Development of Modeling System for Data Proto Model

Article of Honda R&D Technical Review Vol.16 No.1


Honda’s Data Proto Model (DPM) is a digitally-modeled prototype vehicle generated through the formulation of three-dimensional data for a complete vehicle and the input of the collected data into a computer. This paper discusses the development of two three-dimensional modeling systems for the vehicle body, which forms part of the DPM. One of these systems makes use of global time differences to enable modeling before the issue of design drawings, making an image of the latest body constantly available to designers. The other is a modeling system based on the BOM (Bill of material) established after the issue of design drawings. These systems enable other designers and members of the manufacturing division to refer on a daily basis to the latest form of the body. The DPM also enables constant review of specifications in the initial stages of design. A system was developed to facilitate DPM verification meetings; these bring together specialists to run checks on interference between components, review the design layout, etc., using DPM. As a result, any designer is able to use DPM for verification of the appropriateness of design, and the system is now in use in Honda’s design departments.
