| Abstract: | During the development of high-speed and high-power diesel engine,the reliability problem of piston structure was solved through structure optimization design of cooling duct,profile,the clearance of piston-liner, and piston groove of integral casting pistons.The hybrid reinforced aluminum matrix composites was applied.The numerical analysis of thermal-mechanical coupling and experimental verification were carried out.The results of parts test,endurance bed test,road test and vehicle environmental adaption test show that the piston has better structure reliability.In addition,the research direction of reinforce for the aluminum alloyed piston was furthermore put forward. |
| Keywords: | diesel engine piston structure design temperature field coupled analysis durability test |
