Recently vehicle development timeline is becoming shorter, so there is an urgent need to be able to develop vehicles with limited resources. This means the efficiency of the body structure development process must be improved. Specifically it is important to reduce the amount of design re-work required to meet performance targets as this can have a large influence on the body development time.In order to reduce the afore mentioned design re-work, we developed simple calculation models to apply a “V-Flow Development Process” to the preliminary stage design of the automobile body structure.The “V-Flow” advantages are as follows: (1) simple and easy to use, (2) defects are found at early stage, (3) avoids the downward flow of the defects.The advantage of preliminary stage design is that there is design flexibility since not many specifications have been determined yet.The advantage of simple calculation models is their lightness as to input data and calculation time which makes them easy to implement for preliminary stage analysis. It is easy to analyze many changes quickly using these types of simple models.This paper proposes a V-flow development workflow suitable for development of a body at the preliminary stage and the required methods used at each phase of the workflow.
