User report 1: Controlling the vibrations of chill-molds (30 tons)

With company-specific know-how a production facility (see picture on the left) for the rotation of chill-molds for centrifugal casting was designed. Therefore, a cylindrical, empty chill-mold is put into rotation and is filled head-on with liquid metal two times. Because of the centrifugal forces, the metal flows to the inner surface of the rotating chill-mold and... more

User report 2: Less wear, more comfort by means of balancing

People who love to fly appreciate the boundless freedom high above the earth. However, unbalanced propellers can affect the fun in flying negatively: The vibrations acting on the pilot are experienced in an unpleasant way, vibrating instrument needles require... more

User report 3: Service provider balances a 30 MW generator

For the maintenance of rotating machines, companies like to employ external service providers. In the field of vibration measurement, -analysis and -reduction, VibroMatrix is a compact but powerful measurement system for engineering offices, which can be extended according to their demands. This report describes vibration measurements on a 30 MW generator and the successful vibration reduction by means of balancing... more

User report 4: 8000 tons of falling mass and nobody bothers

Industry creates values and jobs but nobody wants to experience a reduced quality of life in his/her residential area. If industrial and residential areas are situated closely together for historical reasons, vibration measurement and -monitoring help to optimize processes... more

User report 5: Ensuring occupational safety for pressure washers

If hand-held machines or workpieces transmit strong vibrations to the operator, a decreased performance and even diseases might develop. For this reason, the directive 2002/44/EC stipulates measurements according to ISO 5349, which determines the impact on the human hand-arm-system. In the case described now, a producer of high-pressure cleaning lances had to find out whether... more

User report 6: Avoiding damages on rolls

In many industries of our economy, the requirements for existing machines increase. The industry of building materials for instance faces the challenge to follow the trend towards elements which permit high energy savings. Our customer in this case was a brick producer. The processing of raw materials required a roll distance of 1 mm. Due to bearing clearance and wear, this gap... more

User report 7: Cut off problems - detecting natural frequencies

Constructional parts often are exposed to vibrations and dynamically stressed in consequence. If one cannot eliminate the vibration source itself, the constructional parts should at least have no natural frequency in the range of the excitation frequency. Otherwise resonant phenomena... more

User report 8: Protecting spine, wrists and nerves

Sedan cars stand out due to their excellent running smoothness and comfortable seat characteristics. In order to test these characteristics, the well-known expert organization DEKRA applies a VibroMatrix measurement system. Like health assessments, comfort assessments for exposure to whole-body vibrations are described in the standard ISO 2631 and... more

User report 9: Storm resistance for 200 tons in a height of 135 meters

Wind energy faces big expectations when it comes to carbon-dioxide-free energy generation. Established on land since many years, the white giants now conquer the sea.
Offshore, wind power plants are exposed to even more mechanical stress. By means of VibroMatrix... more
