Design of Machine Elements: An Automotive Engineering Perspective

Synopsis

Design of Machine Elements: An Automotive Engineering Perspective is meticulously crafted for sophomore and junior-level engineering students embarking on the critical task of designing automotive structures. This textbook provides a comprehensive exploration of mechanical design principles, tracing its evolution from historical applications to contemporary product development. The course material is structured to build a robust understanding, beginning with fundamental kinematic principles, material science, and the mathematical underpinnings of static and dynamic analysis essential for automotive body structure design. Through practical examples and detailed problem-solving sessions focused on a typical front-end module, students will grasp load paths and industry-standard design methodologies. The curriculum delves into the intricacies of automotive body structures, covering their importance, regulatory requirements (FMVSS, SAE), and the historical progression from Body-on-Frame to Unibody designs, while also looking towards future innovations. Students will gain practical skills in material selection through stress and strain calculations for common automotive materials like steel, aluminum, and plastics. The text emphasizes analytical design, guiding students to assess structural behavior, stiffness, and deflection against regulatory standards. Furthermore, it addresses potential failure modes through FMEA, static and fatigue analysis, and the crucial application of safety factors. Finally, the book concludes with an in-depth look at joining techniques, including welding, bonding, and fasteners, providing the knowledge to effectively assemble automotive components and calculate joint strengths. Each chapter is supported by a 40-slide presentation outline, ensuring a thorough and engaging learning experience.
