The LOCOMACHS project aims to develop and demonstrate the feasibility of new part production manufacturing and assembly operations of composite and hybrid aero-structures parts. To achieve the ambitious LOCOMACHS objectives, it is necessary to gather expertise in a wide range of skills, and, in order to reach the highest possible impact, the main stakeholders in the field.
The LOCOMACHS Consortium has been drawn up in this spirit and gathers 30 partners covering the full range of the value chain, from early design and development (process, method, software and hardware tools providers), to skills and facilities needed for manufacturing and assembly. Such a coherent set of competencies would be very difficult to find at national level with the same level of expertise in all fields.
The consortium include:
SAMTECH s.a. that is now part of LMS International (under the commercial name “LMS Samtech”), was founded in 1986 from the Aerospace Laboratory of University of Liège. LMS SAMTECH is the European Engineering Software company developing and marketing the general purpose Finite Element Analysis (FEA) code SAMCEF, the Open Object Oriented Multi-Disciplinary Optimization (MDO) platform BOSS Quattro and the Model-Based Engineering Framework CAESAM. The company has a strong background in the linear and non-linear mechanical/thermal analysis of structures, composite or metallic materials, fracture mechanics and damage tolerance, mechanism simulation, parameterised analyses, statistical analyses, optimisation techniques, correlation and model updating. Major European references using LMS SAMTECH tools in the field of aeronautics are mainly AIRBUS, EADS Innovation Works, SNECMA SAFRAN Group, EUROCOPTER, ALENIA Aeronautica, AVIO, MTU, SONACA, SABCA, TECHSPACEAERO etc.
In the context of LOCOMACHS, LMS SAMTECH will work on tolerance management of flexible composite assemblies through the development of Computer Aided Tolerancing software (task 12.2.) and virtual demonstration of design & geometrical variation (task 43.1.), in close collaboration with SONACA, AIRBUS, ENS Cachan and EADS IW. The goal of the new developed software tool will be to model geometrical variations of manufacturing parts, and variation propagation during assembly operations, accounting in particular for redundancies (over-constrained problems). The final objective will be to demonstrate the benefits of the new Tolerancing approach and how it impacts assembly process design.
