Multi-material topology optimization for automotive design problems

Abstract: The algorithms for multi-material topology optimization were developed to solve compliance-minimization problems and applied to engineering problems in automotive concepts and lightweight design. Two small-scale problems of a long cantilever and a control arm were studied initially to verify the effectiveness of the developed algorithms and in-house program. Optimal solutions achieved by the multi-material topology optimization method developed were compared to their counterparts obtained by standard single-ma… Show more

“…Li and Kim demonstrated the effectiveness of the three‐phase SIMP formulation with an optimization study of a complex engine cradle. The optimized engine cradle design achieved by their three‐phase SIMP approach was over 23% stiffer than the design achieved by single‐material topology optimization, while maintaining the same mass …”

“…The optimized engine cradle design achieved by their three-phase SIMP approach was over 23% stiffer than the design achieved by single-material topology optimization, while maintaining the same mass. 13 The SIMP formulation can be further extended to m-phase materials, but this is often limited by computational costs since an extension to m-phase materials requires (m − 1) DVs for each element. Alternative approaches that can represent m-phase materials without increasing the number of DVs include a continuous peak interpolation function proposed by Yin and Ananthrasuresh, 14 and a piecewise interpolation curve proposed by Zuo and Saitou.…”

“…As a result of the interaction of the constant magnetic flux with the stator field, a torque is generated. Consequently, the energy, weight, size and dynamic performance of a permanent magnet synchronous machine depends on the properties and topology of the materials used in the manufacture of the rotor [1,2,5].…”
