1. 1.995 ~ 2002 was the main person in charge of completing the national key research projects "experimental articulated high-speed passenger car bogie and its body connection structure" and "articulated high-speed passenger car body".
2. 1999 ~ 2003, we cooperated with China South Locomotive Group and China CNR Group respectively, and participated in the research work of different types of passenger cars, freight cars, K2 and K6, and exported meter-gauge freight cars, among which "P65 express boxcar" was used.
3. From 2003 to 2006, he undertook the frontier research sub-topics related to the national 863 project "Research on Domestic High-speed Maglev Vehicles", such as vibration of car body structure and fatigue life prediction of key components.
4. From 2003 to 2005, Shanghai Information Commission completed the research of the project "Computer Integrated Platform for Virtual Design and Virtual Test of Urban Rail Vehicles", and put forward and preliminarily developed the performance design and simulation platform of VPD urban rail vehicles.
5. "Double-acting elastic roller side bearing" won the national patent for utility model. This patented technology has stood the test of application in K2, K6 and other railway speed-up and heavy-haul freight car bogies, and has been widely popularized.
