12、09 ISO 8082-1:2009(E) iv ISO 2009 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. E
13、ach member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internati
14、onal Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standa
15、rds adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject
16、 of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8082-1 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 15, Machinery for forestry. This first edition of ISO 8082-1 cancels and
17、replaces ISO 8082:2003, of which it constitutes a minor revision. Whereas machines having a rotating platform with cab and boom on the platform remain excluded from the scope of this part of ISO 8082, the restructuring of the standard into discrete parts allows those machines to be addressed in ISO
18、8082-2. ISO 8082 consists of the following parts, under the general title Self-propelled machinery for forestry Laboratory tests and performance requirements for roll-over protective structures: Part 1: General machines Part 2: Machines having a rotating platform with a cab and boom on the platform

20、ible means of evaluating the forcedeflection characteristics of roll-over protective structures (ROPS) on self-propelled forestry machines under static loading, and prescribes performance requirements for a representative specimen under such loading. It is applicable to forwarders, skidders, feller-
21、bunchers, processors, harvesters and log loaders, as defined in ISO 6814. It is not applicable to machines having a rotating platform with a cab and boom on the platform, which are addressed by ISO 8082-2. NOTE The requirement levels and testing procedures of this part of ISO 8082 are the same as th
22、ose of ISO 3471 2 . 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

26、educe the possibility of a seat-belted operator being crushed should the machine roll over NOTE 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 t
27、hat are integral with the machine frame. 3.2 deflection-limiting volume DLV orthogonal approximation of a large, seated, male operator as defined in ISO 3411 wearing normal clothing and a protective helmet 3.3 falling-object protective structure FOPS system of structural members arranged in such a w
28、ay as to provide operators with reasonable protection from falling objects (e.g. trees, rocks) 3.4 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
29、 broken winch lines) 3.5 simulated ground plane SGP flat surface on which, after rolling, a forestry machine is assumed to come to rest 3.5.1 lateral simulated ground plane LSGP for a machine coming to rest on its side, the plane 15 away from the DLV about the horizontal axis within the plane establ

35、ed4 Static laboratory tests CAUTION Some of the tests specified in this part of ISO 8082 involve the use of processes which could lead to a hazardous situation. 4.1 Facilities Facilities for securing the ROPS/machine frame assembly to the bedplate, as specified in the following, and for applying lat
36、eral, 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 to which the operators seat is normally secured, and shall remain there during the entire formal test period. For mac
37、hines 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 with instruments for measuring the force applied to the protective structure and the deflection (deformation) of the str
38、ucture. The instrument accuracy shall be in accordance with Table 2. Table 2 Instrument accuracy requirements Measurement Accuracy aDeflection of ROPS 5 % of maximum deflection measured Force applied to ROPS 5 % of maximum force measured aThe percentages are nominal ratings of the accuracy of the in
39、strumentation 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 attached to the machine frame or body as it would be on an operating machine. A complete machine is not required for the
40、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 elements shall be removed so that they neither contribute to, nor detract from, the structural evaluation. 4.3.1.2 ROPS/
41、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 during testing. During lateral loading, the ROPS/machine-frame assembly shall not receive any support from the bedpla
42、te, 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. For articulated machines, if both frames are used in the evaluation, the hinge shall be locked so that the frames are
43、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). BS ISO 8082-1:2009 ISO 8082-1:2009(E) ISO 2009 All rights reserved 54.3.1.3 Elimination of energy absorbers The assembly shall be secured or
44、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 include suspension or flexible shock absorbers, which shall not be altered.
45、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 attachment to bedplate 4.4 Test procedures 4.4.1 General The test procedures sh
46、all 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 out during or between the lateral, vertical and longitudinal loading. NOTE
47、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 longitudinal members of the ROPS. 4.4.2.2 For a ROPS having more than two pos
48、ts, 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 curved structural members, the load-distribution device may be attached to the
49、 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. The 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 proje
