Agenda for the review• Overview of the Project

• What are we trying to accomplish?

• Our system designs• Math/ computer modeling to show our concepts were valid• How the system will be integrated

• Part designs• 3D modeling• Analysis results

• Lab View layout• Bill of Materials

• What are we building vs buying

• Test plans• Risk Assessment• Schedule for the rest of the Project

Problem Statement

To mass spectrometer

UUT

High pressure helium

High pressure helium

Fixturing/leakage similar to other side

Fixtures interface between AGT can and UUT

Fixture leakageUUT leakage

Leakage from Unit UnderTest

Leakage from Fixture

Leakage from room through lid and baseplate

5

Project Overview

6

Our system ideas• Simulink modeling

• Graphs showing the amount of He over time• Prove our ideas generated in the last review

7

System Layout

8

Enclosure

9

Pipeline model

Some type of relief structure will be in place here

Wires exit rear

10

Mounting to the can

11

Through the Manifold

12

Port Blocks

13

The Plug

14

Mounting to the side of the can

15

LabView Layout

16

Wire Diagram

Each valve has 2 leads for a circuit. They will be connected to a terminal block and then to a terminal block on the AGT system

17

Bill of materials• What do we need to buy

• Who is responsible for each purchase

18

Test plans• How they related to the engineering specs• When/ how we plant to test

Action to Minimize Risk Owner

1 Concept ideas do not workStart over, beg to have some constraints l ifted, Concepts do not fit Moog constraints 1 3 3

Pay attention to constraints, leave room for error team

2 Complexity is too high

We wont be able to find a concept idea that would work successfully.

We do not have the suffi cient skil ls to solve the problem on our own. 2 2 4

Do enough research and analysis and talk to experts l ike professors specialized in those areas. Eileen

3 Can't physically test conceptWe don’t know if the system actually works or how well Moog is in buffalo 2 3 6

Build a working model and have constant communication Marie

4

Parts do not arrive on time or purchased parts are not what we ordered

Schedule is affected, we possibly do not meet deadline Vendors/Moog have high lead times 2 2 4

Constant communication and good specifications/ research lead times before purchase Ana Maria

5Mechanical failure post manufacture

No physical product for customer Manufacturing error 1 3 3 Marie

6 Bad design 1 3 3 Design reviews, annoys, cad modeling, Austin

7Customer requirement or priority changes

Scope changes, schedule issues, go over budget and we would need to justify it

Economy plummets/ internal priority shifts 1 1 1 cant Marie

8 Software Bug Doesn’t workPoor design and not experts in Lab view 1 1 1

Verify with experts in Lab view and have a comprehensive layout for what we want Labview to perform Austin

9High pressure gas gets into the vacuum system

damage to the lab's vacuum system

heavily damaged/ missing O-ring or some sort of system bypass 1 3 3

insert burst disk before vacuum system entrance Marie

10High pressure gas gets into the 3-way valve

damage to the valve and the Nitrogen supply system

heavily damaged/ missing O-ring or some sort of system bypass 1 3 3 insert burst disk before the valve Marie

11All system components wil l not fit into the desired space

parts not organized/ cannot access them as needed

parts ordered do not fit as well as planned when actually mounted 1 1 1

plan a layout and purchase parts so that they fit into the assigned electronic shelving space Marie

12System parts do not work cohesively together

the system cannot perfom as desired parts are poorly designed 1 3 3

model the designs together and run through some finite element analysis Ana Maria

13purchased parts are not integrated with the designed parts 1 3 3

research as much information as possible for each purchased part to be sure it corresponds to the existing system Ana Maria

14Team disconnect over the "off" quarter

Have to spend unnecessary time re-learning the project

lack of preparation for the "off" quarter 1 2 2

take well documented notes during the fall, and keep each other (team members, customer, and guides) updated throughout the winter Eileen

Our schedule going forth….winter and MSDII
