Testing With Vibration

From circuits to welds, testing is necessary to ensure that products are able to withstand the environment where they will be used. With industrial vibrators, testing engineers can adjust the frequency and amplitude of the vibration, as well as length of time a test is conducted. This provides the flexibility needed to test a wide range of products under a variety of conditions.

At NetterVibration, we produce high-quality vibration equipment engineered to perform a wide range of industrial tasks, from testing products for vibration and shock tolerance to sorting products accurately by size and weight.

Optimisation the length of pile groynes

As part of a case study in a research project, our customer examined the ideal length of wooden breakwater posts which are to be embedded in the sand, protecting the beach against coastal erosion. The goal was to reduce the length of the piles to a minimum in order to reduce the amount of material and energy used. At the same time, the wooden piles should be stable enough to withstand the swell.

As there was no possibility to use the sensitive measuring devices required in salty seawater, the piles were set on the waterfront. The customer used a pneumatic linear vibrator series NTK 25 fixed on the piles to simulate the force and frequency of the ocean waves. In this way, the long-term effect of the swell could be successfully replicated.

With the knowledge gained, the consumption of wooden piles can be reduced to a sustainable level. The reduction of resources, energy and time necessary to install the piles, that are too long, is also very beneficial for the environment.

Products used in this case study
  • pneumatic linear vibrators series NTK by NetterVibration
    Series NTK Pneumatic Linear Vibrators

    The pneumatic linear vibrators of the series NTK are especially suitable for conveying and compacting bulk material, due to the completely linear vibration. The linear vibration is produced by a freely oscillating, self-reversing piston.

Vibration Simulation

A research institute required our service to help develop an active suspension for the automobile field. The target was to simulate the movement produced from the engine in order to compare the results acquired by calculation. To ensure the success of the project the test had to be carried out under ideal conditions. That means, simulation of the oscillations could be produced on different axes or uniquely on one axis.

By applying the VectorDrive multiple-shaft vibration system, also known as PowerCube, this simulation could be reached. The PowerCube is able to generate oscillations exclusively on one axis, whereby the forces on the other directions remains null. In this case, the PowerCube produces forces of up to 20 kN with an adjustable frequency of up to 200 Hz. Furthermore, the PowerCube is able to produce a specified amplitude. This flexibility allows engineers to closely match a wide range of actual driving conditions, allowing accurate prediction of the equipment’s performance in use.

Products used in this case study
  • multiple-shaft vibration system VectorDrive by NetterVibration
    Series VectorDrive Multiple-Shaft Vibration Systems

    The multiple-shaft vibration system VectorDrive offers a multitude of application possibilities. The resonance-free starting and stopping, together with independent regulation of the working direction, frequency and amplitude open up new possibilities for compacting, mixing feeding and distributing.

  • [Translate to English:] Serie NEG Drehstrom Elektro-Außenvibratoren
    Series NEG 3-Phase Electric External Vibrators

    Electric external vibrators of the series NEG are used whenever, for example conveyor chutes or sieves need to be driven. In addition, these devices can loosen material blockages adhesion in silos. The 3-phase NEG units run at 750, 1,000, 1,500 or 3,000 min-1 with a 230/400 V, 50 Hz power supply.

  • static adjustable frequency control SRF by NetterVibration
    Series SRF, NFU and ATV Variable-Frequency Controls

    Some applications require frequencies that cannot be achieved with normal vibrator. We offer three types of variable-frequency drives solutions.
