实现螺栓联接给定预紧力的有效方法西安交通大学张宏浩，牛锡传，王文生在螺栓联接中，装配时要适当预紧，以防止结合面受外力时发生松动。这是保证联接强度的前提。设计中，可通过对螺栓联接的受力分析、确定预紧力。尤其象发动机连杆的大端联接螺栓、汽轮机转子联轴器联... An effective way to achieve the pre-tightening force of bolt connection Zhang Honghao, Niu Xi Chuan, Wang Wensheng of Xi’an Jiaotong University In the bolt connection, the assembly should be properly pre-tightened to prevent loosening of the joint surface by external force. This is to ensure the strength of the premise. In the design, the preload can be determined by the force analysis of the bolt connection. Especially like the engine connecting rod big end connecting bolt, steam turbine coupling ...
