156B Week 7

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

• • All efforts on moving forward with modified gimbal design

  • Calculations done regarding movement of cuff relative to ankle and associated spring response

Accomplishments from Previous Week

• • Settled on final design to move forward with

  • Specifically set individual roles through rest of the project

  • In process of finalizing CAD

    • Cuff

    • Base

    • Joint system

  • Purchased materials

    • Taulman 910 alloy - compatible with Stratus

    • Different suspension components (springs, rubber)

    • Wood

    • Aluminum (machine shop)

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

• • Build base that can attach to ski - Jake

  • Finalize CAD for cuff and 3D-print initial prototype - Harry

  • Finalize CAD for modified- gimbal system and fabricate/build initial prototype- Johnny

  • Finalize CAD for suspension system and fabricate/build initial protytpe- Xian

  • The team will work collectively to integrate all components together

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

• • Supportive of decision to move along with gimbal design (met in person to present options available for moving forward)

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

• • Some comments on how to improve on class presentation

  • Wondered if design is over/under-constrained (email)

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

• • Annotate images to better explain ski kinematics

  • Consider using rubber material rather than springs

  • Material concerns

  • Look into steering stabilizers on mountain bikes

  • Concerns with jamming on slider

Risks and Areas of Concern

• • Exact positioning and strength of components providing resistance

  • Time is a serious factor

  • Slider Alignment and jamming

Resources or Information Required but not Available

Schedule

• • Describe upcoming milestone

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • $1100 remaining

Progress on Report and Webpage

• • Updated continuously
