Firstly, the hertz contact theory is used to design the export moment of the prototype ; deformation status of the flexspine under the elliptical cam wave generator action is analyzed using the column shell theory, whose boundary condition is four force action. design proposal of the wave producer put forward considering the precision theory of rolling friction transmission
首先用赫茲接觸理論對樣機的輸出力矩進行了設計;應用四力作用下的光滑圓柱殼體理論分析了在橢圓凸輪波發生器作用下柔輪的變形狀況，結合滾動摩擦副傳動精度理論提出了波發生器總體設計方案。Malachite is widely available but is mostly mined in zaire, ussr, germany, france, chile, australia, and the united states in arizona and new mexico
晶體形態常呈柱狀或針狀，十分稀少，通常呈隱晶鐘乳狀塊狀皮殼狀結核狀和纖維狀集合體。With the different loading ratio of parallel to axis and normal to axis direction, damage defects will occur bulking problem. by varying the degree of material anisotropy relative to the loading axis such as poisson ' s ratio and shear modulus, crack growth bulking strain value parallel to or normal to the loading axis is different. the parameters controlling the growth or arrest of the delamination damage are identified as the geometry and the depth of defects and radius of cylindrical etc. at last, it was investigated that the delamination damage is often induced by the tip of matrix damage under higher stress
研究結果表明:殼體筒段受軸向拉伸和內壓載荷作用時，軸向和環向載荷的比率不同，母層和子層可能發生拉伸屈曲，也可能發生收縮屈曲，或者同時發生拉伸和壓縮屈曲;母層與子層各向異性存在差異，即泊松比與剪切模量不匹配時，將使子層板的邊界上承受壓縮和剪切作用，當分層達到臨界狀態則發生屈曲，當母層與子層的各向異性差異越大，則發生分層屈曲的可能性越大;分層損傷的屈曲應變值與子層自身的彈性模量、分層子層的形狀、厚度以及圓柱半徑等因素有關。
