摘　　要：针对已有摆架在滚子动不平衡量提取过程中表现出振幅不明显、微小不平衡量敏感性差、振动方向不稳定等问题,以模态平衡法为基础分析研究了摆架振动模型,从理论角度提出了改进摆架的思路,设计了一种振幅更明显、灵敏度更高、振动更加稳定的新型滚子动平衡测量机用摆架。试验表明,新摆架设计方案合理,能够明显增加微小转子动不平衡量提取的有效性与稳定性。Aiming at the problems such as unobvious vibration amplitude,poor sensitivity of tiny unbalance amount,instable vibration direction of swing frame during the extraction process for dynamic unbalance amount of rollers,the vibration model for swing frame is analyzed and studied based on modal balance method. The idea for improved swing frame is put forward from the perspective of theory,and the new swing frame is designed with obvious vibration amplitude,high sensitivity and stable vibration. The experiments verify the rationality of design proposal for new swing frame,and the validity and stability of unbalance amount extraction of tiny rotor are markedly increased.
