Abstract

In order to study the influence of locator layout on assembly quality, the side-body outer panel of auto B pillar was chosen as the object. Based on response surface methodology (RSM) and 3DCS, the quadratic response surface models were built up. The multi-objective function was optimized to get the best combination of locating parameters by Design-Expert software, that is, the coordinate values of locator blocks were L1x=1375 mm, L2x=1560 mm, L3z=325 mm, L4z=349 mm. The numerical simulation results by 3DCS show that compared with the assembly results of initial locator layout, the optimization objectives were decreased by 35.2%, 22.9% and 23.6% respectively, meanwhile the superb rate was reduced to a qualified range, effectively solving the problem of excessive gap in the traditional assembly process. The production practice results further prove the feasibility of the methody.
