摘要

Due to recent technological advancements and a competitive market, most automobile OEMs seek lightweight, efficient, reliable, and cost-effective products. In this direction, the industry employs various weight optimization techniques such as topology optimization. This method enhances structural stiffness and reduces weight by optimizing material distribution. However, this technique lacks control over localized stresses. Typically, topology optimization is followed by a couple of detailed stress analyses to achieve desired levels. This will increase analysis time and fall short of an optimal solution. In contrast, topography optimization redistributes mass while closely controlling localized stresses. The current study explores a combined simulation setup that integrates the benefits of both topology and topography optimization. This paper focuses on a transmission component, where the joint optimization approach reduced localized stress by 40% compared to topology optimization alone. GENESIS along with ANSYS® is utilized for model setup and defining loads, and boundary conditions.
