P19310: LORD Vibration Isolator/public/
Customer Handoff & Final Project Documentation
Team Vision for Final Demo and HandoffSummarize:
- complete remaining test plans from last phase
- receive customer confirmation from LORD.
Results Quality and Quantity
- Marginal value for difference in coupled versus un-coupled vibration reduction increased from 5% to 10%, lower value was unrealistic with smaller baseplates “sliding” on table
- Average input frequency is well within marginal. Motor control creates some “lurching” frequency jumps, but are still within +/- 1Hz margin
- Vibration generation method remained unchanged from P18310, previous testing for acceleration in y/z-directions deemed acceptable
- Accelerometer model unchanged from P18310, spec for accelerometer resolution is an order of magnitude smaller than marginal
- Accelerometer calibration accounted for in MATLAB code, warning produced when offset differs significantly from nominal
- Vibration reduction averages around 60% in ideal conditions (command strips, sturdy flat table). Can vary +/-10% based on condition of command strips
- Temperature test data not added to test plan; previous testing shows steady state at 85°C.
- Maximum operational time limited by micro-mount life; should be 8+ hours with average TVA displacement

Risk and Problem Tracking
- Other than the live plotting constraint issue that was highlighted earlier, no notable problems remain. All problems from the previous phase were addressed to a level deemed acceptable to meet the engineering requirements.

- Unexpected problems can and will occur any time. Planning for these problem ahead of time would have been a plus.
- Subject matter expert opinion on the feasibility of some of the requirements would have been helpful.
- Allocating time for shipping and machine shop delays can be make a difference in meeting deadlines.
- From this phase, drawing tracking chart and distribution of work through planning spreadsheet helped with deadlines and communicating expectations.
- from the whole project, the team learned a great deal about the various project management tools, including planning and task distribution, communication strategies, and the problem solving method (root cause identification)
