Contact Analysis

Linear & Non linear Static 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.

Material non-linearity (bilinear strain-

stress behaviour, hardening, etc.)

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.

Finite Element Analysis

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.

Marina Bay Sands, Singapore - Mobile Cladding

Access Platforms:

We were asked to provide design for cladding access

platforms for what is now the worlds most expensive

hotel, Marina Bay Sands. One of which was a mobile

suspended platform for to provide access to the under-

side 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 fullyclad 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.

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 calculations, the boards failed

against the initial design concept of a locked seam. Having to reas-

sess the design as behaving with a far more complex geometry has

been difficult. We have then conducted a shell finite 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 drastically reduced the theoretical

board capacity to a point below the tested results. With the test re-

sults now being 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 EN12811-3 and giving them a partial designation in accordance with BS

EN 12810-1 clause 5.
