Speed limit curve (in the closing direction*)
*SIDOOR ATD4xxW: Opening and closing directions
The speed limit curve is the characteristic that determines the maximum permissible door
speed (closing speed), v
max
, as a function of the total door panel weight. According to EN 81,
the maximum kinetic energy of the door in the closing direction must not exceed 10 joules.
W
KIN
= 1/2
m ∙ v² = 10
J.
Example from the following speed limit curve:
●
Total door panel weight m = 180 kg => v
max
= 0.33 m/s.
