Impact resistance test and Slackline Jumpline

To complete our testing in independent laboratory MECASEM that achieves standardization tests of our equipment, we completed our studies on the behavior of the slackline equipment and Jumpline because current tests do not represent fairly the reality of the practice in a Using slack or jump.

Presentation and explanation: 

The current machines we use are the same as in climbing or PPE Pro. Their tests are therefore based on several tensile tests which will break up. But in the slackline made; this is especially shocks repeated between produitent by slackeur vibration, wind, .... 

And Jumpline it is worse, because the jumpeur seeks to increase the amplitude of the trickline and therefore produces more violent changes. 

Thanks to the engineers we work with we could draw a parallel with the fasteners car trailers, which as Jumpline are subject to repeated shocks between acceleration and braking and especially in the same order of magnitude; of forces between 5 kN and 30 kN can be considered equivalent. As Jumpline entire force is applied mainly to one axis (bolt). . Various studies in this environment led to several standards. 

The standard that interests us is that the connection bolt and the side decks, it imposes a minimum resilience with a Rockwell of C33 fullest. 

To simplify: Mechanical resilience of materials characterizes the material's ability to withstand shocks, that is to say, to absorb energy and release it. plus Rockwell is low (<C1) more it can release energy without breaking and returning to its original state (eg rubber) by the most against the opposite Rockwell will be high (> C80) will be more less brittle and it will return to its original state and therefore will degrade with each shock and it will break the net. 

This eliminates the use of aluminum in mechanical parts to make the strength of the assembly, aluminum Mechanical with Rockwell C40 to C53.
