24、bols For the purposes of this document, the following terms, definitions and symbols (see Table 1) apply. 3.1 roll-over protective structure ROPS system of structural members whose primary purpose is to reduce the possibility of a seat-belted operator being crushed should the machine roll over NOTE

25、These structural members include any subframe, bracket, mounting, socket, bolt, pin, suspension or flexible shock absorber used to secure the system to the machine frame, but exclude mounting provisions that are integral with the machine frame. 3.2 deflection-limiting volume DLV orthogonal approxima

27、.4 operator protective structure OPS system of structural members arranged in such a way as to minimize the possibility of operator injury from penetrating objects (such as whipping saplings, branches and broken winch lines) 3.5 simulated ground plane SGP flat surface on which, after rolling, a fore

NOTE The LSGP is e

29、stablished on an unloaded ROPS and moves with the member to which load is applied while maintaining its 15 angle with respect to the vertical. 3.5.2 vertical simulated ground plane VSGP rollbar ROPS for a machine coming to rest in an upside-down position, the plane defined by the top cross-member of

30、 the ROPS and that front (or rear) part of the machine likely to come in contact with flat ground at the same time as the ROPS and capable of supporting the upside-down machine NOTE The VSGP moves with the deformed ROPS.

34、ies for securing the ROPS/machine frame assembly to the bedplate, as specified in the following, and for applying lateral, longitudinal and vertical loads, shall be provided. The DLV and its location shall be in accordance with ISO 3164. The DLV shall be fixed firmly to the same part of the machine

35、to which the operators seat is normally secured, and shall remain there during the entire formal test period. For machines with a reversible operators position, the DLV is to be considered as the combined clearance zones for the two positions. 4.2 Instruments The test apparatus shall be equipped wit

36、h instruments for measuring the force applied to the protective structure and the deflection (deformation) of the structure. The instrument accuracy shall be in accordance with Table 2. Table 2 Instrument accuracy requirements Measurement Accuracy aDeflection of ROPS 5 % of maximum deflection measur

37、ed Force applied to ROPS 5 % of maximum force measured aThe percentages are nominal ratings of the accuracy of the instrumentation and shall not be taken to indicate that a compensating overtest is required. 4.3 Apparatus 4.3.1 General 4.3.1.1 Assembly of ROPS to machine frame The ROPS shall be atta

38、ched to the machine frame or body as it would be on an operating machine. A complete machine is not required for the evaluation; however, the machine frame or body and ROPS mounting shall represent an operating installation. All normally detachable windows, panels, doors and other non-structural ele

39、ments shall be removed so that they neither contribute to, nor detract from, the structural evaluation. 4.3.1.2 ROPS/machine attachment to bedplate The ROPS/machine-frame assembly shall be secured to the bedplate so that the members connecting the assembly and bedplate experience minimal deflection

40、during testing. During lateral loading, the ROPS/machine-frame assembly shall not receive any support from the bedplate, other than that due to the initial attachment. Connections to the bedplate shall be directly from the machine frame at or near the front-axle support and the rear drive support. F

41、or articulated machines, if both frames are used in the evaluation, the hinge shall be locked so that the frames are in a straight line. If the frame on which the ROPS is mounted is used alone, the connections shall be at or near the extreme ends of the frame (see Figure 2). DIN ISO 8082-1:2016-06 9

42、 4.3.1.3 Elimination of energy absorbers The assembly shall be secured or modified or both so that any machine element that might be considered as suspension (rubber, gas, gas-oil or mechanical spring) shall be effectively eliminated as an energy absorber. However, the ROPS-structural members may in

43、clude suspension or flexible shock absorbers, which shall not be altered. 4.3.2 Vertical loading For vertical loading, there is no limitation on securing or supporting the ROPS/machine-frame assembly, except that no repair or straightening of the assembly shall be carried out. Figure 2 Machine attac

44、hment to bedplate 4.4 Test procedures 4.4.1 General The test procedures shall consist of the operations specified in 4.4.2 (lateral loading), 4.4.3 (vertical loading) and 4.4.4 (longitudinal loading), carried out in that order. No repair or straightening of any ROPS/machine member shall be carried o

45、ut during or between the lateral, vertical and longitudinal loading. NOTE The figures referred to are illustrative and not intended to restrict the design of loading devices. 4.4.2 Lateral loading 4.4.2.1 The forcedeflection characteristics shall be determined by lateral loading of the top major lon

46、gitudinal members of the ROPS. 4.4.2.2 For a ROPS having more than two posts, the lateral loading shall be applied through a load-distribution device having a length not greater than 80 % of the horizontal distance, L, between the front and rear posts of the ROPS (see Figure 3). In the case of curve

47、d structural members, the load-distribution device may be attached to the ROPS but shall not have any affect on the strength of the ROPS. 4.4.2.3 For all one- or two-post ROPS, initial loading shall be dictated by the length, L, and the vertical projections of the front and rear planes of the DLV. T

48、he load application point may not be within L/3 of the ROPS structure. Should the L/3 point be between the vertical projection of the DLV and the ROPS structure, the load application point shall be moved away from the structure until it enters the vertical projection of the DLV (see Figure 4). DIN I

49、SO 8082-1:2016-06 10 4.4.2.4 The initial direction of loading shall be horizontal and perpendicular to a vertical plane through the machines longitudinal centreline. As loading continues, the ROPS/machine-frame deformations can cause the direction of loading to change: this is permissible. 4.4.2.5 If the operators seat is off the machines longitudinal centreline, the loading shall be against the outermost side nearest the seat. For on-centreline seats, if mounting of
