Formula for calculating the Resilience of BW-Fixators® Serie S
애m 욼F = Load change
g N
욼ff애m =
c Spring constant N/애m
Note:
The total of the forces a - e exerted must not exceed the permissible maximum load
a) Proportional machine load
b) Tensile force exerted by anchor bolt
c) Dynamic forces
d) Changing loads (moving machine parts or workpieces)
e) Forces counteracting moments
