Objective This paper explores the usage of Altair simulation driven concept process, C123 for developing the chassis frame of the SUV along with Multidisciplinary optimisation tool. C123 process is useful for strategic & systematic usage of optimisation to generate design alternatives, trade-off information, best balanced designs, design sensitivities, to actively support the concept development process on daily basis. Methodology C123 is used for developing initial concept design of the chassis frame of the SUV. C123 process is independent of vehicle architectures, manufacture process (e.g. extrusions, sheet metal) & material selection (e.g. metals, composites, mixed etc.) and platform sharing strategy. C1 process is used for identification of optimum Structural Layout, C2 is for rapid optimum Sizing of idealized Sections, C3 is used for detailed optimum Sizing of Manufacturable Sections. Automatic process is used for handling pre and post processing process very efficiently. Final refinement of the concept design (C3) will be carried out by considering all the possible critical load cases like Durability, stiffness, Modal Frequency & crash/Impact. Author is also explored usage of advanced high-strength steels (AHSS) which combines the high strength required to meet stringent performance requirements with good formability. Advantage • Efficient and automatic process (user interface, scripts) • Adopted abstraction levels to provide in-time design input • Efficient communication between CAD and CAE • Optimization based methods and processes Keywords: Concept design, C123 process, Sizing, Advanced High strength steels (AHSS).
