摘要:分析了与双离合变速器匹配的双质量飞轮在发动机怠速工况下，减振弹簧和次级侧传力板之间、次级侧花键和变速器输入轴之间产生敲击的机理；提出了一种将敲击能量作为评价双质量飞轮敲击异响的方法；用正交试验（DOE）的设计方法指导仿真试验，厘清了双质量飞轮各关键参数对敲击能量的影响，提出了优化基础阻尼来抑制弹簧敲击的解决措施；通过实车试验验证了敲击能量仿真试验的研究方法有效，验证了仿真试验结果、客观试验结果和主观评价之间的一致性。



Abstract:Under engine idling condition， the mechanism of rattle between damping spring and secondary side and the rattle between secondary side spline and transmission input shaft when dual mass flywheel matched with dual clutch transmission were studied. The knocking energy was proposed as an index to evaluate the rattle noise. The design of experiments （DOE） method was used to guide the simulation， and the influences of the key parameters of the dual mass flywheel on the impact energy were clarified. The solution of optimize basic friction to restrain rattle were proposed. The effectiveness of DOE simulation test was verified by experiments， and the consistency between the proposed impact energy evaluation method and subjective evaluation results was verified.
