This paper introduced the mechanism of vibration in the process of deep hole boring ,developed a dynamic modal of the damping boring bar,optimizing the parameters of the damping system,analyzed the transient dynamic and harmonic response of the damping boring bar.

介绍了深孔镗削加工过程中产生振颤的机理，建立了减振镗杆的动力学模型，在此基础上优化减振系统的参数，并且对减振镗杆进行瞬态动力学和谐响应分析，分析结果表明该减振系统具有良好的减振性能。

The boring bar was designed into a new structure consisting of two coaxial bars. As a result, the micro-boring bar can be made with relatively smaller outer diameter, which was suitable for boring smaller and deeper hole, even the measuring and compensating sensors have been incorporated.

但是，在镗削加工中就遇到了较大困难，因为镗杆的径向尺寸受到被镗孔尺寸的严格限制，用于误差在线检测的传感器和用于误差在线补偿驱动的传感器不能直接安装在镗杆内。

Since the polymer bar material has a lower mechanical impedance than the concrete specimen, spalling can be produced in the concrete rod after the compressive wave in the concrete specimen is reflected back as a tension wave at the concrete/buffer bar interface.

由于波在粘弹性材料中的弥散效应，吸收杆中透射波形会发生变化，但三维有限元分析表明，在利用吸收杆上透射波确定混凝土层裂强度时弥散产生的影响可以忽略。
