The aim of this study was to build a model-based design tool that allows multidisciplinary teams to design vehicle performance targets using an easily understandable common index during the conceptual design phase of vehicle ride comfort performance. The newer a system is in the conceptual design stage without a prototype, the more difficult it is to describe its performance and impact on the vehicle. The originality of this study lies in the proposal of an understandable design tool for the social implementation of new technology, referred to as the multidisciplinary optimization (MDO) and “1DCAE” design concept. More specifically, the subject is the conceptual design of a unique electronically controlled damper system. A model-based development tool was developed, and numerical analysis was performed based on the following approach.

The objective of this study is to introduce and assess a computational tool designed to facilitate product development via sensory scores, which serve as a quantifiable representation of human sensory experiences. In the context of designing ride comfort performance, the specialized terminology—either technical or sensory—often served as a barrier to comprehension among the diverse set of specialists constituting the multidisciplinary team. In a previous study by the authors introduced a tool that incorporated a model of sensory performance, utilizing sensory scores as universally comprehensible metrics. However, the tool had yet to be appraised by a genuine cross-functional team. In this study, the tool underwent evaluation through a user-testing process involving twenty-five cross-functional team members engaged in the conceptual design phase at an automotive manufacturing company.
