The throw of the crankshaft , i . e . the distance between the main journal and the big end centers , controls the length of the stroke 曲轴的摆幅,即在主要曲颈和连杆大头末端中心之间的距离,控制着冲程的行程。
We are one of the biggest end user of tantalite and columbite . we need the ores at the long - term . if you have the ores to sell , please contact us instantly 我们是中国最大的使用钽铌矿公司之一,我们长期需要钽矿和铌矿.如果你有这些矿石,请直接联系我们
In the simulation , the mpc technique of msc . nastran is used to simulate the mechanical behavior of contact between the interfaces of piston pin and bearing of small end , crankpin and big end bearing , connecting rod body and bearing cap ; also constraints are applied to the connecting rod reasonably 分析中采用了patran中的多点约束( mpc )技术,有效地模拟了活塞销与小头孔内表面、曲柄销与大头孔内表面以及连杆体与大头盖接触面的力学接触状态,并对连杆进行合理的约束。
