EG-264
Assignment – Industrial Loaded Bracket Design Optimisation
The assessment for this task will be based on an individual’s report (5 PAGES
MAX INCLUDING the Part Drawing (drawing must be A3 in size) - NO
appendices, cover page does not count towards page total. Any pages after
reaching the page limit will not be marked. This assessment contributes 50% to
the final grade of EG-264.
The following criteria will be used to assess the reports:
1. Introduction to the overall design task (10 %).
2. Description of the key variables of your design and the reasoning for the
design choices that have been made (20 %). (Specifically, why you altered
the variables chosen, and how they affect the improved design compared to
the initial values and those not altered).
3. Completion of the simulation experiments with results summary (20 %).
4. Technical drawing of optimised design (10 %). – (N.B If the part cannot be
manufactured from the drawing, the max mark for this section will be 4%).
5. Conclusion (20 %).
6. Overall quality of report (20 %).
Basic Details:
For this INDIVIDUAL assignment, a technical report detailing your solution for the
optimisation of the design is required. This should be submitted as a single PDF
document and submitted through the Turnitin link on Canvas.
In the report you should consider (but are not limited to)
• The analysis of the optimum design for a low cost, low weight and high
strength product, but it is NOT to be over/under Engineered (all claims must
be backed up with evidence).
• Demonstration of mesh refinement (before the final 16 simulations).
• A plot of the von Mises stress results ALONG one edge of the shelf length for
all simulations (See Figure 2).
• A plot of the bracket’s factor of safety for all simulations.
• A plot of the displacement results ALONG the edge of the shelf length for all
simulations (See Figure 2).
• Consideration of additional design requirements - What temperature can
the final optimised bracket design be used in?
• A comparison of the initial to optimised bracket design shown in Figure 3.

Background:
An industrial bracket manufactured from Alloy Steel is used in an industrial
environment used in conjunction with other similar brackets, each fixed to a plate
on a wall. A shelf lays on the horizontal surface and is attached using three vertical
bolt holes (6mm diameter). The mass applied to each individual bracket (acting
vertically down) is 110kg ±10%. The brackets are supporting the shelves in a
working warehouse, in which there is no air conditioning for the workforce, and so
the temperature varies throughout the year. The temperature can reach a high
point of 40 degrees Celsius.
The selected design cannot fail in service, so a design of experiments (DOE)
approach is to be adopted to optimise to a final suitable product. The bracket is to
be made as light as possible and MUST NOT be considered under or over
engineered.
An initial design structure has been generated, and there are several variables that
are used to create the initial bracket design as shown in Figure 3, with numerical
values stated in Table 1.
