Light Weighting of Two-Wheeler Frame with CAE - Multi Domain Optimization (MDO) 2024-26-0261

Light weighting in the automotive industry without the use of finite element methodologies is now inconceivable. With the development and enhancement of various CAE tools available, CAE-driven optimization has become part of the product development cycle. Using a variety of CAE techniques in a lightweight optimization process can significantly reduce product development lead time with good results. Traditional light weighting can be done through different iterative approaches with different manual inputs from cross-domain teams, which is usually time consuming and leads to repeated analysis. This method describes the case of a multi-domain optimization approach with the reduction of the frame weight of an e-scooter while considering important cross-domain load cases using CAE. For frame optimization, the important load cases such as Durability/Strength (Normal and Abusive), and NVH (Stiffness, Modes and Vibration) - were taken into account. This Multi Domain/Disciplinary Optimization (MDO) approach has resulted in significant weight savings in the final product, also in reducing the product lead time and cost.
