stress-relief grooves

基本解釋

Take pin threads of NC50 drill collar as an example, Finite Element Method is used to analyze the different stress-relief grooves of pin thread connection.
以NC50型鑽鋌公螺紋作爲(wèi)研究對象，用有限元方法對加工有不同應(yīng)力減輕槽的鑽鋌公螺紋接頭進(jìn)行了分析計算。
On the basis of the actual measurement of the whole stress-time course at the relief grooves of axles for passenger cars, the stress spectrum is obtained after the rain-flow counting;
在全程實測提速客車車軸卸荷槽部位的應(yīng)力-時間歷程的基礎(chǔ)上，對其進(jìn)行雨流計數(shù)後，得到其應(yīng)力譜；
