4、National Standard J2418 ISSUED JAN98 Issued1998-01 Occupant Restraint System Evaluation Frontal Impact Component-Level Heavy Trucks 1.ScopeThis SAE Recommended Practice describes the test procedures for conducting frontal impact restraint component tests for heavy truck applications. Its purpose is
5、to establish recommended test procedures that will standardize restraint system testing for heavy trucks. Descriptions of the test set-up, test instrumentation, photographic/video coverage, and the test fixtures are included. 2.References 2.1Applicable PublicationsThe following publications form a p

8、 title 49, Part 571.208. 3.Test DummiesFor the dynamic tests described in the following sections, restraint systems should be evaluated with the aid of a test dummy. The test dummy should be of a type that will closely represent the size, weight, and articulation characteristics of a 50th percentile
9、 male in a seated position. An example of such a test dummy is the Hybrid-III 50th percentile male anthropomorphic test device. The physical characteristics of this dummy are described in SAEs Engineering Aid 23, “Users Manual for the 50th Percentile Hybrid III Test Dummy,“ June 1985. SAE J2418 Issu
10、ed JAN98 -2- Applicable measurement capabilities of the Hybrid-III 50th percentile male test dummy are as follows: Head triaxial acceleration (3 channels) Upper neck forces and moments (6 channels) Lower neck forces and moments (6 channels) Chest triaxial acceleration (3 channels) Chest deflection (
11、1 channel) Lumbar forces and moments (6 channels) Pelvic triaxial accelerations (3 channels) Test dummies of other sizes (i.e., 95th-percentile male, 5th-percentile female, etc.) may also be used to evaluate restraint component performance for various occupant sizes. 4.Dynamic Sled TestsFor the rest
12、raint component tests, only the subject seat and associated restraint system hardware are installed on the test sled. No other interior cab component need be installed. Proper restraint anchorage geometry, relative to the seat, should be maintained. Tethers should be set according to the manufacture
