Damping Element K1 and Spring Rate K2
The compression properties of, for example, muscle tissue to fat tissue or to surfaces of the body
less covered such as fingers differ. Also, the biofidel property related to the pain sensation and
the injury risk is different. The body resistance must also be taken into account.
Biofidel setup
To create a biomechanical or biofidelic setup, specified compression elements K1
and K2 have to be used.
■
The damping elements K1 simulate the biomechanical property of body
surfaces.
■
The spring rate K2 simulates the biofidelic body resistance.
The K1 damping elements are classified by Shore hardness. Colors are assigned to the diffe-
rent Shore hardness. The correct damping element is determined by the color:
Color
Shore-hardness
Green
10° Shore A +/- 7
Blue
30° Shore A +/- 5
Red
70° Shore A +/- 5
The Shore hardness of the K1 damping elements can change with aging. The manufacturer
recommends replacement after one year as part of the calibration service.
If the K1 damping elements are exposed to special conditions such as high ambient tempera-
tures or contact with solvent containing liquids, it may be necessary to replace them earlier.
Spring rate K2
The K2 spring rates are special springs built into the CoboSafe CBSF force sensors.
They enable a correct simulation of the biofidelic body resistance. The springs (K2)
of the manufacturer are all tested for suitability and are subject to strict selection
criteria.
