中文拼音 [rèpíláo]
熱疲勞
英文
heat fatigue; thermal fatigue熱疲勞斷裂 thermal fatigue fracture-
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
摘要對轎車發動機排氣歧管而言，蠕化率控制在50 %左右可以獲得最佳的抗熱疲勞性能，因此不能認為我國的蠕鐵標準中規定的蠕化率高於50 %的要求偏低了，也不能把蠕化率的高低作為衡量工藝水平的依據。Thermal fatigue behavior of niobium microalloyed h13 steel
13鋼的熱疲勞行為The thermal properties of medium silicon - molybdenum vermicular iron are about three times of that of normal vermicular iron, so it is an ideal material for producing manifold
中硅鉬蠕鐵的抗熱疲勞性能為普通蠕鐵的3倍，因而是製造排氣歧管的理想材料。Flame tube in aircraft engine undergoes high temperature and high speed airflow washing. a hypothesis was suggested, which takes the transient heat transferring as the main reason to the cracking and damage on flame tube. finite element method was adopted to simulate the thermal fatigue and the hypothesis was reproduced
發動機火焰筒的熱疲勞損傷是導致火焰筒失效的主要原因，本文提出了一種火焰筒熱疲勞損傷假設，認為火焰筒熱疲勞損傷不是由於發動機的運行和停車時冷熱溫度循環造成的，而是發動機啟動時瞬態溫度傳導過程中材料循環塑性變形的結果，利用該假設結合有限元計算模擬了火焰筒產生疲勞損傷的原因。Thermal fatigue testing method for hot die steel
