v5.02.301 SDNL301 — Vibration of a beam with multi-point impact

Summary:

The objective of this test case is to simulate the dynamic response with damping of a beam with multi-point impact:

• The beam is subject to sinusoidal stresses.

• Impacts (obstacles) have normal stiffness and normal damping.

• Only one POU_D_T modeling is done

The value RMS of the normal force at the free end is determined with or without taking into account static modes.
