Automotive Engineering - September 2020

Overview

This issue of the Automotive Engineering magazine highlights significant advancements and innovations in the automotive industry, focusing on lightweight materials, electric vehicles (EVs), and cutting-edge technologies that are shaping the future of mobility.

Key Innovations in Lightweighting: The magazine features a spotlight on lightweighting technologies, which are crucial for improving vehicle efficiency and performance. Notably, Marelli's Ride Dynamics team has developed a new steering knuckle made from chopped carbon fiber using an Advanced Sheet Molding Compression (ASMC) process. This innovative composite part offers a 25% mass reduction compared to aluminum and a 50% reduction compared to cast iron, while maintaining strength and resistance to cracking. This advancement allows for the production of complex structural parts in a single, efficient process, suitable for automotive manufacturing.

Additionally, Nissan engineers have created an aluminum/short carbon fiber reinforced thermal plastic bodyside panel that could potentially reduce weight by about 50% compared to traditional steel panels. These developments underscore the industry's commitment to lightweighting as a means to enhance fuel efficiency and reduce emissions.

Recognition of Innovations: The issue also covers the Altair Enlighten Awards, which recognize outstanding achievements in lightweighting. Harley-Davidson's LiveWire electric motorcycle received the top honor for its full vehicle design, showcasing the integration of lightweight materials in electric mobility. Other notable mentions include DuPont’s BETASEAL X2500 structural adhesive, which enables modular assembly of thermoplastic liftgates, achieving a 20-30% weight reduction compared to welded steel designs.

Advancements in Electric Vehicles: The editorial discusses the growing trend of electric vehicle launches, emphasizing the need for improved public charging infrastructure. As the market for EVs expands, the magazine highlights the challenges associated with widespread adoption, particularly the current state of public recharging, which is described as chaotic and inconsistent. The editorial stresses the importance of addressing these issues to facilitate the mainstream acceptance of electric propulsion.

Technological Trends: The magazine also features a section on technological trends, including Mazda's computer-aided engineering (CAE) multi-disciplinary design optimization methodology. This approach utilizes simulation-driven design and data analytics to enhance product development, reflecting the industry's shift towards more data-driven and efficient design processes.

Industry Insights: In addition to technological advancements, the magazine provides insights into the automotive industry's strategic shifts. It discusses the importance of collaboration among manufacturers, suppliers, and technology providers to drive innovation and meet evolving consumer demands. The issue emphasizes the role of partnerships in developing sustainable solutions and advancing the industry's transition towards electrification.

Conclusion: Overall, this issue of Automotive Engineering magazine encapsulates the dynamic changes occurring in the automotive sector, driven by the need for sustainability, efficiency, and innovation. The focus on lightweight materials, electric vehicles, and advanced engineering methodologies highlights the industry's commitment to addressing environmental challenges while enhancing vehicle performance. As the automotive landscape continues to evolve, the insights and advancements presented in this issue serve as a testament to the ongoing efforts to shape a cleaner, more efficient future in mobility.
