nnovative research on gear transmission foundation theory and transmission structure mode is deeply developed closely around key scientific and technological issues of mechanical transmission in equipment manufacturing industry, thereby providing China's equipment manufacturing industries with a number of selective novel transmission models with excellent properties and simple manufacture. 
It has obtained more than 20 National "863" Programs, National Science and Technology Support Programs, National Natural Science Foundation, and provincial-level project funding since 2003; has applied 46 invention patents and authorized 17 inventions patents,? has won 1 second prize of national scientific and technological progress, 1 provincial first prize, and 2 third prizes, and has published more than 230 articles foreign and domestic academic journals, wherein 52 articles were cited in SCI and EI database. Research work is generally in the leading place in the field of mechanical transmission, and achieves the wond advanced level.

Study on Non-linear Vibration Noise of Gear System
Under the consideration of the rigidity incentives, error incentives, meshing impact incentives and so on of drive system non-linear vibration and noise, bifurcation and chaos, and other dynamic features are studied, and gear box structural analysis and power optimization software has been developed and applied in many enterprises.

Novel Reciprocal Screw Rolling Transmission
A universal reciprocal roll screw transmission mechanism for transforming linear movements into??????? rotation movement is proposed, invented and developed, a variety of modular robot joints and spacecraft angle drive units on the basis of reciprocal roll screw pairs are invented and researched, related research achievements were nominated for National Science and Technology Invention First Prize by Ministry of Education in 2005.

Backlash Adjustable Plane Enveloping Ring Surface Worm Transmission and Processing Equipment
Similar grinding new method of Plane Enveloping Ring Surface Worm was invented and digital control four-axis interlocking ring worms were invented capable of simulating center distance with small size and powerful functions. The achievement was identified as "achievement with important originality and practical results, and filled the gap at home and abroad’.

A Number of Key Theories, Technologies and Applications of Vibration Utilization and Control Engineering (the Second Prize of 2008 National Science and Technology Progress Award)
Creative application foundation studies in the aspect of non-linear vibration and wave energy utilization, mechanical system vibration control and so on were specially developed with vibration utilization and control engineering as features and with non-linear dynamics theory as foundation. The specialty of complex mechanical slowing system was studied, two-parameter slowing systems, nonlinear slugging system with two-way gaps, and other new models and approximate solutions were proposed, and the nonlinear characteristics were? researched deeply.
