This presentation will report our researches on inversely finding the optimal geometric topology of photonic nanostructures,with synthetically considering the performance and manufacturability.This inverse method is developed based on the topology optimization approach,to overcome the bounds of physical intuition-and conventional optimization-based electromagnetic/optical structure design method.In our researches,the optimal geometric configuration of the nanostructure is determined by a robust iterative solution of a variational problem,where the design variable representing the material distribution in a computational domain is evolved to achieve the desired functional performance mathematically described by a cost function.During the iterations,the geometric constraints (e.g.the feature size and geometric dimension) brought by the used fabrication process (e.g.ebeam lithography,two-photon lithography and femtosecond laser processing technology) can be included,to derive a manufacturable layout.

为了探究异型锥顶双层药型罩射流成形特性，采用数值模拟软件AUTODYN进行射流成形研究。通过与两种典型药型罩结构的对比分析，验证了异型锥顶双层药型罩射流在速度、连续性和能量利用率上的优势。数值模拟结果表明，射流成形受药型罩锥角、辅助药型罩相对位置影响显著，锥角越小或相对位置越靠后，射流速度越高。
本文主要研究指定初始坠撞速度下某型复合材料立柱组件坠撞吸能特性。利用引导式台架开展了坠撞试验，设计了专用的剩余能量吸收装置，获得了坠撞过程的载荷-时间历程。对该构型组件进行了坠撞数值仿真分析，数值模拟的载荷结果与试验测试结果较为一致。在此基础上改变支撑立柱的角度，结果显示立柱角度对该构型复材立柱组件的吸能性能影响较小。
