摘　　要：针对脉冲激光与阻尼橡胶材料的相互作用,通过设计单脉冲损伤实验测出了脉宽为10ns时的损伤阈值。根据损伤阈值的倍数,改变激光的能量密度进行钻孔加工实验,发现能量密度为损伤阈值的5-6倍,对阻尼橡胶材料加工的效果较为理想。结合损伤阈值的计算方法,在不同的脉宽条件下,可以借鉴本文方法选取适当的加工激光能量密度。In order to research the interaction of pulsed laser with damping rubber material,the damage threshold was obtained by designing a single pulse damage threshold experiment which revealed that the pulse width is 10 ns.An experiment of drilling holes on rubber was carried out according to different energy density of laser.It found that 5to 6times of the damage threshold is the relative ideal energy density for laser drilling on rubber.This paper provides a reference on choosing energy density in the condition of laser processing on rubber by different pulse width.
