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.
