镗削加工中的冲击式减振器减振性能研究

THE PERFORMANCE RESEARCH OF SHOCK VIBRATION ABSORBER IN BORING PROCESS

通过 试验研究 ，得到了 在不 同切 削 速度 的情 况 下，冲 击 块与 孔壁 之 间的 间隙 δ与 切 削振动幅值 的关系曲 线，研究 说明，冲 击式减振 器在适 当的 δ值 范围 内减 振效 果明 显，但 如 果δ选 择不合适， 则有可能 使振动加 强图６ ，表２ ，参３

The vibration magnitude can be reduced by applying the shock vibration absorber in boring process ,The curves of the amplitude versus gap δ between the shock block and the hole in boring bar was gained by experiments with different cutting speed .The experiments show that the absorptive results is good when applies shock vibration absorber with suitable gap δ in boring process ,while the vibration may be strengthened with unsuitable gap δ.6figs.,2tabs.,3refs.
