vertical safety, net system, simplified model, mathematical modelAbstract
The first part of this paper (2) analyzed the behaviour of the spanish vertical safety net system, in view of the results of some previous experiments and predictions of a simplified mathematical model.
From the first provisional conclussions there included, the subsequent research lines were suggested, whose results are included in this part:
1st.) The execution of experimental tests with instrumented safety devices to confirm and to precise the preliminar conclussions, and to calibrate a more complex mathematical model.
2nd.) The development of a numerical model able to implement the most important features of this safety system behaviour, and to come up a design tool
. These conclussions will allow to perform a safe and adjusted design for this vertical safety net system, and probably for other similar ones.
