摘　　要：静偶分离摆架是双面立式动平衡机的关键技术。在分析传统立式动平衡摆架静偶分离特性的基础上,为从结构上实现静偶振动的完全分离,提出了一种新型静偶分离摆架结构,采用十字簧杆消除力偶对平动簧板的影响,通过建立系统振动力学方程,讨论了平动和偶动的振动特性,分析了影响静偶分离的各种物理因素。实验结果表明,这种静偶分离摆架结构的偶动对平动的影响甚微,实现了静偶运动有效的分离,消除偶不平衡量对静不平衡量的影响,远远优于传统摆架结构。The static and couple separation swing frame is a crucial technology of double-plane vertical dynamic balancing machine.In order to effectively separate the static and couple vibration in structure,a new swing frame was introduced based on the analysis of the static and couple separation property of traditional vertical dynamic balancing swing frame.It can eliminate the impact of couple on the horizontal movement of spring board by adopting cross spring pole.Through the establishment of vibration equation,the vibration property of statics and couples movement were discussed,and the influence factors of static and couple separation were analyzed.The experimental results showed that the impact of couple on horizontal movement of this swing frame is litter.It can achieve effectively separation of static and couple movement,and eliminate the impact of couple unbalance on static unbalance.
