8月28日下午15点30分，澳大利亚伍伦贡大学李志雄博士在腾讯会议室受邀做学术报告，题目为“风机运维关键技术”，四十余位师生云端相聚此次报告。报告会由我院毛磊教授主持。
李志雄博士给与会师生带来了一场精彩的必威最新 。李志雄博士指出伴随风力发电技术的发展而来的是高额的机组运维费用，如何有效运维是一大难题。在事后维护已被淘汰、计划维护过于浪费的当今，智能化的视情维护是解决维护过度或不足的有效手段，包括传感器技术、故障诊断技术、状况预测技术以及维修决策技术四个方面。其中故障诊断与状态预测的结合，以及局部零件退化对风电齿轮传动系统的影响是如今面临的难点和挑战。他在报告中详述了关于视情维护的研究思路，并给出了在故障诊断、状态预测以及局部退化与系统健康状态评估建模几方面的相关研究成果。在自由讨论环节，与会师生积极提问交流，反响热烈。
报告人简介：
Zhixiong Li (SM’19)is currently appointed as aDECRA fellowin University of Wollongong, Australia, focusing on the development ofdata-driven based modelling of engineered systems. He received his PhD in Transportation Engineering from Wuhan University of Technology, China at 2013. Before joining in Wollongong, he engaged in Postdoctoralresearchin University of New South Wales (2015-16),Iowa State University (2017)and University of Central Florida (2018). In the past 10-year continuous research work, he managed three NSFC grants and published more than 80 peer-reviewed papers (most in top-tier journals). He serves as an active referee forEuropean Research Council (ERC), Australia Research Council (ARC), National Science Centre of Poland (NSC), etc. He is currently a Deputy Editor of Ocean Engineering and an Editorial Board member of ASME Transaction - Journal of Nondestructive Evaluation, Diagnostics and Prognostics of Engineering Systems.
