Vibration tests (sine,random...)

The sine tests

Vibration tests The vibration tests often form part of the real mechanical environment.

The sine vibrations are relatively rare in the real environment. They are mainly encountered near rotating machinery, during the phases of start up, shutdown or regime change.

Objectives

  • Characterize and / or perform a modal identification of a material
  • Realize a vibratory reference signature
  • Apply a specification defined in a normative document to demonstrate the robustness of a material
  • Apply a specification after real measurements to validate the required equipment

Random tests

By nature, the actual vibration environment is random (excitation of all frequencies of a material simultaneously).

The vibrations occur on launchers, road vehicles, ships and aircraft.

Objectives

Apply a specification defined in a normative document to demonstrate the robustness of a material.Apply a specification after real measurements to validate the required equipment.

The sine/noise or noise/noise tests

These tests consist of applying in the same time, 2 types of vibratory instances representing the real environment of equipment.

Objective

  • Apply a specification defined in a normative document to demonstrate the robustness of a material
  • Apply a specification after real measurements to validate the required equipment

Constant acceleration tests

Vibration tests (sine,random...)These tests involve applying material to a fixed value representing the acceleration of real environment.

Our facilities

To perform this type of tests Intespace has 6 facilities of electrodynamics' shaker type:

  • 3 facilities of 67 kN, 80 kN and 160 kN (Fourier area) dedicated to equipment / small systems able to acquire 16 channels, 44 channels and up to 120 measurement channels depending on the needs
  • 1 installation of 27 kN (Clement Ader Zone): dedicated to non-space equipment (no class 100,000) and associated with 16 control channels / actions
  • 2 facilities of 320 kN in vertical and transverse configurations (D-zone Pascal): dedicated to subsystems/ systems able to acquire up to 400 measurement channels according to the requirements.

Specific tests for constant acceleration are achieved using a centrifuge with a maximum acceleration of 270g and a maximum speed of 600 rpm.
