contact fatigue

基本解释

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-棒疲劳试验机，研究了纳米金刚石粉对钢球接触疲劳寿命的影响。
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.
经薄层硬化的T8A钢，可以获得较好的多冲接触疲劳抗力，故有可能作为凿岩机活塞用材。
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.
驾驶员疲劳驾驶是导致交通事故频频发生的主要因素之一，车载的、非接触式的、实时的驾驶疲劳检测设备是研究的主流。

接触疲劳
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.
渐开线圆柱齿轮传动的接触疲劳强度设计是以Herze理论为基础的,而Herze理论仅仅适用于一对光滑表面之间无润滑、无摩擦的静态接触,这与齿轮传动的实际状况出入较大。
