主要学术成果:
1. 拓展了对干摩擦界面耗能机理的认知:揭示了正压力各谐波成分对干摩擦阻尼的影响机制,形成了“二倍频”对阻尼效果影响显著的新观点,得到了时变正压力可较常正压力进一步增强干摩擦阻尼的结论。上述成果是对现有基于“常正压力”的干摩擦阻尼器设计理论的扩充。
2. 丰富了压电结构的机电耦合理论:现有机电耦合理论建立在线性框架内,然而工程结构中接触、大变形等非线性环节的存在使得该理论无法指导压电材料应用于非线性结构的动力学分析与设计。提出了满足“相容性”与“普适性”的非线性模态机电耦合系数,建立了基于非线性模态的计算方法,发展了非线性同步开关电路的等效线性化建模方法,形成了以工程为导向的压电材料拓扑优化技术。为非线性压电结构的分析与设计提供了理论基础与分析工具。
3. 发展了先进的干摩擦、压电试验技术:形成了从界面表征到动力学测试的叶片-干摩擦阻尼结构试验能力,形成了从压电行波激振到可控电路阻抗到压电叶盘动力学响应测试的压电智能结构动力学试验能力。
