**v2.02.107** SDLL107 - Transient calculation of a beam under random excitation
=================================================================================

**Summary:**

The objective of this test case is to calculate the temporal response of a beam under random excitation with a power spectral density (DSP) and whose movements are limited at several points by obstacles:


* The beam is subject to random solicitations,


* The obstacle is characterized by a normal shock stiffness and a coefficient of friction.

At the level of obstacles, several variables characterizing the behavior are determined:


* Average travel,


* Value RMSde the normal force,


* Average value of the tangent force,


* Wearing power

This test is carried out on a beam composed of SEG2 elements and a circular cross section.
