  • Arrangement for providing a pulsing compressive force
    Patent number: 8727660
    Abstract: The invention relates to a soil compacting device having an exciter part (1), which has an unbalance exciter (2) for producing an intermittent exciter force and a contact surface (3) for transmitting a force component of the exciter force directed perpendicularly to the contact surface (3) to the soil surface (4) to be compacted as a pulsing compressive force. The device also has a vibration damper part (5), which is connected to the exciter part (1) by means of a spring-damper unit (15). The spring stiffness of the spring-damper unit (15), the damping of the spring damper unit (15), the spring pre-load of the spring-damper unit (15), the mass of the vibration damper part (5), the mass moment of inertia of the vibration damper part (5), the mass of the exciter part (1), and/or the mass moment of inertia of the exciter part (1) can be varied during operation.
