摘　　要：为了实现多活塞螺栓的协调装配,提出一种多活塞螺栓装配工艺的优化方法,将交叉耦合控制方式应用在多活塞螺栓协调装配过程中。交叉耦合协调装配控制方法的运用,完成了对钢顶铝裙组合活塞的轴向预紧力、活塞螺栓的扭矩及角度定位多变量目标的智能装配控制。经实际生产验证,系统成功地解决了一类多活塞螺栓在装配过程中相互难以协调控制的问题,提高了机车柴油机活塞螺栓的整体装配控制精度和装配效率,保证了内燃机活塞的装配质量和可靠性。To realize the coordinated assembly of multi-piston bolts, a process optimization that applies a cross-coupling control in the process of coordinated assembly was proposed for the assembly of multi-piston bolts. By the application of cross-coupling control in coordinated assembly, the intelligent control of assembly of steel crown and aluminum skirt composite piston with multivariable targets of axial pre- tightening force, piston bolt tightening torque and tightening angle position was achieved. Verified by actual production, the cross-coupling control can successfully resolve the question of coordinated control of multipiston bolts in assembly, thus improving the control accuracy and assembly efficiency of piston bolts and ensuring the assembling quality and reliability.
