Abstract: Aiming at the problem that it is difficult to quantify and reduce the carbon emission in the service process of product parts,a low-carbon demand-driven optimization design method for product parts parameters was proposed.A recursive quantization model of component design parameters and carbon emission was established based on the dynamic interactive evolution characteristics of energy during component service.Morris global screening method was used to characterize the parameter sensitivity and coupling strength of components to screen key low-carbon design parameters.A low-carbon optimization model based on the improved balance optimizer algorithm was established with the goal of minimum carbon emissions during component service.The Metropolis criterion was introduced to construct the probabilistic fitness selection strategy,and the candidate solution selection method was improved to reduce the optimization deviation,so as to obtain the optimal parameter design scheme.Finally,the low carbon design parameters of electric tractor were optimized to verify the feasibility and effectiveness of the proposed method.
