Assessment of Knee Cartilage Stress Distribution and Deformation Using Motion Capture System and Wearable Sensors for Force Ratio Detection

Figure 2

A simplified spring-damper-mass model used in the computer simulation. The components of the dynamics system presented are lower body rigid mass () and wobbling mass (), upper body rigid mass () and wobbling mass (), compressive spring () and damper () that connect the upper and lower rigid bodies, spring () and springdamper unit connecting the lower wobbling mass to the upper and lower rigid bodies, and spring and springdamper unit connecting the upper wobbling mass to the upper rigid mass (adopted from [12]).
