Abstract
In this paper, topology optimization of a main roller for Multi-wire saws is conducted for the purpose of reducing mass of the main roller. Modal analysis is carried out to evaluate whether the resonance could have occurred, or not. The pressure from the cutting wires are modelled mathematically. Topology optimization analysis with the pressure model developed is conducted to derive optimal solution of the sectional shape of the roller. As a result, the cross section of the main roller manifests as an arch shape. The mass of the final optimal model is reduced by 14%, while the deflection and natural frequencies of the roller is same as those of the base model.
