I am trying to model a foot as a mass-spring-damper system in free vibration. I have done impact tests and am trying to get the model to match the experimental data. I have tested the foot using several different deflection rates quasi-statically to get an equivalent spring constant function. From this spring function, I can use the normal underdamped equation for x(t) and then calculate the velocity and acceleration to get the Force. I am having trouble getting my results to compare to the impact tests (data includes force-time). Does anyone have any ideas on what variables I can change besides the quasi-static test rate or time step (found that didn't work)?
