In many open-loop machines, there is single-valued relationship between loading rate and stiffness during dynamic testing . 許多開路機(jī)器在動態(tài)試驗(yàn)時,加載速度和剛度之間只有單值關(guān)系。
Roller bearings , load ratings and fatigue life for 滾柱軸承額定載荷和疲勞壽命
Ball bearings , load ratings and fatigue life for 滾珠軸承額定負(fù)荷和疲勞壽命
Rolling bearings - dynamic load ratings and rating life 額定動載荷和額定壽命
The loading rate is four thousand metric tons per hour 我們的裝船速度是每小時4000噸。
