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.
