中文拼音 [piānzhuǎngǎn]
偏轉桿
英文
deflecting bar-
By constructing the geometrical model of a certain underground single arm type pantograph and applying the translation of pantograph - head balancing bar and the perpendicular displacement of pantograph in the direction of the movement of locomotive while raising pantograph as the objective which must satisfy the demands of locomotive ' s stable current collection, this paper applied the multi - objective optimization based on the genetic algorithms to design the pantograph mechanism
摘要在建立某地鐵單臂受電弓簡化幾何模型的基礎上，根據列車平穩受流對受電弓提出的各項要求，以受電弓升弓時機車前進方向上的縱向偏移量和弓頭平衡桿的平動為目標，以受電弓正常升弓所需升弓轉矩等為約束，運用基於遺傳演算法的多目標優化技術，對該型受電弓機構進行了優化，得到了使受電弓運動性能達到最優的幾何參數。Those sensitive parameters making system have negative damping and occur self - excited shimmy are horizontal pulling lever rigidity, tire sideslip rigidity, steering gear rigidity and damping, kingpin equivalent damping, kingpin caster angle, tire drag. and wheel center distance, tire side rigidity, vehicle wheel unbalanced mass, tire vertical rigidity, and distance from kingpin center to the vertical central line plane of tire have great influence on shimmy, but they do n ' t make the system have negative damping. and horizontal pulling lever damping, suspension damping and rigidity have very small influence on shimmy
橫拉桿剛度、輪胎的側偏剛度、轉向機剛度、轉向機阻尼、繞主銷當量阻尼、主銷后傾角、輪胎拖距是影響擺振的敏感性參數，適當調節某一參數可引起系統的負阻尼，使系統產生自激擺振；輪距、輪胎側向剛度、車輪上的不平衡質量、輪胎垂向剛度及主銷延長線與地面交點至車輪平面的距離對擺振的影響也較大，但不會使系統出現負阻尼；而橫拉桿阻尼、懸架阻尼與懸架剛度對擺振的影響很小。The shaft is guided by teflon - coated bearings to protect against deflection
閥桿通過特氟隆塗敷的軸承引導，以確保不會偏轉。Non - rotating stem has close roundness and straightness tolerances and is burnished for a superior surface finish
不旋轉閥桿避免了圓度和直度偏差，並且具有相當好的表面光潔度。The disadvantageous effect should be considered when the deflection between the structural mass center and stiffness center exists
摘要結構剛度中心與質量中心偏差較大時，應考慮扭轉的不利影響，將高層建築結構等效為懸臂桿，從頂至底依次選取脫離體。In the design, gear and spline were adopted, so symmetrical movement of ( collimator ’ s ) lead gates can be achieved easily, mechanical structure became more compact. worm was adopted to adjust mirrors accurately, and deflection of mirrors can be prevented in case of the external impacts or vibrations
採用齒輪齒條結構，實現鉛門的對稱開合運動，使子系統的機械結構更為緊湊，同時提高了定位精度;採用蝸輪蝸桿調解反光鏡的角度，可以使反光鏡的調節更精確，同時可以防止在外界振動或撞擊下反光鏡發生偏轉。Because of its simplicity of the critical moment and the good precision, the solutions based on gjelsvik theory are used in the elastic - plastic phase. the ultimate load carrying capacity of box section beams are calculated considering the effect of plasticity and residual stresses
其次，運用基於gielsvik約束扭轉理論推導了箱形偏壓桿的彈性彎扭屈曲荷載，同時給出了壓彎桿在彈性彎扭屈曲的軸力和彎矩相關關系。To use valve body of an eccentric, the spheroid of an eccentric and the valve seat, then the valve lever make the rotary motion, in common path self - centering, closure process pass tighter and tighter, completely achieves the good seal, therefore the hemisphere of an eccentric valve seal performance safe ; when the valve opens or shuts, the spheroid and the valve seat completely withdraw
利用偏心閥體、偏心球體和閥座、閥桿作旋轉運動時，在共同軌跡自動定心，關閉過程中越關越緊，完全達到良好密封的目的，所以偏心半球閥密封性能安全可靠；閥門啟閉時，球體與閥座完全脫開。分享友人
