Objectives Design, Build, And Test A Vibration Suppression System To Counteract Launch Vehicle Vibrations Measure The Vibration Environment Inside The Terrier-Orion Rocket Will Use Two Identical Vibration Measurement Systems A Custom Built Passive Damping System Rigidly Attached System Compare The Designed Passive System Vs. The Rigidly Mounted Undamped System
Review Of Last Year’s Launch Data
Review Of Last Year’s Launch Data 1st phase boost 2nd phase boost Chute deploy Z High range acceleration Anomoly? Design problem is to reduce these spikes on both graphs
Review Of Last Year’s Launch Data
Benefits Efficient Vibration Isolation Systems For Small Payloads Increased Operational Performance Of Onboard Sensing Equipment Better Protection Of The Sensing Equipment
Concept Of Operations System Deactivated Flash Memory Activated RBF Wires Connected System Deactivated Flash Memory Activated Rocket Launch Level Translator Activated Payload Retrieval Microcontroller Activated G-Switch Activated Z Accelerometers Activated Rocket Splash
Structural Drawing
Final Payload
System Schematics Main Board Consists Power Supply System Basic Stamp Microcontroller External ADC, Memory
System Schematics Z-Axis Acclerometers Consists Of Hi-G And Precision Accelerometer
Structure Two Plates Containing Identical Electronic Equipment On Each Comparison Of The Designed Vibration System With That Of A Rigidly Mounted Identical Measurement System
Subsystem Requirements Power (For Each Identical System) Two 9V Lithium Ion Batteries Connected In Parallel Provides Continuous Power Throughout Entire Flight Voltage Regulators Will Step Voltage Down To 5 And 3.3V
