Abstract
In the current vehicle design and development program, the Virtual Product Development process (hereafter, VPD process) is the innovation for automotive industry, which improves product quality and shortens time to market. In general, valid CAE applications are the key component of the VPD process as well as physical tests being indispensable to create valid simulation technologies. This presentation explains how physical-test-based CAE leverages the VPD process. In particular, the presentation is based on how physical testing supports the VPD process and why the ESTECH philosophy is that ‘‘The essence of CAE lies in its synergy with Testing;’’ a philosophy that differentiates the company from the competition. To demonstrate these activities, case studies based on automotive dynamic and real time simulation will be presented. In the case studies, vehicle body NVH and brake noise analysis will be used to show the interaction between physical test and computer simulation. Finally, practical application of the VPD process in one of the leading Japanese automotive companies will be shown, where the effectiveness of the front loading in the actual vehicle development program and the actual deployment of VPD process to the Functional Digital Vehicle project in the powertrain design are to be presented.
