摘要： The invention relates to a method for determining the dynamic characteristics of materials, especially dampening properties of sheet metal coated with silencing material. The produced strip-shaped samples are fixed in a suspensory manner at one of the ends thereof. A continuous bending wave occurs by an excitation on the fixed upper end of the sample. Said wave can be measured and characteristics of the material, e.g. the dissipation factor, can be determined from the obtained data. Compared to known methods wherein stationary waves are produced and evaluated, the inventive method enables precise measurement of large dissipation factors up to very high frequencies.

摘要： A surface testing equipment comprises a holder for holding a specimen to be tested at a predetermined location; a test probe mounted for recoil movement away from the predetermined location in a predetermined direction; means for urging the test probe towards the predetermined location; means for oscillating either the holder or the test probe so as to cause, in use, repeated impacts between the test probe and a specimen; and means for monitoring the position of the test probe. The testing equipment is capable of being used for surface toughness testing or adhesion testing depending upon the nature of the specimen and the mode of operation of the equipment. One such method comprises the steps of: (a) mounting the specimen in a holder; (b) urging a test probe which is capable of recoil movement away from the specimen into contact with the specimen; (c) oscillating either the specimen holder or the test probe so as to cause repeated impacts between the specimen and the test probe; and (d) monitoring the position of the test probe whilst the specimen or the test probe is being oscillated.

摘要： The invention relates to a device for measuring the surface hardness of rolls (2) of paper or other material. Said device comprises at least one hardness measuring head (12) with at least one rotatably mounted contact roll to rest, under radial pressure, on the revolving roll (2) of paper or the like. The hardness measuring head (12) can be moved on a rail (11) substantially parallel to the winding axis of the roll (2) or the like and has means for evaluating the measuring signals of the hardness measuring head (12). It is proposed to provide first and second means to monitor and, optionally, influence parameters of a material strip wound to form the roll, such as roll hardness, strip tension, uniformity of roll diameter along the roll width and the like, during winding. Said means can be used to hold at least one of the contact rolls (126, 127; 126', 126'', 127'') in position on the roll (2) with a first force and to cause at least one of the contact rolls (126, 127; 127', 127'') to penetrate with a second force deeper into the surface than with the first force.

摘要： The apparatus comprises an actuator (23) that can be pushed from an extended position to a depressed position. When doing so, the actuator (23) first releases an impact body (32) to impinge against the sample (2), and then a catcher (40, 42) to be moved to the released impact body (32) for bringing it back. The passage of the impact body (32) is detected by a reed switch (28), which wakes up the processing circuitry and switches the same between two modes of operation. In the first mode, the circuitry displays a device status, and in the second mode a measuring result.
