Numerical approach for airframe assembly simulation

Abstract

Purpose: The paper describes the methodology of contact problem solving that is used for simulation of aircraft assembly process, Methods: The dimension of the problem is reduced after eliminating the unknowns outside the contact zone and the initial problem transforms into the problem of quadratic programming with linear constraints, Results: The special computer code ASRP (Assembly Simulation of Riveting Process) was developed on the base of presented methodology. Now this code is utilized by Airbus. Some results of application of developed code are given in this paper.
