Abstract

Distributed dynamic load identification plays a crucial role in structural vibration reduction, noise attenuation, optimization design, fatigue analysis, as well as intelligent and adaptive control. Non-rectangular plates are commonly encountered in practical applications. This paper firstly addresses the challenges involved in extending the method for identifying distributed dynamic loads on rectangular plates to non-rectangular plates. Secondly, coordinate transformation approach is introduced to establish a relationship between non-rectangular and rectangular plates, leading to the proposal of a novel method for identifying distributed dynamic loads on non-rectangular plates. Finally, the effectiveness of the proposed method is validated through both simulations and experiments. The results show an amplitude identification error of 8.6% and a phase identification error of 9.3%, confirming the method's reliability.

复杂非矩形板的分布动荷载识别

分布式动载荷识别在结构减振、降噪、优化设计、疲劳分析以及智能自适应控制等方面具有重要作用。在实际应用中经常遇到非矩形板。本文首先讨论了将矩形板上分布动载荷识别方法推广到非矩形板上所面临的挑战。其次，引入坐标变换方法建立非矩形板与矩形板之间的关系，提出了一种识别非矩形板上分布动载荷的新方法。最后，通过仿真和实验验证了该方法的有效性。结果表明，该方法的幅值识别误差为8.6%，相位识别误差为9.3%，验证了该方法的可靠性。

期刊介绍： The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application. JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
