  1. Lastly, with the fatigue equation, the paper establishes the fatigue stress coefficient which is used in the load stress calculation for lean concrete as undersurface of cement concrete pavement, and the structure coefficient of flexural tensile strength which is used in the flexural stress check for lean concrete as base of asphalt pavement

    利用得出的疲勞方程，建立貧混凝土作為水泥混凝土路面下面層荷載應力計算的疲勞應力系數，以及作為瀝青路面基層時，進行層底彎拉應力驗算的彎拉強度結構系數。
  2. The effect coefficient of gear tooth ( ecgt ) is an important parameter while the flexspline ' s fatigue strength is studied

    摘要輪齒影響系數（ ecgt ）是研究柔輪疲勞壽命時一個非常重要的參數。
  3. And two types of fatigue equations are put forward. according to them the fatigue stress coefficient of lcb for the concrete pavement structure and the structure coefficient of tension strength of lcb for the asphalt pavement structure are developed

    並提出了貧混凝土兩種形式的疲勞方程，據此推導了混凝土路面結構貧混凝土基層的疲勞應力系數和瀝青路面結構貧混凝土基層的抗彎拉強度結構系數。
  4. Fatigue strength coefficient decreases linearly during the cyclic course ; fatigue strength exponent increases ; fatigue ductility coefficient first goes up till the maximum value at 50 % total life, and then goes down ; fatigue ductility exponent decreases during the first half cycle till its minimum value at 50 % total life and then increases in the rest cycle course ; cycle strength coefficient and cycle strain hardening exponent both decrease during the total cycle course

    結果表明： 6個基本疲勞特性參數在循環過程中都呈顯出規律性變化。疲勞強度系數呈線性減小趨勢；疲勞強度指數呈線性增大特徵；疲勞延性系數是一個先增后降的過程；而疲勞延性指數隨循環進行由初始減小到逐漸增大；循環強度系數和循環應變硬化指數在整個循環過程中都趨于減小。
  5. 2, the friction coefficient at the pitch point is not a monotonic quantity of the rational speed or the load, instead of having a maximum value. and the value of the friction coefficient is very small, its order of magnitude only being 10 - 3. so, it is reasonable that the friction force on teeth surfaces are ignored when the gear - driven contact fatigue strength is designed

    2 、當輪齒在節點嚙合時，隨著轉速或載荷的變化，齒面摩擦系數並非呈單調變化，而是存在極值點;節點嚙合處的齒面摩擦系數很小，其數量級為10一， ，因此在做齒輪強度設計時，忽略齒面摩擦力的影響是有理論根據的。
