1 Brandon Robinson Danut Tabacaru Victor Ho Autonomous Spacecraft Impact Monitoring Preliminary design presentation Autonomous Spacecraft Impact Monitoring Preliminary design presentation

2 Project overview Test plate set up with strain gauges and transducers Phase 1: Impact force magnitude and direction detection Phase 2: Damage detection and analysis Phase 3: Damage repair

3 Budget update *Denotes total cost including items purchased using OCE and in-house funding.

4 Hardware update (1) Test Plate 14.5” x 14.5” dimensions 1/16” thickness Industrial grade 6061 aluminum Frame Aluminum pieces cut from dry-wall frames Frame attached to edges of plate so that a 12” x 12” area of the plate is left unsupported Test Plate and Frame

5 Hardware update (2) Strain Gauges Vishay 240UZ Low Cost 0.24” gauge length 4 per side layout – 16 in total Data Acquisition NI cDAQ-9174 chassis NI 9235 8-channel quarter-bridge strain gauge modules Vishay 240UZ

6 Hardware update (3) Transducers Pulsing Circuit Amplification 555 Timer Transformer Coil Voltage Ladder Pulse 555 Timer Class C Amp Class A Amp Amplified Pulse Pulsing Circuit

7 Hardware update (3)

8 software update Software MATLAB LabView Measurement Studio NI Measurement Studio Included drivers GUI, Analysis, etc. Visual C++ Modular Calibration Force and Position Block Diagrams

9 Modeling update ANSYS 10.0 Analytical model using FEM Modeled using Aluminum 6061 properties Shell 8node93 Provide a baseline for physical model Test plate modeled in ANSYS

10 Risk management Project is spaced out into phases Phase I – Essential Phase II – Possible Phase III – If time permits Accuracy can be reduced Budget remaining

11 Milestone update
