9501285 Franzoni This CAREER award deals with research and educational development in the area of structural dynamics and acoustics with a special emphasis on the Asymptotic Modal Analysis (AMA) method. This method is particularly suited for a study of complex dynamic systems in the middle-to-high frequency range with moderate -to- large levels of damping such as in the case of transportation and flight vehicles. The currently available AMA method is extended to AMA - hybrid method, which predicts responses of moderately to highly damped systems. This is a combination of AMA and perturbation methods that yields physical insights into the role of modal coupling and damping and closed form solutions. The educational component includes teaching, mentoring, outreach, and extension activities aimed at pre college students, undergraduates, graduate students, and practicing engineers. Examples include administering a summer program for high school students, supervising undergraduate research projects, mentoring graduate students, and organizing technical meetings with tutorials for the exchange of ideas between the academe and the industry.***

该职业奖致力于结构动力学和声学领域的研究和教育发展，特别强调渐近模态分析（AMA）方法。这种方法特别适合于研究具有中等到较大阻尼水平的中高频范围内的复杂动态系统，例如运输和飞行器。将现有的AMA方法扩展为AMA -混合方法，用于预测中高阻尼系统的响应。这是AMA和摄动方法的结合，产生了对模态耦合和阻尼以及封闭形式解的作用的物理见解。教育部分包括教学、指导、拓展和扩展活动，针对大学预科学生、本科生、研究生和实习工程师。例如，为高中生管理暑期项目，监督本科生研究项目，指导研究生，以及组织技术会议和教程，以便在学术界和工业界之间交流思想
