteristics under typical working conditions were obtained by the theoretical simulation.
