摘要
采用了多学科设计优化方法,根据涡流理论建立了倾转旋翼桨叶空气动力学分析模型,利用CATIA,ANSYS和ADAMS等软件分析倾转旋翼桨叶结构动力学特性,采用iSIGHT多学科设计优化软件集成空气动力学和结构动力学分析模型,建立起倾转旋翼桨叶空气动力学/结构动力学多学科设计优化系统,进行多学科设计优化研究.并以倾转旋翼机XV-15的桨叶为算例,进行设计优化,结果表明提出的倾转旋翼桨叶空气动力学/结构动力学多学科设计优化方法是可行和有效的.
With multidisciplinary design optimization method, an aerodynamic model of tilt rotor blade was set up based upon vortex theory. The structural dynamic characters were analyzed by using software such as CATIA, ANSYS and ADAMS. The aerodynamic model and structural dynamic model were integrated via the help of iSIGHT multidisciplinary design optimization software, thus establishing a multidisciplinary design optimization （MDO） system for aerodynamic/structural dynamics of tilt rotor blade. Take XV-15 tilt rotor blade, for example,this approach to multidisciplinary design optimization of aerodynamic/structural dynamics of tilt rotor blade was feasible and efficient.
