For Nike zoom air cushion works well because of its official no technical details were released too much, so we can only speculate based on their analyzes.
Currently popular on the Internet is a saying i Retro jordans for sale s this:
Everyone knows zoom air is by air and in the middle of the fiber to shock, but it's exactly what mechanism?
First, the structure is a zoom air cushion flat, then the middle of many of nylon fiber, with a flat top and bottom ends of the fibers of a fabric, may be up and down the inner wall of the way with hot air cushion is fixed.
direction due to the expansion of gases and other properties, zoomm air cushion has a tendency to form spherical, an d nylon fibers will stretch into a tight state, thereby forming a balance, so that it can be maintained at such a thin thickness (a typical thickness of 8mm ), whether it is the will drum up.
form nylon fibers are basically two:
However, these nylon fiber in the end is how the shock of it? You must start thinking like me, thought it was a nylon fiber own rebound. That's so long ago I found weird place.
For example, do not we hold a dental floss to st cheap jordan shoes for men raighten it, and this time it is with zoom air in tight nylon fibers exhibit the same state, when it forced to the middle pressure, what will happen? direct soft off, would not have to play the two ends is not it?
That zoom air in the end is why this resilient it? A safe is actually very simple, you have learned when I was young, that tension.
Let's look at the usual zoom air:
when it is under pressure from the upper and lower ends, the position of t cheap jordans for sale he force will be like nylon fiber floss as weakness, loss of tight state, while its upper and lower surfaces of the shorter distance, but the focus is outside the force position nylon fiber:
As shown in the figure, since the force receiving portion by the volume reduction, this position would have been in the air is pushed to the other parts, resulting in an increase in pressure unstressed position, volume expansion, the nylon fibers are stretched, i.e. Retro jordans for sale not force receiving portion is elongated.
is stretched nylon fiber tension will increase, than the original equilibrium value is also large, because the distance is short, so it should be able to remain within the elastic deformation range.
When the power over the maximum after (you can imagine the force into the normal curves), the larger tension will force the back to the original nylon fiber length and size down to balance the tension on duty, so Volu Cheap air jordans for sale me unstressed portion will reduce, and the air force to squeeze section, then the original parts of the force of the pressure will increase, resulting in an undershoot power up, this is what we feel the stretch.
mechanized full terms, zoom air cushion itself, already has a cushion property cushion shock, but the middle and lower ends fixed joined nylon fiber support material, in the shock absorbers, the fiber itself is stretched by the increased tension , cheap foamposites you can prevent the force part continue to shrink, so can zoom air in such a short distance, providing a very excellent shock absorption, followed in order to increase the tension force the fiber length back to equilibrium state, squeezing the air so The original parts of the force of the pressure increase resilience, so it also has to make amazing flexibility and feedback.
If you shock the principle of common air of view (first ignored will complicate mat cheap jordans online ters in the end), it is largely unaffected by increasing the volume of parts of the force, the tension generated by the expansion of the plastic skin to provide a response Flexible.
zoom air in addition also has a plastic skin tension, but also increased the number of nylon fiber, so it will be excellent elastic response rate than ordinary air, its essence is that the tension between the use of nylon fibers and fight each other to adjust the air pressure t cheap jordans for sale mens o produce the role of shock absorbers and feedback.
