19、m test load Fmaxmaximum value of load applied to the beam flange during testing according to its quality class 4 Quality classification Beam flanges are classified according to four quality classes. The designation of the quality classes is Q1, Q2, Q3 or Q4. Depending on the quality class, the beam
20、flanges are loaded with different ultimate loads. These limit values are given in Clause 6. For examples of application by quality class, see Annex A.

21、ectional beams 5 DIN ISO 8116-4:2009-08 5 Test methods 5.1 Principle The beam flange is subjected to a test load and the resulting deformation is measured. For weavers beams, the test load is applied to the flange via a beam barrel. For warpers beams and sectional beams, the load is applied to the b
22、eam flange via a pressure plate. A pressure ring with a defined inner diameter is used as an anvil. The permanent deformation and the plastic deformation of the flange shall not exceed the defined limit values when the maximum load is applied. 5.2 Apparatus 5.2.1 Press device, with indications for t
23、he application of the test load. 5.2.2 Three dial gauges, for determination of deformation of the flange with an accuracy of 0,01 mm. 5.2.3 Measurement device, for joint installation of the three dial gauges on the bearing device, in an angle of 120 each. 5.2.4 Steel pressure ring. 5.2.5 Beam barrel
24、, for load application (for weavers beams). 5.2.6 Pressure plate, for load application (for warpers beams and sectional beams). 5.3 Testing configuration For measurement of flange deformation, three dial gauges are installed on the bearing device by means of the measurement device. These are used to
25、 measure the relative path between the outer diameter of the beam barrel d2and the circle diameter d1 20 mm. The dial gauges are staggered by 120. The testing configuration for weavers beams is given in Figure 1. The testing configurations for warpers beams are given in Figure 2 and Figure 3. The te

33、stalled as described in 5.3. The beam flange, the pressure ring and the pressure plate, if required, are aligned centrally below the press loading pad. Stepwise loading of the flange shall occur in steps to be chosen usefully. The load applied and the deformation are determined at the test area for
34、each loading step. The value of the total deformation is calculated from the average of the three measurement values. After each load step, unloading of the flange is optional. After unloading, the values indicated are read with the dial gauge. The values for the plastic deformation are calculated f
35、rom the average of the three measurement values. Then loading is applied with the next higher load value. This procedure is repeated until the defined maximum test load of the corresponding quality class as given in Equation (2) and Table 1 is reached. The beam flange corresponds to the quality clas
36、s if the value measured for the total deformation and the value measured for the plastic deformation are below the values obtained when using Equation (3) and Equation (4). 9 DIN ISO 8116-4:2009-08 Once the given maximum load has been achieved, the plastic deformation shall be measured after unloadi
37、ng. Subsequently, the dial gauges are set to “zero”. The maximum test load shall again be applied. After unloading, only an insignificantly low residual deformation value shall be read. 6 Pressure ring diameter, maximum test load and limit values of deformation The diameter of the pressure ring, max
38、imum test load and limit values of deformation shall be calculated using Equations (1), (2) or (3) for any flange geometry: for weavers beams in accordance with ISO 8116-3, the values are given in Table 2; for warpers beams in accordance with ISO 8116-2, the values are given in Table 3; for sectiona
39、l beams in accordance with ISO 8116-5, the values are given in Table 4. 6.1 Pressure ring diameter The diameter of the pressure ring is calculated, depending on the inner and outer diameter of the beam flange, using Equation (1): 3312i221223ddDdd=(1) where Diis the inner diameter of the pressure rin
40、g, in millimetres; d1is the outer diameter of the beam flange, in millimetres; d2is the outer diameter of the beam barrel, in millimetres. The tolerance for the diameter of the pressure ring, Di, may not exceed 1 mm. NOTE Equation (1) corresponds to the centre of the diameter of a circular ring segm
41、ent on the condition that the angle of the circular ring segment reaches zero. In practice, the actual load on the beam flange is different, depending on the winding. 6.2 Maximum test load Depending on the quality class, the maximum test load is calculated from the maximum test load given in Table 1
42、 multiplied by the maximum winding area of the beam flange, using Equation (2). max max iF Ap= (2) where Fmaxis the maximum test load, in kilonewtons; Amaxis the maximum winding area of the beam flange, in square millimetres; 22max 1 2()4A dd= piis the maximum test load, in megapascals. 10 DIN ISO 8

44、00ddf= (3) where ftot-limis the admissible total flange deformation, in millimetres; d1is the outer diameter of the beam flange, in millimetres; d2is the outer diameter of the beam barrel, in millimetres. The limit value of the plastic deformation at maximum test load amounts to a quarter of the lim
45、it value of total deformation in the case of initial loading of the beam flange. If the maximum test load is again applied to the beam flange, as shown in Equation (4), the proportion of plastic deformation shall be insignificantly low. tot lim 12plast lim()4 1000f ddf= (4) where fplast-limis the ad
