摘要/Abstract

摘要： 利用ABAQUS软件对激光推进飞行器进行了单、多脉冲结构冲击响应的数值模拟;建立了变形抛物面焦点区域的数值计算方法,计算出结构变形后的焦点区域的变化程度:发现因结构变形引起的聚焦区域的变化不可忽视,是飞行器设计时必须考虑的因素。

关键词: 激光推进;冲击响应+;焦点区域

Abstract: Numerical simulation of shock response of the flight structure for laser propulsion is carried out for single pulse and multi-pulse using the commercial code ABAQUS.The method that solved the focal area of deforming parabolic of revolution was established.The results show that the change of the focal area due to structure deformation can not be ijnored,this should be considered in designing the flight vehicle.

Key words: Laser propulsion;Shock response+;Focal area
