In this paper, texture shape optimization is performed by changing the velocity and the effect of speed on the final shape of textures is investigated. The purpose of this study is to find optimal shape of textures so as to reduce friction acting on a sliding surface under fluid lubrication. It is known that the magnitude of the friction depends on the shape of the texture on the sliding surface. Therefore, shape optimization analysis was carried out based on the adjoint variable method and the finite element method. Here, the depth of the texture was defined as the design variable. The evaluation of the friction coefficient is performed under the constant load condition. Therefore, the shape optimization analysis is performed under the constant load condition by adjusting the basic oil film thickness in the analysis. In addition, FreeFEM++ was used to calculate the optimal shape.
