The present invention concerns a device for evaluating the surface condition of a material and a method derived from it, based on the use of an element which vibrates under the influence of relative movement with respect to the surface to be assessed. This method allows the analysis of any surface, with or without surface periodicity, regardless of its constitution or its composition, and regardless of any surface treatment(s) it may have undergone. The evaluation device (1) comprises a support (2) to which is attached at least one vibrating element (3) capable of vibrating upon contact with the surface of the material surface (5), the vibrating element (3) being driven to move relative to the material surface (5). The evaluation device (1) also comprises a mechanism (4) for measuring the particular vibration modes by the vibrating element (3) which furnishes a signal corresponding to said particular vibration modes, a device (6) for processing and analyzing the signal which produces one or more elements of data characterizing a surface condition, and an interface (7) which displays the one or more elements of data.
A device (1, 10, 20, 30) for evaluating the surface condition of a material (5, 15, 25, 35), characterized in that it comprises a support (2,12, 22, 32) to which at least one vibrating element (3,13, 23, 33) is attached and which is capable of vibrating upon contact with the surface of said material (15,15,25, 35), said vibrating element (3,13, 23, 33) being driven in movement relative to said surface of said material (5, 15, 25, 35), a means (4, 14, 24) for measuring the particular modes of vibration by said vibrating element (3, 13, 23, 22) which furnishes a signal corresponding to said particular modes of vibration, a device (6, 16, 26) for processing and analyzing said signal which produces at least one element of data corresponding to said signal to characterize the surface condition, and an interface (7, 17, 27) to display said data.
An evaluation device according to any one of the preceding claims characterized in that it comprises a housing (21) protecting said vibrating element (23) and said support (22), said housing (21) comprising at least one opening (28) for the passage of a portion of a said vibrating element (23).
A method using the evaluation device according to any one of the preceding claims characterized in that said evaluation device (1, 10, 20, 30) is placed in motion relative to said material (5, 15, 25, 35) so as to cause said vibrating element (3, 13, 23, 33) to vibrate;
