摘　　要：简述了某六速双离合器自动变速器的机械传动系统结构,给出了该变速器最佳动力性换挡策略,并进行了NVH仿真分析。对所开发的液压阀体总成进行的试验表明,该阀体总成的挡位平均响应时间为30.6 ms,比目前国外同类样品响应时间快。介绍了所开发的湿式双离合器结构并进行了双离合器总成试验。结果表明,双离合器1可进行精确地换挡控制;双离合器2虽然能进行换挡,但不易进行精确控制。Structure of the mechanical transmission system of a six-speed dual clutch transmission is introduced in the paper,and the optimal shifting strategy of this transmission is proposed,and NVH simulative analysis is carried out.The test with the hydraulic valve body assembly developed indicates that the mean shifting response time of this valve body assembly is 30.6ms,shorter than that of the similar product by foreign countries.DCT assembly test with the wet type dual clutch structure is carried out,the test results show that dual clutch 1 can perform accurate shifting control;while dual clutch 2,although can perform shifting,however can not easily perform accurate control.
