1. In 1987, he established a theoretical system for dynamic analysis of elastic-viscoelastic composite structures, and won one second and third prize for provincial and ministerial level scientific and technological progress;
2 , In 1994, he pioneered the modeling technology of nonlinear dynamic systems using three vibration signals of acceleration, velocity and displacement simultaneously, which is considered to be one of the main modeling technologies of gray nonlinear systems; 3. In 1999, multivariate statistical process control technology was The research applied to system condition monitoring and fault diagnosis has achieved important results, and has obtained EU and North American application technology patents; 4. In 2006, the principle of liquid-solid mixed medium vibration isolator was proposed, obtained a national patent, and put into application; 5. In 2007, the particle Important progress has been made in damping technology application research and national patents have been obtained. Two international patents and three Chinese patents.
