Development of First Order Analysis for Torsion Beam Suspension (FOA/TB) Corresponding to Modular Design

The First Order Analysis for Torsion Beam Suspension (FOA/TB)/design tool has been developed as a CAE tool for suspension designers. Reflecting the needs of suspension designers, this tool tends to become more detailed and complex. In addition, FOA/TB is also used by torsion beam component designers since it is capable of creating detailed models of the torsion beam itself. However, in the design phase, torsion beam designers cannot obtain all the parameters included in the current FOA/TB model and have to provisionally set unknown parameters. To overcome this problem, this paper introduces a method for abstraction and masking of design parameters based on the concept of modular designing. It also shows how usability was improved using the new concept FOA/TB.
