Liu Xiaohui, male, is from Yantai, Shandong Province. He holds a Doctor of Engineering degree and is an associate professor and master's supervisor 

at Chang 'an University. In 2019, he was selected as a Chang 'an Scholar young academic backbone.

The main research directions are the design and dynamics of construction machinery (such as the crushing mechanism of geotechnical machinery and 

its material damage, the performance and wear characteristics of cutting tools, the gas-solid coupling dynamics of complex characteristic particles, 

mechanical vibration and noise identification, sound source localization, etc.).

I have presided over one National Natural Science Foundation of China general project, one National Natural Science Foundation of China Youth 

Project, one Shaanxi Provincial Key Research and Development Program Project, one China Postdoctoral Science Foundation General Project, one 

Shaanxi Provincial Natural Science Foundation Youth Project, one Jiangsu Provincial Postdoctoral Research Funding Project, and one Central 

University Basic Research Business Expenses High-tech Cultivation Project. One outstanding doctoral program funded by the Basic Research Business 

Expenses of Central Universities.

We plan to recruit 2 to 3 postgraduate students for the class of 2025. When submitting your resume, please attach your undergraduate grades. 

Our research group also requires students with experience in 3D modeling, finite variables, and MATLAB usage.

Director of the Mining Machinery Branch of the China Construction Machinery Society Reviewer of international journals such as Journal of Mechanical Science and Technology and Powder Technology.
