智利DMU动车组用内燃动力包的研制

Development of a diesel powerpack for Chile DMU

根据智利DMU内燃动车组用动力包供货技术要求,研制了内燃动力包,满足了整车对于动力包输出功率、接口尺寸等各项参数要求。进行了动力包的模态计算、框架强度计算、发电机壳体强度计算、隔振计算和扭振计算,均满足设计要求。完成了动力包台架试验、随车线路运行试验,该动力包已批量应用于出口智利的内燃动车组上。

According to the delivery technical requirements of the Chile DMU powerpack,we developed a diesel powerpack which meet the requirements of the output power,interface dimensions and other parameters for the whole vehicle. The simulation calculation shows that the modality, frame strength, generator body strength,vibration isolation and torsional vibration of the powerpack meet the design requirements. After the bench test and testing in service,the powerpacks were applied to the DMUs exported to Chile in batches.
