This document describes an optimized dynamic archery emulation training system designed by a team of students. The system aims to simulate shooting distances between 18-90 meters within an indoor space of 18 meters. The team improved upon last year's design to create a lower cost, portable, and easily assembled stand. Key aspects of the new design include using off-the-shelf components like shelving units, reducing weight to under 150 pounds, and ensuring the disassembled system can fit within standard shipping dimensions. Testing validated the design meets requirements for simulating different shooting distances, portability, and affordability while maintaining structural integrity and safety.

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

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

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
