METHOD FOR DETERMINING THE STIFFNESS AND/OR DAMPING OF AN AREA OF A PHYSICALNESS
The invention relates to a method for determining the soil stiffness (kB) of a soil area (2). For this purpose, a vibration-excited contact body (6, 8) of a soil compacting device (1) acts on the soil surface (9) in such a way that there is uneven loss of contact (jumping) between the soil surface (...

| description | The invention relates to a method for determining the soil stiffness (kB) of a soil area (2). For this purpose, a vibration-excited contact body (6, 8) of a soil compacting device (1) acts on the soil surface (9) in such a way that there is uneven loss of contact (jumping) between the soil surface (9) and the contact body (6, 8) while the soil surface is acted upon. While the soil surface is acted upon, parameters (f) of the vibration excitation and parameters (xd) of the vibration response (xd) of the contact body (6, 8) are determined, and the soil stiffness (kB) is calculated from said parameters in combination with known parameters (mu, ru, md) of the soil compacting device (1). By means of the method according to the invention, it is possible to reliably determine the soil stiffness (kB) even in an operation with uneven loss of contact, so that it is sensible to equip even unregulated compacting machines, such as simple vibration plates, with corresponding measuring and evaluating electronics. |
