【Abstract】 The research work of LHR piston and its structure has been presented and the three-dimensional FEM analysis of the piston and test results have been discussed. The calculated results of pistontemperature field and heat rejection show that the LHR piston can greatly reduce heat rejection andachieve design target.更多还原
