Laboratory equipment

On this page, you will find information about the equipment in the Machine Dynamics Laboratory.

Among other things, state-of-the-art measurement technology and various devices for inducing vibrations are available.

PSV-500 Vibration Measurement System

Non-contact, full-surface measurement of vibration modes.

Unlike adhesive-mounted accelerometers, the scanning vibrometer performs precise measurements regardless of the component’s geometry, surface, or dynamics. This is made possible by laser-assisted scanning of the component.

To identify a component’s vibration behavior, the system offers the ability to visually display the resulting vibration modes.

Experimental modal analysis with M+P Analyzer

The M+P Analyzer precisely captures vibration signals and analyzes them in both the time and frequency domains. Using FFT analysis and transfer functions, natural frequencies, mode shapes, resonances, and damping characteristics can be reliably determined.

Three modal hammers of different sizes are available for experimental modal analysis. This makes it possible to perform metrological measurements on everything from the smallest electronic components to large structures—including buildings.

Shaker

To induce vibrations across a wide frequency range and at high accelerations, the Machine Dynamics Laboratory uses a variety of electromechanical shakers. The laboratory is equipped with the following hardware and software, among other things:

Sliding Bearing Test Bench

Sliding Bearing Test Bench

Tribological tests are conducted on a custom-designed test bench that is specifically tailored to the geometry of sliding sleeves. The test system is based on the C2 method in accordance with DIN ISO 7148-2. The sliding sleeves are mounted in a pendulum device and are supported on one side by a motor-driven shaft. The load is applied via defined test weights (0.5 kg / 1.0 kg / 2.0 kg), which are transferred to the test specimens via the pendulum mechanism. Friction is measured non-contact via a laser sensor that measures the horizontal deflection of the pendulum arm. The coefficient of friction is calculated based on this measurement.

NV-Tech SAM Automated Modal Hammer

In addition to the shakers, a modal hammer is also used to induce vibrations. To assist the user, the striking motion is performed by a controllable stepper motor, enabling consistent and precise strikes.

Simulation using FEM software tools

At the Laboratory for Machine Dynamics, simulations using finite element models (FEM) are performed with the Abaqus and COMSOL software packages.
These programs are used to virtually replicate and simulate test setups. By comparing the results with experimental data, simulation models can be validated, allowing predictions about component behavior to be made in subsequent virtual tests.
Furthermore, FEM software is useful for making statements about component properties early in a development project without having to produce a costly prototype.
