17、SO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each 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, gov
18、ernmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC
19、 Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards 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 membe
20、r bodies casting a vote. ISO 13232-7 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 22, Motorcycles. This second edition cancels and replaces the first version (ISO 13232-7:1996), which has been technically revised. ISO 13232 consists of the following parts, under the

Its purpose is to define common research methods and a means for making an overall ev
24、aluation of the effect that devices which are fitted to motorcycles and intended for the crash protection of riders, have on injuries, when assessed over a range of impact conditions which are based on accident data. It is intended that all of the methods and recommendations contained in ISO 13232 s
25、hould be used in all basic feasibility research. However, researchers should also consider variations in the specified conditions (for example, rider size) when evaluating the overall feasibility of any protective device. In addition, researchers may wish to vary or extend elements of the methodolog
26、y in order to research issues which are of particular interest to them. In all such cases which go beyond the basic research, if reference is to be made to ISO 13232, a clear explanation of how the used procedures differ from the basic methodology should be provided. ISO 13232 was prepared by ISO/TC
27、 22/SC 22 at the request of the United Nations Economic Commission for Europe Group for Road Vehicle General Safety (UN/ECE/TRANS/SCI/WP29/GRSG), based on original working documents submitted by the International Motorcycle Manufacturers Association (IMMA), and comprising eight interrelated parts. T
28、his revision of ISO 13232 incorporates extensive technical amendments throughout all the parts, resulting from extensive experience with the standard and the development of improved research methods. In order to apply ISO 13232 properly, it is strongly recommended that all eight parts be used togeth
29、er, particularly if the results are to be published.

30、nt features of the simulation models; guidelines for definition and use of mathematical models for motorcycle impact simulations, which can be correlated against data for full-scale tests; a means for identifying possible additional impact conditions for full-scale testing; and a standardized tool,
31、of optional use, for risk/benefit analysis of rider crash protective devices fitted to motorcycles, based upon the population of impact conditions identified in ISO 13232-2. ISO 13232 specifies the minimum requirements for research into the feasibility of protective devices fitted to motorcycles, wh
32、ich are intended to protect the rider in the event of a collision. ISO 13232 is applicable to impact tests involving: two-wheeled motorcycles; the specified type of opposing vehicle; either a stationary and a moving vehicle or two moving vehicles; for any moving vehicle, a steady speed and straight-
33、line motion immediately prior to impact; one helmeted dummy in a normal seating position on an upright motorcycle; the measurement of the potential for specified types of injury by body region; evaluation of the results of paired impact tests (i.e. comparisons between motorcycles fitted and not fitt
34、ed with the proposed devices). ISO 13232 does not apply to testing for regulatory or legislative purposes.

The model shall consist of portions describing a motorcycle (MC) and the
44、 opposing vehicle (OV), as described in ISO 13232-6, the dummy, as described in ISO 13232-3, the dummy mounting position, joint tensions, and helmet, as described in ISO 13232-6, the protective device, if present, and the road surface. In the model, the following impact conditions shall be able to b
45、e varied, across the range of conditions described in Annex B of ISO 13232-2: MC impact speed; OV impact speed; MC contact point; OV contact point; relative heading angle. The model of the dummy should include the following bodies, at a minimum: a) helmeted head; b) neck; c) upper torso; d) lower to
46、rso; e) left and right: 1) upper legs; 2) lower legs; 3) feet; 4) upper arms; 5) lower arms; 6) hands. The model of the MC should include the following bodies at a minimum: front wheel; rear wheel; main frame; upper front fork assembly; lower front fork assembly. BS ISO 13232-7:2005 Licensed Copy: s

The upper leg, knee, and lower leg bodies shall be modelled so that the bone fracture/knee dislocation kinematics effects are simulated (e.g., resulting in reduced bend
48、ing moment in the leg at the appropriate location after fracture). If any of the bodies listed in Tables 1 and 2 can fracture, the masses of the bodies resulting from the fracture shall be modelled. For a given MC/protective device combination, the same model formulation shall be used for all impact
49、 configurations. The only differences between a model of a MC with a protective device and a model of a MC without a protective device shall be in those portions directly related to the protective device. 4.2 Parameters For each body listed in 4.1, the parameter values used should correspond to the actual measured: mass; centre of gravity location; momen
