发动机排气歧管罩降噪分析与结构改进
For the manifold of sedan engine , the hest thermal fatigue properties can be obtained by keeping the percent of vermicular graphite at about 50 % , therefore it shouldn ' t he considered that the lowest e . g . percent limit of 50 % specified in chinese vermicular iron standard is too lower , and it is also not proper to take the v . g . percent as the basis for judging the level of production technology
摘要对轿车发动机排气歧管而言，蠕化率控制在50 %左右可以获得最佳的抗热疲劳性能，因此不能认为我国的蠕铁标准中规定的蠕化率高于50 %的要求偏低了，也不能把蠕化率的高低作为衡量工艺水平的依据。
