    • Taking your project to the next level ENGINEERING DESIGN CONSULTANTS & FINITE ELEMENT ANALYSIS
    • ENGINEERING SOLUTION PROVIDER We are engineering design consultants, providing services to wide range of clients ranging from civil, automotive to oil & gas industry. We have more than 30 years of combined experience be- tween us in various engineering sectors. We invest in our people and technology to make sure our engineering capability is top notch. Our services are affordable with reasonable charges yet we do not take shortcuts that compromise the integrity of our design, or our attention to detail. At EDSIL, our clients’ complete satisfaction is of paramount importance to all of us. "At EDSIL we aim to establish meaningful relationship with our clients which ensures the delivery of high quality, cost effective engineering solutions every time.” TAKING PRIDE IN WHAT WE DO DRAUGHTING SERVICES We provide engineering design and Computer Aided Design services, using the latest tools avail- able to keep us abreast with the latest technology in the industry. We provide 2D and 3D CAD draughting services that suit your needs at competitive charge. We invest heavily in our design software and facilities including several plotters to print your drawing of up to A0 size paper. “We are committed to serving our clients and providing the highest quality services and innovative solutions.”
    • FINITE ELEMENT ANALYSIS Apart from engineering and Computer Aided Design services, we offer in-house state-of-the-art simulation services for the stress analysis of solids and structures in statics and dynamics. The analysis can be linear (small strain, linear elastic materials) or highly nonlinear. We take your ideas and an understanding of the conditions they will be used in and create a set of virtual ex- periments to show how the design responds to real world situations. We can examine deforma- tion, stress and strain response to loading, in single parts or in assemblies with multi part contact. We can look at mechanical events, motion of parts, kinematics, and impact. The following shows the magnitude of examples of analysis that we performed. Transient Sequential Thermal-Structural Analysis • Metal forming analysis- large displacement, plastic flow, transient analysis. • Highly nonlinear-material and buckling nonlinearity. • Examples shown in the pictures are the analysis of metal forming of sheet and tube by laser scanning. The analysis can be uncoupled into sequential thermal and stress analyses The thermal problem is solved first to obtain the temperature field, which is then used as ther- mal loading for the structural problem. The same mesh is used for both thermal and mechanical calculations. The problem can be represented by only half of the plate modelled with symmetric boundary conditions. The temperature field caused by a moving laser beam is transient in nature. Laser heating is modelled as moving heat flux used to incorporate the laser beam motion. The temperature-dependant material properties are con- sidered including thermal conductivity, specific heat, thermal expansion coefficient, Poisson’s ratio, elastic modulus, yield stress and density. The temperature dis- tribution, deformations, plastic strains and residual stresses were analysed.

    • ENGINEERING DESIGN SERVICES INTL LTD Finite Element Analysis Services Contact Analysis • Linear contact (glued), frictional, fric- tionless, offset etc. • Various type of contacts (ie; rigid to deformable, surface to surface, sur- face to edge etc) • Gasket analysis • Examples shown in the figure are gears meshing used in rack and pin- ion system. Frictional contact were considered between the gears. Cylin- drical boundary condition was used to model gear rotation, with fixed radial and axial direction. Also pivot joint for a construction tying applica- tion. Linear & Non linear Static Analysis • Material non-linearity (bilinear strain- stress behaviour, hardening, etc.) Before After • Elastic to plastic material transfor- mation • Geometric non-linear buckling or material failure • Large displacements or rotations • Non-linear boundary conditions • Example shown in the picture is a drive carriage parts for a 5 tonne capacity lift. The FEA was vital part of the design where it enhances the structural integrity of the compo- nents due to its extreme loading conditions.

    • ENGINEERING DESIGN SERVICES INTL LTD Finite Element Analysis Services Oil & Gas –Offshore bleed ring Problem Verification of the structural integrity of a non-standard bleed ring for oil rig application. The task is to provide mechanical design calculation to confirm the adequacy of the thickness of body, bolt load and gasket operat- ing performance. Analysis should ensure that the bleed ring can withstand the subjected assembly load and vibration during normal operating condition. Analysis Taking asymmetric advantage only half of the adapter is modelled. Bolts pretension on the adapter body is in accordance with the API Recommended Torques for flange. Bolts pretension on the nipoflanges is derived from requirement in B16.5. The analysis has consid- ered two time steps; 1. bolts pretension and 2. applied internal pressure of up to 5000psi. The stresses were compared to those allowed for the material used and assessed against industry standard. Outcome EDSIL analysis showed that the the proposed body thickness is sufficient to withstand the combination of bolts pretension and internal pressure and working within its strength capacity. “Let us do the THINKING for you” EDSIL, Unit 17, Evans Business Centre, Dane Street, Rochdale, Lancashire, OL12 6XB, United Kingdom Tel: +44 (0)1706 343933 Email: Projects@edsil.co.uk Fax: +44 (0)1706 525080 Website: www.edsil.co.uk
    • ENGINEERING DESIGN SERVICES INTL LTD Finite Element Analysis Services Civil structure– Beam analysis Marina Bay Sands - Mobile Cladding Access Plat- forms: We were asked to provide design for cladding access platforms for what is now the worlds most expensive hotel, Marina Bay Sands, Singapore. One of which was a mobile suspended platform for to provide ac- cess to the underside of the Sky Park 200m above ground level. The platforms had to run on two tracks embedded in the structural steelwork and the platform had to be fully clad which meant wind loading would be a major factor in the design. The platform was modelled using beam analysis. Loads combinations including high wind loading were considered according to national standard. The plat- form was made of aluminium profile, and therefore BS8118 was used as a verification method. Also, a bespoke mobile trolley was design for the sus- pended structure. As this is a one of the critical item in the system, the trolley design was also verified by FEA.

    • Manufacturing-shell analysis Problem To verify the structural integrity of a sheet metal board in accordance with BS EN12811-2. The actual boards of 1.5, 2, and 2.5m length were supplied to us for in- house testing and verification. Testing & Analysis EDSIL has conducted a series of in-house testing as required by the code. Comparing with initial hand cal- culations, the boards failed against the initial design concept of a locked seam. Having to reassess the de- sign as behaving with a far more complex geometry has been difficult. We have then conducted a shell fi- nite element analysis and ignoring the locked seam effect. Outcome We have finally been able to analyse the section in a manner that allows the seam to slip. This has drasti- cally reduced the theoretical board capacity to a point below the tested results. With the test results now be- ing moderately above the theoretical design capacity the tests can now be viewed as proving the capacity of the design. This is a requirement for passing these boards as certifiable to BS EN 12811-3 and giving them a partial designation in accordance with BS EN 12810-1 clause 5.
