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 is introduced which is based on the analysis 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 is discussed, the influence factors of static and couple separation is analyzed. The experimental results show that the impact of couple on horizontal movement of the swing frame is litter, it can achieve effectively separation of static and couple movement, and eliminate the impact of couple unbalance on static unbalance, so it is far better than traditional swing frame structure.
