156A Week 10

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• Preliminary design concepts WIP.

• Analysis, fabrication, and tests pending.

Accomplishments from Previous Week

• Produced 1 CAD/SolidWorks model for review. (Sam & Øyvind)

• Created 3 design concepts for deliberation. (Nicholas & Sean)

• Narrowed down material considerations to 2 configurations. (Ved & Angelica)

• Met with sponsors and professionals supporting the team project, received input on design considerations and resources. (Sam, Ved, Nicholas, Sean, Angelica, & Øyvind)

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• 3 concrete design concepts (Nicholas & Sean)

• 1 scale model of "best" concept (Ved & Angelica)

• FEA/FEM of previous iterations as well as "best" concept (Sam & Øyvind)

• Selected material for trike design (Sam, Ved, Nicholas, Sean, Angelica, & Øyvind)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• Use greater circular diameter for base of frame. (3 in. rods)

• Use Bill Holland as welding resource for titanium.

• Before analyzing, involve professionals/people in industry for reference and input.

• Analyze components. If FEM says a part has a lot of stress, prototype that part for testing.

• Do not constrain yourself to the design of the first two iterations.

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• Develop 3 - 4 design concepts

• Produce 1 scaled model

• Gain knowledge of project background and areas of expertise (history of riders, knowledge of bikes, etc.)

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• N/A

Risks and Areas of Concern

• Material consideration (stiffness, weight)

• Test frame for ultimate and fatigue failure

• Learn from previous iterations (make sure cross member and pedal boom for pilot don't fail)

• Welding/Bending materials

• Capabilities of Lab

Resources or Information Required but not Available

• N/A

Schedule

• Final design consideration including material choice.

• Update Gantt chart.

Budget (list amount spent and amount remaining)
