Institute of Mechanics (IMECH), Chinese Academy of Sciences (CAS),  upholds the conception of engineering science by Professor Qian Xuesen (Hsue-Shen Tsien). Its focus areas include key generic technologies and core scientific issues that constrain major national missions. The Institute promotes deep interdisciplinary collaboration among mechanics and relevant fields. Additionally, it establishes a comprehensive innovation chain that extends from fundamental research to technological advancements to system integration.

The main research directions of IMECH include micro-scale mechanics and trans-scale correlation, high-temperature gas dynamics and trans-atmosphere flight, microgravity science and its applications, key mechanical problems in oceanic engineering, environment, energy and transportation, mechanics in advanced manufacturing, biomechanics and bioengineering, etc.

IMECH has five physical laboratories: State Key Laboratory of Nonlinear Mechanics (LNM), State Key Laboratory of High Temperature Gas Dynamics (LHD), National Microgravity Laboratory (NML), Key Laboratory for Mechanics in Fluid Solid Coupling Systems Chinese Academy of Sciences (LMFS), and Wide Range Flight Engineering Science and Applications Center (WESA).

Since its establishment, IMECH has accomplished a large number of important research projects and obtained many remarkable scientific and technological achievements. The Institute has received more than 280 national and regional awards, including one China’s Preeminent Science and Technology Award, four Special Award, three First Prize, 14 Second Prize, 37 National Science and Technology Awards, as well as 35 awards from CAS and the ministries.
