156B Week 8

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

• • Design

    • Motor mount is finalized as a cantilever with tension cables, see figure below

• • Fabrication

    • Finishing fabrication of the wood supports

  • Motor and Motor Controller

    • Test for functionality

Accomplishments from Previous Week

• • 6061-T8 2 inch diameter 0.12" wall aluminum tubes ordered

  • Acquired a laptop with LABVIEW

  • Completed most of the self-reacting frame

  • Bottom load frame complete

  • Ordered pulley system, just pulleys

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

• Self-Reacting Frame and Supports (Sergio)

  • • Wood for the end supports

      • Need to cut down to size

      • Bore holes for some bolts to fit

      • Fasten to the rest of the self-reacting frame

    • Pillow block supports need to be machined (waiting on pillow blocks to arrive)

      • If pillow blocks are taking too long to arrive, let's machine anyway?

• Load Frame (Jorge)

  • • Machine holes for the two bottom load frame plates

    • Cap Screws

      • Need 2 cap screws

      • Machine cap screws

      • Get them to Greg to put on strain gauges

    • Machine Delrin/Teflon/Nylon blocks for top load frame plate angles

      • We have obtained scrap material, let's get the sizing and start machining

    • Machine top load frame (waiting on pillow blocks)

      • If pillow blocks arrive a bit later than assumed, let's machine anyway?

    • Machine top load frame plate angles

    • Assembly load frame with blind pop rivets

• Drive system (Brandon and Jerry)

  • • Order parts for the motor mount assembly

      • Angles, aluminum plate, wire

      • Machine necessary motor mount

    • Need wiring for the motor and motor controller (pick up from Graingers)

    • Test motor and motor controller (wire things up and write a simple program)

• Bearings (Jerry)

  • • Check up on order status, how many more days til they arrive?

Resources or Information Required but not Available

Schedule

• • Complete Support Structure (self-reacting frame) by Tuesday

  • Test Electronic components (motor and motor controller) before end of week 8

  • Will aim to complete test rig for testing by end of week 8

Budget (list amount spent and amount remaining)

Progress on Report and Webpage

• • Website

    • Updated Multimedia page with pictures of completed load frame
