个人简介Personal Profile
冯伟哲,男,2017年12月毕业于大连理工大学航空航天力学与工程专业,2018年1月留校任教,现大连理工大学力学与航空航天学院副教授,主要研究方向为飞行器气动弹性力学、计算固体力学新方法。曾荣获辽宁省优秀毕业生,大连市青年科技之星,XX研究所兼职主任设计师等荣誉。截止到目前,发表论文30余篇其中,SCI检索论文26篇。作为技术负责人参与JKW基础加强项目1项,参与国家研发项目1项。负责JKW创新特区、JKW基础加强领域基金、ZF基础研究项目多项。
² 飞行器气动弹性力学
针对型号研制和预研工作中的气动弹性,气动伺服弹性,气动弹性飞行力学耦合问题开展了大量的仿真分析和试验研究工作。内容包括:定常、非定常气动力快速计算、颤振分析、热颤振分析、气动伺服弹性、弹性飞行载荷、螺旋颤振、飞行力学/气动弹性耦合建模和联合仿真、地面颤振试验系统等。
² 计算力学新方法
1. 提出了基于耦合边界元(BEM)&面元法(PM)的高速飞行器气动烧蚀数值模拟。
采用线性位势流理论的面元法结合粘性边界层方程对飞行器气动热环境进行快速计算,将气动热计算结果提取出来作为热载荷对飞行器结构进行瞬态烧蚀导热耦合分析。其中,结构导热采用边界元法结合烧蚀移动边界模型对其进行瞬态传热计算。边界元法和面元法都只需要在结构表面离散,两者之间几何相互匹配。相比传统CFD+有限元的方法,BEM+PM方法耦合数据传递更加方便,模型网格重构更加简单,求解效率更高。
2. 提出了对偶界面积分边界元法求解多重介质材料传热和断裂力学问题
边界元法有降低问题维数、计算精度高、只在边界离散、适应于无限域和半无限域问题的优点,目前已经在计算固体力学和传热学领域有了广泛的应用,但在处理非线性、非均质和多重介质问题中仍有很大的局限。针对多重介质问题,提出界面积分边界元法,该方法在数学格式上弥补了传统边界元法在处理多重介质问题的不足,成功应用单一积分方程解决了复合变系数多重介质力、热问题。基于界面积分的思想,首次提出了不含初应力和初应变的新型弹塑性力学边界元求解新格式,革新了已使用40年之久的传统求解格式。针对高阶奇异积分问题,提出多种奇异积分正则化方法,和国际上通用的意大利学者Guiggiani 提出的正则化方法相比,奇异积分计算结果更加精确稳定,处理的奇异阶次更高,程序通用性更强。提出了对偶界面-边界积分方程,能够针对任意多种介质裂纹问题进行弹性界面断裂分析。
² 自主可控CAE软件开发
在求解器方面,参与开发国产自主气动弹性分析软件Defair,自主完成颤振、螺旋颤振、弹性飞行载荷模块开发。基于三维几何造型引擎ACIS和三维显示引擎HOOPS,采用C++面向对象编程开发了CAE软件前处理平台。可以对不同格式B-rep表示的几何模型进行三维显示、交互操作和布尔运算。结合网格剖分程序MeshG,可以对几何模型进行网格剖分。
