2019年4月9日，应动力与能源学院邀请，马德里理工大学的Carlos Martel教授于学院楼225会议室为老师和同学们做了主题为“主动失谐对随机失谐强迫响应灵敏度的影响”的学术报告。王丁喜教授主持了此次活动。学院十多名老师和同学们参加了报告会，现场反响热烈。

Carlos Martel教授首先从失谐这一概念讲起，介绍了失谐对叶轮机气动弹性的影响，即随机失谐会导致强迫响应模态的局部化。进而引出了主动失谐的概念，介绍了主动失谐可以降低随机失谐强迫响应的灵敏度，并展示了相应的算例。

最后Carlos Martel教授回答了老师和同学们的提问，进行了交流。参加本次报告会的同学增长了见识，开拓了眼界。

报告人简介:

Carlos Martel 自2009年起在马德里理工大学担任教授，他在1995年取得了应用数学的博士学位。他的研究活动始于基本流体力学问题（对流、水波、边界层）的非线性动力学领域。在过去的15年中，他与业界密切合作，参与了叶轮机械不同气弹问题的研究，主要涉及转子颤振和强迫响应振动中失谐效应的分析和描述。发表科技成果40余项，参加国际会议35余次。在过去10年中，他参与了30多个研究项目，领导了其中13个。

Carlos Martel is Professor of Aerospace Engineering at Universidad Politécnica de Madrid (Spain) since 2009, where he also completed his PhD in Applied Mathematics in 1995. His research activity started in the field of nonlinear dynamics applied to basic fluid mechanics problems (convection, water waves, boundary layer). In the past 15 years he has been involved in the study of different aeroelastic problems in turbomachinery in close collaboration with the industry, mostly related to the analysis and description of mistuning effects in the flutter and forced response vibration of rotors. He has published more than 40 scientific and technical contributions, and has participated in more than 35 international conferences. He has taken part in more than 30 research projects, leading 13 of them in the past 10 years.
