A large number of carbon emissions are generated in the life cycle of metal forming equipment. The movable components are the critical part of the mechanical system in the equipment, which accounts for the carbon emissions in both of manufacturing and use stages. Reducing carbon emissions of the components in the manufacturing stage by lightweight design may result in a significant increment of emissions in the use stage. To overcome the obstacle, a method of matching the mechanical system of metal forming equipment to reduce life cycle carbon emissions is proposed. The effect of the weight of the components that determine the manufacturing’s emission on the configuration of the drive units that determine the emission in the usage stage, was analyzed and quantified. Then, the drive units were reconfigured and optimized to meet the required output force and velocity with the different weights of the components to find the optimal scheme with the lowest emissions in the life cycle. The method was applied to a 2000-ton hydraulic forming equipment, and results indicate that 14.87% of the weight of the movable components can be reduced with a total carbon emissions reduction of 22.48%. The total carbon emissions were reduced by 35.94% compared to that of the movable components through the topology optimization method. The proposed matching method can assist in the low-carbon design of the mechanical system in metal forming equipment.

金属成形设备的生命周期中会产生大量的碳排放。活动部件是设备机械系统的关键部分，影响着制造和使用阶段的碳排放。通过轻量化设计减少部件在制造阶段的碳排放，可能会导致使用阶段的排放大幅增加。为了克服这一障碍，提出了一种匹配金属成形设备机械系统以减少生命周期碳排放的方法。分析并量化了决定制造排放的部件重量对决定使用阶段排放的驱动单元配置的影响。然后，对驱动单元进行重新配置和优化，以满足不同重量的部件所需的输出力和速度，从而找到生命周期内排放最低的最佳方案。该方法应用于2000吨级液压成型设备，结果表明可减少活动部件重量14.87%，碳排放总量减少22.48%。通过拓扑优化方法，与可移动部件相比，总碳排放量减少了35.94%。所提出的匹配方法可以辅助金属成形设备机械系统的低碳设计。该方法应用于2000吨级液压成型设备，结果表明可减少活动部件重量14.87%，碳排放总量减少22.48%。通过拓扑优化方法，与可移动部件相比，总碳排放量减少了35.94%。所提出的匹配方法可以辅助金属成形设备机械系统的低碳设计。该方法应用于2000吨级液压成型设备，结果表明可减少活动部件重量14.87%，碳排放总量减少22.48%。通过拓扑优化方法，与可移动部件相比，总碳排放量减少了35.94%。所提出的匹配方法可以辅助金属成形设备机械系统的低碳设计。
