Locating Datum Modeling for Minimum Normal Error in Aircraft Digital Assembly System

摘要

This paper analyzes the status of aircraft digital assembly process locating datum modeling methods, study the localization process of the aircraft digital assembly. By analyzing the error evaluation criteria for assembly positioning, proposed a locating datum modeling method for the minimum normal error, and the locating datum model can get the targeting points of aircraft digital assembly process. Finally, through the digital assembly locating datum modeling of one aircraft to verify, and get a better results.
