| Abstract: | Engine cylinder block made of functionally structure is of great importance in making automobile light and raising the technology. The functionally block is one of the developmental ways in future. Numerical analysis and delamination research of engine block made of functionally structure is worked out by means of half-analytics generalized Flourier series. Stress response of the engine block is gained at some primary points by dynamic real time test under complex load. Meanwhile result of calculation is verified by the test. This research proves that engine block made by functionally structure is feasible, and also establishs foundation for constructional design of engine block made of functionally structure. |
