DIN Settings and Springs

post #1 of 2
Thread Starter 

Over the few years that I've been in this group there have been several DIN setting threads, some of which had heated opinions (and rightly so).  The primary issue seems to be that how the mechanism of a binding is designed and implemented plays a big role in how comfortable skiers are with the DIN setting chart and the issue of hold and pre-release.

 

One of the biggest factors least discussed is the springs (other than failure and off season settings) on bindings.

 

To gain some understanding I'll suggest that you read:

 

Spring Designer's Handbook by Harold Carlson

ISBN 0-8247-6623-7

 

Particularly Chapter 11 Compression Springs, which includes indirectly, a cause for pre-release is explained in part by the Vibration, Natural Frequency and  Surge section.

 

Additionally for failure read, Chapter 10 Fatigue Failure; Recommended Design Stresses.

 

I am sharing this as a FYI and use at your own discretion format as some of you diehards out there may have nothing better to do while waiting for snow  :D

I'll check that out as soon as I finish the issue of Modern Tire that Philpug recommended in another thread.
