Research

National Natural Science Fund of China, (NSFC), Vibration reduction mechanism of hard coating for the thin-walled components of power equipment, 2014.1~2017.12, 800 thousand yuan, Responser

The hard-coating technology is a kind of new and important measure of vibration reduction for the thin-walled components of the power equipments, which are suitable the working condition of power equipments and can suppress the harmful vibration effectively. Due to not understanding of the hard coating damping mechanism, the application of this vibration reduction technology has been restricted severely. In this project, the thin plate and cylindrical shell which can simulate typical thin-walled components of power equipments are chosen as study objects, the damping theory of hard coating and the relative test method will be studied. The study contents include characterizing the nonlinear damping characteristic of hard-coating composite structure, determining the nonlinear constitutive model of hard-coating materials, depicting the nonlinear dynamics mechanism of hard-coating composite structure and analyzing the effect of hard coating on the parameters of vibration characteristic of composite structure, etc. Through this project, the dynamics mechanism of damping vibration reduction used hard coating will be revealed from the point of macro dynamics, the systematic vibration test methodology and the relative analysis method for the hard-coating composite structure will be set up to meet the design needs of vibration reduction. Ultimately, the study of this project will provide the technical support for the application of hard coating damping technology in the thin-walled components of power equipments.

 

National Natural Science Fund of China, (NSFC), Dynamics analysis and optimization of the moving combined interface for the high-grade CNC machine tools, 2010.1~2012.12, 200 thousand yuan, Responser

In high-grade CNC machine tools design process, the vibration analysis theory of joints is necessary to be established to guide design because the characteristic of joints affects the stiffness, damping, machining accuracy and efficiency. The characteristics of joints of spindle and linear guideway systems are studied in this project. On the basis of considering the nonlinear characteristics of spindle and linear-guideway-systems joints, this project established the dynamic models, studied the dynamic and nonlinear characteristics and the experiment methods of spindle and linear guideway systems.
