Abstract: Aiming at the fracture problem of the lower beam of the gearbox of a wide-body mining truck frame,the finite element analysis method is used to carry out the two-wheel optimization design after the strength check of the original scheme.Under the premise of ensuring the structural strength,the stress is reduced by changing the structure.Designed to provide an effective means of design to avoid cracking.The optimization results show that the optimization scheme significantly reduces the stress of the lower beam of the gearbox compared with the original scheme,and enhances the strength of the lower beam of the gearbox.

Key words: Wide-body mining truck,Gearbox lower-crossmember, Optimized design, Finite element analysis
