Presentation Transcript

  1. Introduction to Biomechanics IE497 Spring 2009 Dr. R. A. Wysk

  2. What is Biomechanics? • The process of describing, analyzing and assessing human motion • Some focus on handicapped • Gate of motion • Joints and joint replacement • Stable and sustainable

  3. Examples

  4. Flow of joint position from a camera

  5. The Arm

  6. Joint Replacement Design

  7. An Elbow Joint

  8. Use a free-body diagram

  9. Free-body diagrams • Shows all forces and kinematic points • Draw a representative free-body diagram • Equilibrium mapping • Write the equations of static equilibrium • Solve/analyze the system

  10. Our diagram Theequations for static equilibrium are: SM = 0 SFx = 0 SFy = 0

  11. Our problem

  12. Hip Biomechanics
