11、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. Each member body interested in a subject for which a technical committee

12、 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 International Electrotechnical Commission (IEC) on all matters of electrotechnic

13、al 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 Standards adopted by the technical committees are circulated to the member bo

14、dies 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 of patent rights. ISO shall not be held responsible for identifying an

15、y or all such patent rights. ISO 11096 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 10, Impact test procedures. This second edition cancels and replaces the first edition (ISO 11096:2002), which has been technically revised. BS ISO 11096:2011ISO 11096:2011(E) ISO 201

16、1 All rights reserved vIntroduction The intent of this International Standard is to help standardize the pedestrian leg impactor test method that will allow a test organization to use the results from pedestrian impact tests conducted by other test organizations. The method is based on the simulated

17、 impact of a motor vehicle on an adult pedestrian. It is anticipated that biomechanical data for children will later be studied in order to determine the potential for child pedestrian protection. Research suggests that safety improvements in vehicles derived from such pedestrian impact tests would

18、also be beneficial to motorcyclists and bicyclists (see Annex D).

19、cifies a test method for simulating the lateral impact between the front of a passenger vehicle or light truck vehicle derived from passenger cars (as defined in ISO 3833) and an adult pedestrian. The test method addresses the reduction of pedestrian thigh, leg and knee injuries. It is not applicabl

20、e to testing for, or the evaluation of, injuries to other pedestrian body regions, nor does it directly cover the potential risk of injury to children or human soft tissue. It is not applicable to vehicles with deployable devices designed for activation in the event of impact with a pedestrian. 2 No

They and the other ph

31、ysical properties of the legform impactor shall be as follows. a) Leg length between the bottom and the knee joint centre: (493 5) mm. b) Thigh length between the knee joint centre and the top: (428 5) mm. c) Centre of gravity of leg from the knee joint centre: (233 10 ) mm.

If used, the thigh with adaptor shall still comply with the thigh requirement of

34、mass, centre of gravity and moment of inertia. k) There shall be a simulation of flesh or skin on the outer surface of the legform impactor. This material shall be human-like. 5.1.2 Shape of legform impactor The shape of the legform impactor shall be cylindrical. The outer diameter of the thigh and

35、that of the leg shall be the same: (120 10) mm, including a “flesh” thickness of (30 5) mm. 5.1.3 Biofidelic performance characteristics The legform impactor shall meet the biofidelic performance targets given in Annex A. 5.1.4 Certification of legform impactor The legform impactor shall meet the ce

36、rtification requirements given in Annex B. 5.1.5 Calibration of legform impactor deformable elements Once the structural design of the deformable knee element meeting the requirements specified in 5.1.3 and 5.1.4 is completed, the designer of the legform impactor shall provide a calibration test pro

37、cedure in which each batch of deformable knee elements shall be checked to see if their performance is acceptable. Such a calibration test procedure may be applied statically if this test proves that the characteristics of the batch are similar to those of the original design. The response adopted a

38、s a requirement for a calibration test should allow for a reasonable variation in production. 5.2 Propulsion of legform impactor The legform impactor shall be propelled in free flight into the stationary test vehicle. The method of legform impactor propulsion is at the discretion of the test office;

39、 however, the knee joint should be supported during legform impactor acceleration. The trajectory of the legform impactor shall be parallel to the ground within 6 at impact with the vehicle, and its angular velocity at this time shall be less than 50/s. Because of the effect of gravity and depending

40、 on the length of free flight, this may require that the trajectory of the legform impactor at the time of its release from the propulsion system be at an angle above horizontal. There shall be no contact between the legform impactor and the propulsion system during impact with the vehicle. 5.3 Legf

41、orm impactor setting 5.3.1 The legform impactor shall be straight, and vertical in pitch and roll at the time of impact (see Figure 2). The tolerances for pitch, roll and yaw shall be 5.

42、l be at or within 10 mm of the level of the ground reference plane (GRP) at impact with the vehicle. The legform impactor shall not come into contact with the ground during impact (see Figure 2). 5.4 Test temperature The legform impactor shall have a temperature of (20 5) C at the time of impact. Ho

43、wever, a narrower range may be required to keep the performance of the legform impactor within the specified limits. 6 Preparation of test vehicle 6.1 Either a complete vehicle or cut-body shall be used for the test. All parts of the vehicle structure and components that could be involved in a pedes

44、trian leg impact shall be in place. 6.2 The ground clearance of the test vehicle or cut-body shall be set to simulate that of an actual vehicle with tyres inflated to the nominal tyre pressure specified by the manufacturer. Spacers may be placed under the tyres in order to bring the vehicle to a hei

45、ght that will allow the free flight of the legform impactor. NOTE Testing with or without numberplate (licence plate) is at the discretion of the test laboratory or government body. The material and size of the plate may be standardized during a given test programme when testing a vehicle with plate

46、. 6.3 For tests of a complete vehicle, the suspension shall be set to the normal ride height attained at the test impact velocity (specified in the relevant laws and regulations or by the concerned government agencies) and shall include the complete vehicle kerb mass (ISO-M06) in accordance with ISO

47、 1176, with one adult male 50th percentile dummy or an equivalent mass placed on the drivers seat, and with one adult male 50th percentile dummy or an equivalent mass placed on the passengers seat. 6.4 For tests using a cut-body, the height of the body above the ground reference plane shall be the s

48、ame as that of the complete vehicle loaded in accordance with 6.3. 6.5 The parking brake shall be applied, or the cut-body shall be securely mounted. 6.6 Sufficient time shall be allowed for the temperature (see 7.1) of all vehicle components to stabilize before testing. 7 Test conditions 7.1 Atmosp
