Modularity in Chassis Design An investigation of modular product architecture for a chassis of an autonomous electric truck

Abstract

This master’s thesis explores the strategy of modularity in chassis design for au tonomous electric trucks (AET). The study aims to investigate the benefits and challenges of incorporating modular design principles in the development of chas sis systems. The research methodology includes a comprehensive literature review, investigating stakeholder needs impact on a modular chassis design, and using de sign structure matrices to evaluate the performance and the product architecture of modular chassis concepts. The results demonstrate that technology changes are one of the most important factors to consider when developing a modular chassis for an AET. In addition, the research emphasizes the importance of information and energy connections in product architecture as the shift toward electrical and au tonomous technology increases. In contrast to traditional manually operated trucks with internal combustion engines, the focus has traditionally been on spatial (phys ical) connections. A design proposal for the product architecture is also presented based on the evalu ated concepts generated by defining modules with a Design structure matrix. After that, visualized with an overview image with the components divided into modules and interfaces highlighted. Furthermore, the study examines the potential trade offs between modularity and value dimensions identified through a value creation strategy. The findings contribute to the body of knowledge in the field of AET by highlighting the implications of modularity and how it should be applied to the design of a chassis. Estimating future legal and technology requirements and adapt ing to future changes is essential. This research provides valuable insights for AET manufacturers and designers seeking to leverage modular approaches in their chassis development strategies.
