In this study, we present numerical results of texture shape optimization analysis for minimization of the friction coefficient. The Reynolds equation is introduced as the governing equation and discretized in space by the finite element method. The performance function is defined by the friction force. The objective of this study is to find the distribution of the oil film thickness in the textured part i.e., the design variables, in order to minimize the performance function. Here, the adjoint variable method is introduced to replace the constrained optimization problem with an unconstrained optimization problem, and the Lagrange function is derived. The traction method is introduced to obtain the soothed gradient distribution, and the shape update is carried out by using the smoothed gradient. In this study, shape optimization analysis of oil film thickness was performed for a herringbone texture model. Numerical experiments were also conducted for different sliding speeds. In addition, the results are compared with the results of shape optimization of oil film thickness for circular texture by Sasaoka et al2).
