Abstract
While there have been tremendous technological improvements in meshing technology in current commercial pre-processors, there is a gap in assembling meshed components. Engineers can usually mesh single parts with relative ease but the steps involved in identifying, cleaning up and modeling assembly features such as small tooling holes, washers, contact surfaces, and lugs consume a disproportionate amount of time and the subsequent step of generating connections and assembling meshed parts is both time consuming and is usually approximated to simulate the load transfer between the assembly parts. An innovative approach that focuses on utilizing assembly features in an advanced simulation framework is proposed. The research will demonstrate advanced techniques for assembly modeling early is in the design cycle to mitigate costs associated with costly retrofits and/or program delays.
