Abstract
We developed a knowledge-based engineering system for designing automotive fuel pump module. This system enables fuel pump module to be designed faster with greater reliability. The system has following four main features : (1) database that enables systematic organization of design knowledge, (2) a design process navigator that guides design procedures, (3) a structural evaluation tool that supports the setting of boundary condition for finite element method (FEM) analysis, and (4) fuel gauge character design and suction performance simulator that are connected to a 3 dimensional computer aided design (3 D-CAD) tool. The effectiveness and reliability of the system was confirmed by designing a test fuel pump module. The total design time was decreased by 1 690 minutes less than manual operation, and the system contributed to improvements in design reliability.
