Assembly Design Defects Identification for Mechanical Products Based on Constraint Verification Tree

Abstract

A methodology for mechanical products assembly design defect identification was presented based on assembly constraint verification tree (ACVT). An identification system framework, which consists of verification tree constructors, modifier, monitor and identification analyzer, was proposed. Modified design parameters were stored into modifier, monitor was employed to supervise design parameters variation in modifier and renew design parameters information in verification tree, identification analyzer decided the start or stop of verification according to stack information in monitor. A prototype system based on above identification system framework was developed, assembly design defects identification results for driving leg of parallel manipulators demonstrate that not only can it enhance identification efficiency for assembly design defects effectively, but also can implement dynamic relating identification for assembly design defects of mechanical products.
