| 摘要:针对国产化TBD234V12柴油机泵传动机构螺栓断裂故障，对相关零部件进行拆检分析。在排除螺栓和喷油泵传动机构本身问题的基础上，开展喷油泵传动机构振动仿真分析、螺栓强度校核及喷油泵传动机构可靠性分析,发现故障系由在柴油机国产化过程中设计人员未选择与喷油泵配套的专用喷油泵传动机构导致。 |

| Abstract:Aiming at the bolt fracture fault of pump transmission mechanism of localized TBD234V12 diesel engine, the relevant parts were disassembled and inspected. On the basis of eliminating the pro-blems of bolts and fuel injection pump transmission mechanism, the vibration simulation analysis, bolt strength check and reliability analysis of fuel injection pump transmission mechanism were carried out. It is showed that the fault was caused by the designer′s mistake of not selecting the special fuel injection pump transmission mechanism matched with the fuel injection pump during the localization of diesel engine. |
