Sensation of Friction
When investigating a door system, it will become obvious that the sensation is not only determined by the impact energy it requires to latch, it depends equally on the sensation pushing it out of the detent and get the door moving. It doesn t take much effort to observe that excessive fiction in the hinge or check clearly degrades the sensation of quality on a door system.
How to Measure?
A friction measurement is not obvious, especially if it is a result of different components that at the same time also have a speed dependency. The new algorithms reduce these effects to an easy to determine loss of kinetic energy. A short version is basically the speed at which the user pushes the door and the eventual speed the door has right before impact. The loss of kinetic energy is representative to the loss of energy due to friction. The advantage of this method is that it can be part of the same manipulation to establish Minimum Closing Speed.
