摘要
计算了强脉冲离子束与钛靶相互作用的能量损失分布.H+与钛靶相互作用过程中的能量损失在钛靶内较深处,而C+在钛靶表面沉积较多的能量.束流含离子种类不同,入射靶材的深度及传给靶材的能量分布不同,对靶材将产生不同的作用效果.用ABAQUS有限元软件,以单元死活表征汽化材料的体加载方式对靶材钛进行不同能量参数的强流脉冲离子束辐照热效应的模拟计算.得到了强流脉冲离子束辐照金属表面的传热数据.通过分析,验证了模拟结果的合理性和凹坑形成的机理.
Energy distributions were calculated when HIPIB interacted with Ti targets. In the process of interacting with Ti target, H^＋ energy loss in its inner. However, C^＋ disposition was much on the surface of Ti target. Different ions have different depths and different disposition and have different affection. Body Heat Flux Mode using Element removed and reactivated method is built to simulate the thermal effect of target Ti irradiated by HIPIB with different energy using the ABAQUS FEM （Finite Element Method） software. The thermal data of the metal surface irradiated by HIPIB is obtained. The experiment has proved the rationality of the simulated result and the mechanism of the craters formed.
