Active Control of Coupled Aeroelastic/Structural Acoustic Systems

9501470克拉克这一职业奖强调与减弱封闭声场的声学响应有关的研究和教育活动，例如飞机机身受到湍流边界层激励。建立了平均速度可压缩流场与封闭声场之间单叶和双叶隔板的气动弹性结构声学耦合模型。湍流边界层噪声模型用于产生系统的外源输入，并通过结构声学控制方法控制声响应。风洞试验用于模型验证和替代控制策略评估。教育计划包括开发机电控制系统演示单元，扩大到当地科学博物馆的活动，设计一门关于自适应结构的课程，并将最新的动力学和控制计算机软件包整合到本科机械工程教学中。

9501470 Clark This CAREER award emphasizes research and educational activities related to attenuating acoustic response of enclosed sound fields such as the fuselage of an aircraft subjected to turbulent boundary layer excitations. A coupled model of the aeroelastic, structural acoustic system is developed for single-leaf and double-leaf partitions between compressible flow fields with a mean velocity and an enclosed sound field. Turbulent boundary layer noise models are used to generate the exogenous inputs to the system, and acoustic response is controlled through structural acoustic control methods. Wind tunnel tests are performed for model validation and alternate control strategy evaluation. Educational programs include the development of an electromechanical control system demonstration unit, outreach to a local science museum, design of a course on adaptive structures, and integration of latest computer software packages for dynamics and control in undergraduate mechanical engineering instructions.***
