A PARAMETRIC APPROACH TO VEHICLE SEATING BUCK DESIGN

摘要

Vehicle package development is an important part of the entire vehicle design. It consists of determining the occupant's spatial environment, the vehicle's mechanical spatial configuration and the overall exterior/interior dimensions while meeting the engineering requirements, including packaging, structure, manufacturing, etc. Developing and verifying the occupant compartment configuration is usually conducted by using a seating buck. To build a seating buck, vehicle interior surfaces are generated in CAD using vehicle exterior surfaces, package layouts and master sections. During early program stages, this information is scattered, incomplete and constantly changing, which makes the seating buck creation challenging and the package design decision-making more difficult. A new method has been developed to quickly generate the seating buck surfaces from scattered information. It has shown to significantly reduce the time conventionally required for the seating buck surface modeling. This paper documents the method and process and summarizes the potential of the method and its impact on vehicle package design.
