| Abstract:Considering the structural characteristics of 16V250ZJ diesel engine block, certain dynamic stress test points were selected. The stress state of the engine block’s key parts was studied through dynamic stress test, and was compared with similar types of engines.The results show that the stress amplitudes of 16V250ZJ diesel engine block are smaller compared with similar types of engines, and boasts rational structure and moderate stiffness. This research method and the results offer references for further optimization and improvement of engine blocks. |
