crank axis 中文意思是什麼
crank axis
解釋
曲柄軸線-
The optimization design of the crank - connect rod mechanism was carried out. collocating the mass reasonably, adjusting the ratio ( ( 1 - f ) / f ) of the long axis to the short axis of the ellipse track, adjusting the direction of long axis to the direction where the internal - combustion engine was not sensitive to the stimulating force. all the above contribute to the max reduction of the vibration
對單缸內燃機的曲柄滑塊機構進行優化設計，合理的布置加配質量的大小和方向，對軌跡橢圓的長短軸比率（ 1 - f ） / f進行調整，將長軸方向調整到內燃機對激振力不敏感的方向，從而使不平衡力對內燃機所產生的振動最小，以某一具體的單缸內燃機為例進行了計算分析。 -
The results of analysis show that : 1 ) doi of the pin - axis errors, especially the crank - pin - axis errors, is bigger than other axis errors ; 2 ) from the calculating results of doi of the errors of the different kinematic pairs, doi of rotate - completely pairs is bigger than that of oscillate pairs ; 3 ) the forced coupler - deformations resulted from the constraints out of motion plane consist of twisting and bending deformation, and the deformations are variat
（ 4 ）首次提出了運動副誤差對平面連桿機構約束不確定性影響度的評判指標和單因素定量分析方法，得到了機構中不同運動副的不同平面內的誤差對機構性能的影響程度。本文的分析計算結果表明，平面連桿機構中的非平面約束所造成的連桿強制變形中既有扭轉變形又有彎曲變形。 -
The mechanisms and conditions for the mechanisms to adjust itself were analyzed in detail. an accurate method of analyzing for the properties of the mechanisms without overconstraints was given for the first time, we obtained the equations of self - adjusting displacement in the cylindrical pair, the allowable kinematic - pair - axis errors which enable the mechanisms realize function of self - adjustment, and the most rational arrangements of kinematic pairs for the three common four - bar mechanisms. the results of analysis show that the influences of the errors of crank - pin on the self - adjusting properties of the mechanisms are bigger than that of the other pairs
（ 3 ）詳細分析了無過約束機構能夠實現自調的機理及機構能夠實現自調的條件，首次提出了無過約束機構自調性分析的一種精確方法，得到機構自調時圓柱副中的自調位移規律和機構能夠實現自調的運動副允許誤差角以及三種常用平面四桿機構的自調結構的最適宜的運動副配置方式。
