摘　　要：为获得满足使用要求的变矩器性能,利用CFD软件对液力变矩器内流场进行了三维流场数值计算和分析,在此基础上,对原有变矩器作改型设计,以期得到分布合理的内流场,从而使改型后的变矩器具有更优的外特性.数值仿真表明,变矩器原型涡轮流道内存在的局部高压区和逆压区在改型后被消除,流场分布更合理.外特性试验结果显示,改型后的变矩器性能大大提高,完全满足设计要求,改型设计效果良好.Based on the three dimensional flow simulation and analysis, amending design of torque converter was made to obtain fine internal flow field and better performance. Result from flow simulation shows that the high pressure region in turbine flow field was eliminated after amending design. Test result shows that the performance of torque converter was improved by the design.
