Table 1 Definition of force–time profile characteristics
Force–time characteristic | Definition |
|---|---|
Preload force, N | Local maximum, delimited by T0 and T2 |
Release force, N | Force at T2 |
Δ Preload and release force, N | Force at T1–Force at T2 |
Peak force, N | Force at T3 |
Thrust force, N | Force at T3–Force at T2 |
Maximum thrust speed, N/s | Maximum of first derivative of the force time-profile |
Rate of force application, N/s | (Peak force–release force)/thrust duration |
Thrust impulse, Ns | Area under the curve from T2 to T4 |
Preload duration, ms | T2–T0 |
Thrust duration, ms | T3–T2 |
Resolution duration, ms | T4–T3 |
Total duration, ms | T4–T0 |
