Abstract: In the era of globalisation, cost competitiveness has been paid more and more attention. In different mechanical products, the material is one of the key factors of cost. The optimisation design using material substitution is one of the important methods to enhance cost competitiveness. First of all, the designers chose the appropriate material according to the material characteristics. Then, they optimised the structure and evaluated its mechanical reliability. The material substitution was divided into semi-design and re-design. The experiments were implemented on the motor pulley and the brake system of the washing machine. The results demonstrate the effectiveness of our research methods.

Keywords: cost competitiveness; structure; mechanical reliability; material characteristics.
