ABSTRACT: Lightweight frame is very important to engineering machinery. In this
paper, a lightweight design method is proposed for a mechanical mowing truck
frame. This method combines topological optimization with topology optimization
to design the frame successfully. Based on the finite element simulation, the
strength analysis of the two working conditions (bending condition and torsion
condition) for the mowing vehicle frame is carried out on the basis of
satisfying the requirements of the frame work strength. This paper makes a
comparative analysis of the frame after the second optimization using the
combined method proposed. The comparison results show that the optimized frame
meets the strength requirement, and its quality is 34.3% lower than before. The
lightweight effect is obvious.
