Detailed Design

Table of Contents

During the Detailed Design phase, we took our ideas and customer input from the Systems Design portion of MSD, and expanded it. We started analyzing every subsystem to work in concert with each other. We created drawings and schematics, analyzed the system interfaces, simulated the forces and moments in our system to aid in designing a robust system. A running Bill of Materials is tabulated, to document which parts we have decided to use. A Test Plan and the Risk Assessment were also brainstormed so that we can consider how to best engineer our solution.

Prototyping, Engineering Analysis, Simulation

A Matlab m-file was created to analyze the forces and moments on the seat bracket. The inputs of the forces and their geometric locations on the seat bracket are used to determine the forces acting on the bar. We used this method iteratively to help determine what values for our inputs are appropriate and safe.

The m-file can be accessed here and ran through Matlab with the proper inputs: Calculation m-file

The design was placed in Ansys to determine if the device would yield and to determine total deformation due to expected loading:Ansys results

Bill of Material (BOM)

The Bill of Materials is a compilation of all of the components needed in our design. When we were looking at a component, we identified the function it needed to perform, researched different components, and chose the best one based on many factors (task it needs to perform, cost, lead time, etc.).

BOM + Budget

System Interfaces

As the Bill of Materials unfolded, it was important to consider how each component interacts with other parts. It is necessary to do this to make sure that all components are secured in a safe manner.

System Interfaces

Test Plans

The MSD II Test Plan documents our objectives when we enter the testing stage. We have documented our metrics and how to test for the metric. We also document how to measure our results, whether or not it is a destructive test, and where the test resource can be located.

Risk Assessment

The Risk Assessment document identifies the risk involved in our task. The technical risks relating to the design are focused on, and preventative actions to consider during the design phase are identified. A "Plan B" is also identified, if we have a problem during the Building & Testing Phases.

Detailed Design Review

This Review is the presentation when we will present our design to our customers.
