The laboratory

LIMA (Laboratorio di Ingegneria Meccanica ed Aerospaziale) operates in the field of consultancy and services for industrial engineering.

It carries out theoretical and applied research and contract work for external parties.

It encompasses various skills ranging from industrial technology applied to the automotive, aeronautical and naval fields to the analysis of materials used in these fields and integrated design.

The approaches used are both numerical-computational and experimental and involve different study methodologies such as:

  • For the numerical analysis aspect: CAD solid modelling, FEM and CFD simulation,
  • For the experimental analysis aspect: the complete characterisation of the elastoplastic behaviour of conventional and composite materials.

Since 2012, the laboratory has been providing scientific consultancy services under contract or on behalf of third parties for various public and private entities operating in the field of industrial engineering.

The main subjects for which LIMA has carried out activities include:
SELEX GALILEO, LEONARDO FINMECCANICA, POLITECNICO DI MILANO, FLYING LEGENDS, TRENCH.

The LIMA laboratory also offers pre-degree training for students of the Faculty of Engineering and Architecture, particularly those in their third year of Aerospace Engineering.

During the training period, students can follow and participate in the activities carried out in the laboratory, working alongside the structured staff.
Students may also carry out experimental and numerical research to write their final dissertation.

Regulations and decrees

The LIMA laboratory was established by Decree No. 21 of 23 May 2012 by the Dean of the Faculty of Engineering and Architecture.

As of 1 January 2017, as part of the reorganisation of the Research Centres and Laboratories of the Faculty of Engineering and Architecture, the LIMA laboratory has been assigned to the MARTA Research Centre (Mediterranean Aeronautics Research & Training Academy), as per Decree no. 174 of 30 December 2016 of the President of the University of Enna Kore.

Organisation

Since its establishment in May 2012, the LIMA laboratory has been under Prof. Davide Tumino, associate professor in the scientific-disciplinary sector ING-IND/15 Design and Methods of Industrial Engineering.

In addition to being the head of the laboratory, all the lecturers in the core subjects of the Aerospace Engineering degree course also report to the laboratory.

Research

The laboratory supports interdisciplinary research topics ranging from the analysis of the mechanical behaviour of materials of practical mechanical and aeronautical interest, such as composite materials and intelligent materials, to problems connected with wind engineering (study of wind turbines with structural and aerodynamic optimisation), the study of joints between metallic and/or composite materials, and problems connected with new additive manufacturing technologies.

Below is a list of the main research activities supported by the LIMA laboratory within conventions (or third parties) and funded research projects.

  • Numerical simulation of the thermo-mechanical behaviour of avionics components: using Finite Element codes, simulations were carried out on various types of avionics components to determine their mechanical stress state due to operation and assembly joining processes.
    The analyses, carried out under non-linearity, allowed the verification and optimisation of the most stressed parts.
    Applicant party: SELEX GALILEO.
  • Thermal and mechanical shock simulation of electronic components: Using Finite Element codes, simulations were carried out on different electronic components to determine their thermal state and mechanical stress due to operation and mechanical stress scenarios from PSD and acceleration ramps.
    The analyses, carried out under non-linearity, allowed the verification and optimisation of the most stressed parts.
    Applicant party: LEONARDO FINMECCANICA.
  • Mechanical characterisation of the tensile behaviour of bonded metal joints: Employing tensile tests on the material testing machine, the effect of adhesive and geometry on the strength capacity of a simple overlap joint was investigated.
    Applicant party: POLITECNICO DI MILANO.
  • Verification of the mechanical stress state on a capacitive transformer: numerical finite element simulations of static and seismic tests were carried out on a capacitive transformer installed on a supporting truss.
    Analyses enabled the most stressed parts to be checked and optimised.
    Applicant party: TRENCH ITALY.

SIADD “Innovative solutions for quality and sustainability of ADDitive manufacturing processes” PON “Research and Innovation” 2014-2020, funded by the Ministry of Education, University and Research. Scope of Specialisation: Intelligent Factory.

Within the framework of this project, numerical simulation activities were carried out in the LIMA laboratory for the mechanical study of latex cells moulded by metal powder casting and of plastic composite materials reinforced with curvilinear fibres.
In addition, the research activity also included a campaign of experimental tests on the materials testing machine to determine the mechanical properties of both metallic and composite materials.
