- 3. INTRODUCTION & MISSION STATEMENT Last year’s team Mission Statement: • To simulate a long shooting distance (up 90 M) within indoor range space (18M) to validate emulation methodology & algorithms with proof of concept • Designed a model that could emulate different ranges based on an algorithm. This Years Mission Statement (produceability & affordability): • Design shippable, transportable, lower weight/cost & easily assembled stand that addresses identified issues with last years final prototypes
- 4. REQUIREMENTS & DESIGN SPECIFICATIONS Requirements (Carried over from pervious year): • Emulate 18-90m shooting distances • Collapsible & Portable • Utilized scaled emulation target faces Design Specifications/goals: • Manufacturability: Cost-Effective, simple design, easy to maintain. • Affordability: Competitive sale price, minimum storage space & weight. • Transportability: Fit to standard shipping, resistant packaging, and lightweight. • User-Friendly: Easy of setup and, easy to move around, simple to repair. • Operational Safety: Minimize hazards, maximize structure factor of safety. First team goal: prove concept, our goal: make cost effective X 122 cm 50 M at 18 M 122 cm 60 M at 18 M X X 122 cm 70 M at 18 M
- 5. EVOLUTION OF EMULATION STAND DESIGN • Design approach evolved from original stand R&D efforts to increasingly higher fidelity deign solutions over two team life span Design evolution critical to developing optimized design solution Team 1 Phase 2014-2015 Team 2Phase 2015-2016 Team 1 interim Phase summer 2015
- 6. PROJECT SCHEDULE 201 5 201 6 All key schedule milestones were met
- 7. PRINCIPAL DESIGN REQUIREMENTS Top Case: • Shelving units with two pulleys on top shelf Target Cage: • Cage frame developed from shelving units • Maintains stability during operation by 8 wheels on each corner guided by the main frame corner columns Bottom Cage: • Four wheels mounted at the bottom of the cage for mobility • Particle board where Target Cage sits Motor: • Winch motor used along with pulleys to drive target cage position Design & Analysis performed utilizing SolidWorks
- 8. CRITICAL ANALYSIS AREA • Buckling of support stands • Tipping Angle of fully erected stand • Deflection (Induced by Tension of Target Cage) resulting in biding & resulting destruction by winch • Ability to fit into max UPS& FedEx shipping limits: Weight: 150 lbs (70 kg). Packages: 165 inches (length and girth combined) Packages: 108 inches in length. • Use of SolidWorks Key to success Failure to solve any key issue would have doomed design
