Automobile Design Using the GENESIS Structural Optimization Program

This paper is a technical report that discusses the application of the GENESIS program for structural optimization in automobile design. It outlines the challenges faced by automobile engineers in determining optimal reinforcement locations and material allocation. The report describes the capabilities of the GENESIS program, which integrates optimization with finite element analysis to solve various structural problems. The authors present studies that focus on maximizing frequencies and optimizing weld locations, as well as the use of composite materials. The document details the methodology for topology optimization, including a novel approach for reinforcing car bodies. Specific examples, such as the optimization of a Porsche 928 car body, illustrate the application of the methodology to maximize bending and torsional frequencies under different mass constraints. The findings indicate that effective material distribution can significantly enhance the rigidity and performance of car structures, providing valuable insights for automotive design.
