Week 8

(2/27/12-3/2/12) 

1. Overview of Status of Analysis, Design, Fabrication, Test, etc

   • Finalized design

   • CADed up in SolidWorks for fabrication

   • Studied motor control system

     • For more information, we will be speaking to the expert in Delta Design about the control system

   • Put the order in for the materials

     • Ball bearings

     • Precision steel rod

2. Goals for next week

   • Fabrication

     • Finish inside assembly

       • Inside housing

       • Platform

     • Welding

       • Scheduled an appropriate time with Tom to weld center rod to the flange

   • Meet with sponsor and an engineer for control system 

     • Need more information to run the motor

     • Currently, all the wires are connected; however, the motor does not work

   • Finish up SolidWorks and AutoCAD model

     • Run Finite Element Analysis on assemblies

3. Instructor comments from last meeting and actions taken

   • Simulation

     • Came up with simulation for Proof of Concept model

     • Matched with our final design to prove the our model works

4. Risks and areas of concern

   • Control system

     • Turning the motor is the main concern

     • Controlling to meet the functional requirements

       • Speed and position accuracy

   • Linearity of the center rod mounting

5. Schedule

   • Finish up fabricating inside assembly

   • Model analysis on SolidWorks

6. Budget

   • Risk Reduction and scale model: $215.20

   • Steel Rod and Ball Bearings: $104.77

   • Materials: $843.47
