contact fatigue

基本解釋

Effects of nano diamond particles on contact fatigue life of steel ball were evaluated on a self-made ball-rod contact fatigue tester.
利用自制的球-棒疲勞試騐機，研究了納米金剛石粉對鋼球接觸疲勞壽命的影響。
Through the shallow hardening treatment, the steel T8A can have better contact-fatigue resistance to the repeatedimpactload-test and can be used for making the piston of rock drill.
經(jīng)薄層硬化的T8A鋼，可以獲得較好的多沖接觸疲勞抗力，故有可能作爲鑿巖機活塞用材。
Driver fatigue driving is a major factor that causes frequent traffic accidents frequent. Vehicle, non-contact, real-time driving fatigue testing equipment is the main research directions.
駕駛員疲勞駕駛是導致交通事故頻頻發(fā)生的主要因素之一，車載的、非接觸式的、實時的駕駛疲勞檢測設(shè)備是研究的主流。

接觸疲勞
The contact fatigue strength design of involute cylinder gearing is based on Hertz theory. However, this theory is only suitable for the frictionless, static dry contact between two smooth surfaces, which is inconsistent with the reality of industrial gear drive.
漸開線圓柱齒輪傳動的接觸疲勞強度設(shè)計是以Herze理論爲基礎(chǔ)的,而Herze理論僅僅適用於一對光滑表麪之間無潤滑、無摩擦的靜態(tài)接觸,這與齒輪傳動的實際狀況出入較大。
