摘　　要：文章提出了一种基于空腔等效质量的焊接转子平衡优化方法,解决了焊后修正过程中由空腔引起的偏心问题。通过跳动采集系统获取外轮廓数据并计算各段圆心坐标,考虑左右轴颈端偏移量约束和剩余不平衡量,优化目标函数以最小化不平衡。采用遗传算法求解最优方案,并对比优化前后不平衡量及时域、频域振动数据。结果表明,该方法显著降低了不平衡量,有效减小了振动。A balance optimization method for welded rotors based on cavity equivalent mass is proposed to address the eccentricity caused by cavities during post-welding corrections.Outer contour data is collected and center coordinates for each rotor section are calculated.The objective function is optimized to minimize imbalance,considering the constraints of shaft neck offsets and remaining imbalance.A genetic algorithm is used to find the optimal solution,and comparisons of imbalance and vibration data before and after optimization show significant reduction in imbalance and vibration.
