Development of an Optimal Design Program for Vehicle Side Body Considering the B.I.W. Stiffness and Light Weight 2007-01-2357

In the primary design step, a well established design guide would be useful for vehicle body design engineers, to avoid trial and error for the desired design.
In this paper, an integrated design program B-SOPT is presented. The B-SOPT is composed of vibration analysis, section property analysis, and section optimization. Vibration analysis procedure is necessary to evaluate the target frequency constraints for optimization. B.I.W. vibration analysis model can be generated and joint stiffness can also be generated automatically by explicit formula derived from using RSM (Response surface method) in the B-SOPT. The presented design program provides a systematic design guide for the vehicle side body structure.
For design engineers, graphic user interface environment is developed with the visual C++ program. A B.I.W design example is given to demonstrate the design procedure using the B-SOPT program.
