| 摘 要： | 对某车型上底盘悬架类零件进行轻量化设计,由铸钢件改用等温淬火球墨铸铁件.通过对原材料、铸造和热处理等工艺过程的严格控制,力学性能稳定达到了ASTM A897/A897M-06 Grade 1050-750-7要求,并实现了小批量生产.从试制及装车路试情况来看,满足了所设计的性能要求,零件重量减少了39.6%,并在后续改进中,进一步增加等温淬火球墨铸铁件数量,整车的等温淬火球墨铸铁件重量达到了550.4 kg.

| Abstract: | Lightweight upper chassis frame suspension part was designed,using austempered ductile iron(ADI)casting instead of steel casting.By strictly controlling the raw material and foundry and heat treatment processes,the mechanical property of the casting satisfies the specifications of ASTM A897/A897M-06 grade 1050-750-7,and the pilot production was realized.The trial production and test result indicate that the properties of casting meet the designed requirement,while the weight of the casting was reduced by 39... |
