24、f gravity. is replaced by: The accelerometers shall be mounted at a single point (P) on the tunnel close to the vertical projection of vehicle centre of mass of the undeformed vehicle, but no further than 70 mm longitudinally and 40 mm laterally. Measurements made before the publication of the prese
25、nt standard, with accelerometers fixed to an installation close to the centre of mass are accepted. 6.2 Frequency requirements The following new requirement has been introduced: Since the data will be filtered by recursive (Butterworth) filters, more data should be collected than is specifically req
26、uired by the analysis. A recursive filter always produces “starting transients“ at the beginning and end of the data, and requires time to “settle down“. An additional 500 ms of data shall be collected at the beginning and end of the data; this extra data can then be discarded after filtering. 6.3 C

28、ent for the index PHD (Post impact Head Deceleration) has been removed. ASI and THIV are required. 8.1.1 Summary of the procedure to compute ASI In the procedure to compute ASI, averaging of the three components of the acceleration over a moving window of 50 ms has been replaced by filtering with a
29、four-pole phaseless Butterworth digital filter. 8.2 Vehicle cockpit deformation index (VCDI) 8.2.2 Location of the deformation The prefix ND has been added for impacts where there is no deformation of the vehicle cockpit. 8.2.3 Extent of the deformation “The sub-index 3 has been added for reductions

32、5 Introduction In order to improve and maintain highway safety, the design of safer roads requires, on certain sections of road and at particular locations, the installation of road restraint systems. These road systems are designated to redirect errant vehicles with a specified performance level an
33、d can provide guidance for pedestrians or other road users. This European Standard is a revision of EN 1317-1:1998. The standard identifies test methods and impact test acceptance criteria that the products for road restraint systems need to meet to demonstrate compliance with the requirements, give
34、n in EN 1317-5 and/or prEN 1317-6. The design specification, for road restraint systems entered in the test report, identify important functional site conditions in respect of the test installation. The performance range of the products for road restraint systems, designated in this standard, enable
35、s national and local authorities to recognize and specify the performance class to be deployed. Annexes A and B give informative explanation of the measurement of the severity index ASI and vehicle acceleration. BS EN 1317-1:2010EN 1317-1:2010 (E) 6 1 Scope This European Standard contains provisions
36、 for the measurement of performance of products for the road restraint systems, under impact and impact severity levels, and includes: Test site data; Definitions for road restraint systems; Vehicle specification (including loading requirements) for vehicles used in the impact tests; Instrumentation
37、 for the vehicles; Calculation procedures and methods of recording crash impact data including impact severity levels; VCDI. The modifications included in this standard are not a change of test criteria, in the sense of EN 1317-5:2007+A1:2008, ZA.3. 2 Normative references The following referenced do
