Taking the bridge track installed in orchard rail transportation as the research object, based on the SIMP variable density method topology optimization theory, the main components of the bridge track main beam are topologically optimized and designed. First, ANSYS is used to establish a finite element model of the bridge type track, and combined with the engineering application situation and the connection characteristics of the main beam of the bridge type track, lightweight design is carried out. Second, the static analysis and modal analysis of the lightweight bridge track are carried out, and the stress, deformation, mass and natural frequency of the whole structure of the main beam before and after the lightweight are compared under the actual working conditions. The results show that even with a reduction of 18.25% in the mass of the main beam, the bridge track still meets the actual operating requirements, and the first natural frequency of the lightweight bridge track is 23.614Hz, which is greater than its maximum operating frequency, and resonance phenomenon will not occur.
