Abstract: A certain mining vehicle enterprise, in response to the customer's demands for cost reduction, weight reduction, and improvement of fuel economy performance, has decided to attempt to adopt topology optimization technology to conduct lightweight and cost-reducing design for the current batch matching of mining cast front axle housings. Based on benchmarking the initial scheme and performance indicators as well as ensuring the assembly relationship, with the maximum stiffness of the front axle housing as the optimization objective, the structural material path for casting the front axle housing is determined, and the structural scheme design of the front axle is carried out. The newly designed front axle housing scheme, after analysis and verification, iterative optimization, and elimination of local stress concentration, determined the final optimization scheme. The results show that under the premise of stress and deformation being less than the existing scheme, the mass is reduced by 35 kg, and the weight is reduced by 9.6%.
