Mountain Bike Rear Suspension David Harris Chris Polinsky Luther Beale Heather Landis Faculty Advisor: Dr. Chien Wern

The Process 1. What is the Goal 2. What are the Options 3. How do Concepts Compare 4. Selecting a Concept 5. Pros and Cons

What is the Goal Comfortable ride over varied terrain Minimize effects of rider inputs Provide a suspension that maintains a consistent level of efficiency

Concepts Linkage System Active Control System Motor Flexible Wheel Swing Arm System Flexible Member

CriteriaImportance (1-5) Performance5 Not pedal activated5 Adjustable3 Rearward Path3 Absorbs bumps5 Constant seat height3 Minimize chain growth3 Ease of implementation4 Ease of maintenance2 Light weight4 Ease of manufacturing2 Aesthetics3 Innovative5 PDS Criteria

Results of Concept Analysis

Final Selection Key Points Strengths –Multiple Axle Paths –Higher Performance Weaknesses –Chain Growth –Increasing Complexity with # of Links

Conclusion A Linkage Based Suspension System
