Prof. Li Cheng, Chair Professor of Mechanical Engineering of ME Department was awarded the 2019 Second Prize of the Science and Technology Progress Award by the People’s Government of Guangdong Province, China.

The prestigious prize is the fruit of long-term collaboration that Prof. Cheng and his team have been undertaking with Midea Ltd, the largest domestic product company in China.  During the last two years, Prof. Cheng’s research team has been closely collaborating with Midea through a number of research and consultancy projects, targeting some bottle-necking noise and vibration problems that the company was facing.  The project on which the award was granted concerns the development of a complete set of design, analysis and optimization tools on the use of Micro-Perforated Panels (MPP) for sound absorption and their application in a wide range of key products that Media is manufacturing.

According to the company’s report, the MPP-based technology has been  successfully implemented in a total of 1.6 million Midea’s domestic products, which has up to now secured a net additional income amounting to 1.93 billion RMB.
