在2019年召开的 2019 World Congress on Mechanical and Mechatronics Engineering (WCMME 2019) 于4月15-16日在迪拜（Dubai）召开，王骥教授在这次会议做大会报告，介绍了近期研究的基于能量分布的弹性板振动模态识别技术，可以在板的分析中不用画出模态图来识别常见的振动模式如弯曲和厚度剪切、拉伸等，为结构分析和振动利用提供了基于应变能和动能分布比例的模态确定方法。和传统的绘制模态图的方法相比，振动能量的计算相对容易，尤其适用于提供了位移数值结果的限元方法。王骥教授的报告引起了一些进行结构振动研究的与会学者的关注，期望得到在这方面开展研究工作的交流和指导。
王骥教授的研究工作以石英晶体谐振器的分析与设计理论为核心，主要内容包括弹性波理论、弹性板振动分析、结构复杂因素效应、石英材料加工、传感器、振荡电路、射频电路与器件等方向，交流的学术领域包括固体力学、结构振动、弹性波、材料科学以及机械工程等。近年来，王骥教授每年都应邀在一些国际会议做主旨报告(keynote talk)和大会报告(plenary talk)，强化了国际交流，推广了压电实验室的研究成果。
Professor Ji Wang delivered a plenary talk at the 2019 World Congress on Mechanical and Mechatronics Engineering (WCMME 2019), Dubai, April 15-16. In this year’s WCMME, Professor Wang presented his recent research on the energy-based method for the characterization of vibration modes of a quartz crystal plate in a resonator. This research is based on the innovative idea that vibration energy in terms of strain or kinetic energy is concentrated to a specific vibration mode at the given frequency. As a result, we can check the energy distribution at the frequency to label the vibration mode with the largest energy proportion. The technique is especially useful in the finite element analysis because we can use the numerical solutions of displacement for the energy calculation without going through the time consuming drawing and examination process we use frequently. Apparently the talk has been well received in the conference and requests for further explanation of the method have been received from participants.
The research of Professor Ji Wang is focused on the theory of analysis and design of quartz crystal resonators which is closely related to wave propagation, vibrations of plates, piezoelectricity, sensors, oscillating circuits, and RF circuits and devices. In relation to his research, Professor Ji Wang has been invited to international conferences in the fields of Solid Mechanics, Computational Mechanics, Plates and Shells, Ultrasonics, Acoustics, Vibrations, Wave Propagation, Materials Science, and Sensors. The fast dissemination of the research results from the Piezoelectric Device Laboratory has been well enhanced and improved through the visible presence of Professor Wang in major conferences worldwide as keynote, plenary, and invited speakers.
