Sammanfattning
Increasing customer expectation on perceived quality for a premium passenger vehicle
enables the automotive industry to focus on ensuring better fit & finish to
deliver robust build vehicles. The development of verifying geometrical parameters
on a vehicle in a virtual environment would save more time and money than working
on a physical prototype. Finding such a virtual environment which allows to define
and communicate the geometrical parameters is crucial for the automotive industry.
Hence, the thesis was carried out in collaboration with Perceived Quality Geometry
and Appearance group (PQ G&A) at Volvo Cars Group (VCG). This thesis aims to
investigate the feasibility of defining geometric requirements for fit and finish such
as gap and flush in 3D design environments of Computer-Aided Design (CAD) systems
and/or visualization tools available within the Product Lifecycle Management
(PLM) software. Also, the solution obtained should present the defined geometric
requirements in the form of Portable Document Format (PDF document) and improve
the accessibility of information flow between PQ G&A and the requirement
receivers, also referred to stakeholders.
Product development methodology was used to develop the solution for geometric
requirements definition. Interviews were conducted with both PQ G&A and their
stakeholders to understand the current working procedure of defining geometric requirements
using a CAT software and their needs for a new solution. Also, software
development experts were interviewed to understand the current and future development
possibilities of the existing software available within VCG. Based on the
result of the interview, four functional areas were identified and forty-seven product
specifications were listed. Finally, four concepts which can fulfil the needs of PQ
G&A in defining geometric requirements within 3D design modelling environment
were identified and evaluated.
The Catia V5 and 3D PDF add-on software were the proposed solution for defining
geometric requirements. Today, this proposed solution partially fulfils the need of
PQ G&A and require macro programming by the software development team to fulfil
the complete list of the product specification. The proposed solution benefits in
defining the geometric requirements within a 3D design environment and improves
the accessibility of the information to its stakeholders. Yet, the efficiency of the
solution can be evaluated only after completing the macro programming.
