摘要： A method for providing information related to the compaction state of a soil when performing a compaction operation with a soil compactor comprises the operations: a) detecting a vertical acceleration and a horizontal acceleration of a vibratory roller when moving a soil compactor over a soil to be compacted, b) determining a measurement relationship between a ground contact force (Fb) and a deflection (sw) of the vibratory roller for one vibration cycle using the vertical acceleration and horizontal acceleration detected in operation a), c) determining a simulation relationship (ZS) between the ground contact force (Fb) and the deflection (sw) for one vibration cycle using a ground model taking into account at least one simulation parameter, d) comparing the simulation relationship (ZS) to the measurement relationship, e) determining that a default value of the at least one simulation parameter taken into account in the ground model substantially represents a corresponding soil parameter of the soil to be compacted when the simulation relationship (ZS) substantially corresponds to the measurement relationship.

摘要： A fastening device for hoses including two fastening parts two fastening parts adapted to be joined with each other and each having at least one recess which, in the joined state of the fastening parts, form at least one passage for at least one hose. The fastening parts are each formed by a fastening body with an elastic fastening component, wherein the fastening body has a lower elasticity than the elastic fastening component. The elastic fastening component respectively forms a recess surface in the recess. The elastic fastening component is molded to the fastening body to form a chemical bond with the same.
