Assignment Task

Assignment – Loaded Bracket Design Optimisation
The following criteria will be used to assess the reports:
1. Introduction to the overall design task.
2. Description of the key features of your design and the rationale for the design choices that have been made. (Specifically, why you altered the variables chosen, and how they affect the improved design compared to the initial values).
3. Completion of the simulation experiments with results summary.
4. Technical drawing of optimized design.
5. Conclusion.
6. The overall quality of the report

Basic Details:
For this INDIVIDUAL assignment, a technical report detailing your solution is required. This should be submitted as a single PDF document and submitted through the Turnitin link on Blackboard. 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 and control (ideally before the final 16 experiments).
• A plot of the von Mises stress results along one edge of the base length for all simulations (See Figure 2).
• A plot of the factor of safety for all simulations.
• A plot of the displacement results along the edge of the length for all simulations.
• Consideration of additional design requirements.
• A comparison of the initial to optimized bracket design shown in Figure 3.

Background:
A bracket manufactured from Alloy Steel is loaded with a total of 4000N through four bolt holes down in the vertical direction, fixing a horizontal beam in a structure. The selected design cannot fail in service, so a design of experiments (DOE) approach is to be adopted to optimize to a final 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. The bracket is to be fixed in place through the six holes through the backplate of the bracket. The force loading imposed on the bracket is in the vertical direction via four bolt holes (Figure 2). For this assignment, a structural analysis of the initial bracket must be done, and if the initial bracket is unsuitable for the requirements, a suitable optimized bracket design is to be generated. The assignment part is a structural component for a small structure, where workers will be situated. There is a possibility that the working temperature could increase on occasion by 40 degrees Celsius from ambient temperatures. This may need consideration during the design process. The final part design choice must evidence, using FEA simulation, meaningful information in terms of being low cost, low weight, and suitable strength. The designer must consider manufacturability and sustainability while using an appropriate safety factor to not be under/over-engineered. To help deliver this, the designer is able to vary any FOUR of the control factors (bracket variables), while keeping the remaining variable dimensions as those shown in Table 1.

N.B – You will need to explain your reasoning for your choice of variable changes. For optimization, the simulation should consider two levels (high and low) for each of the altered control factors.

Design of experiments: The Taguchi design of experiments (DOE) method can be used to plan the simulations (Table 2). The DOE objectives are to acquire data in a controlled way, obtaining information about the behavior of the bracket and also identify significant factors affecting the design when it experiences a force. The sixteen experiments will be used to identify a low cost, low weight, and high strength design by investigating the von Mises stress, displacement, and factors of safety responses.

Task:
As part of your procedure, you will need to undertake the following tasks to the design provided:
• Create a 3D model
• Create a simulation study
• Define loads and constraints
• Mesh the model (using curvature-based mesh)
• Run the model and perform a mesh dependency study to ensure the correct results.
• Perform a design study varying FOUR of the model coefficients with low and high value, and obtain the 16 results.
• Find the Von Mises stresses and resultant deformations.
• Plot and compare the stresses and resultant displacements along the left edge of the base lengths of the bracket for each scenario generated, along with the determining factors of safety.
• Is the factor of safety of the model suitable? Under or over-engineered?
