摘　　要：降低柴油机功重比对于节能减排至关重要,某型柴油机已通过对柴油机外部零件采用合金替代铸铁方式实现轻量化。为最大限度减轻产品重量,满足客户需求,通过对某型商用柴油机关键零部件进行分析,同时结合铁型覆砂工艺,采用CAE软件对柴油机轴承盖进一步开展结构与铸造协同设计和优化,满足使用性能要求前提下,改善材料性能。轴承盖铸件工艺验证及可靠性试验结果表明,产品结构强度保持与原零件一致,零部件外观得以改善,毛坯重量减少3.25 kg/套,成品减重0.85 kg/套,节能减排和经济效益显著。Reducing the power to weight ratio of diesel engine is very important for energy conservation and emission reduction.A certain type of diesel engine has achieved lightweight by using alloy instead of cast iron for external parts of diesel engine.In order to minimize the product weight and meet the needs of customers,through the analysis of the key parts of a commercial diesel engine,combined with sand-lined metal mold process,CAE software was used to further carry out the collaborative design and optimization of the structure and casting of the diesel engine bearing cover,so as to improve the material performance on the premise of meeting the usability requirements.The technological test and reliability test results of the bearing cover casting showed that the structural strength of the product was consistent with that of the original parts,the appearance of the parts was improved,and the weight of the blank was reduced by 3.25 kg per set,and the weight of the finished product was reduced by 0.85 kg per set.Prominent energy conservation and emission reduction and economic benefits have been achieved.
