  • Do's and Don'ts of Concrete Vibration

    Formwork vibration: Formwork vibration is commonly used in precast concrete construction and involves mounting the vibrators to the outsides of the concrete forms.For larger pours, the external form vibrators are often spaced 6 feet apart. Surface vibration: With surface vibration, large vibrators (sometimes called "jumpers") are directed manually onto the surface of the poured concrete.

  • Understanding of resonance essential for solving .

    Resonant vibration in mechanical structures such as pumps, turbines and motors occurs when a natural frequency is at or close to a forcing frequency such as rotor speed. When present, this condition can cause severe vibration levels by amplifying small vibratory forces from machine operation. Such problems often develop after a speed change has been implemented, as with retrofitting a machine ...
