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