基于振动方程，采用传递矩阵法和模态叠加法，推导了镗杆的工作变形公式；应用算例对该工作变形公式进行了验证。选取普通镗杆和阻尼镗杆作为研究对象，采用该工作变形公式快速分析两种镗杆的工作振型、模态贡献量和频响曲线，进行对比分析，指导镗杆的结构设计。结果表明该工作变形分析作为快速分析镗杆工作振动特性的新方法，为镗杆结构参数设计计算提供了新的参考依据。

Based on vibration equation, a ODS formula of boring bar was deduced with transfer matrix method and mode super-position method.An example was used to verify the accuracy of this method.A general boring bar and a damping boring bar were selected as objects of study.The ODS, modal contribution and frequency response curve of this two kinds of boring bar were researched rapidly with this method.Comparisons of the results were used to direct structural design of boring bar.The results show that ODS analysis based on this ODS formula is a new method to analyze operational vibration characteristic of boring bar rapidly.It provides a new reference basis for structure parameter design calculation of boring bar.
