Sign Convention for Vehicle Crash Testing
J1733_201811
In order to compare test results obtained from different crash test facilities, standardized coordinate systems need to be defined for crash test dummies, vehicle structures, and laboratory fixtures. In addition, recorded polarities for various transducer outputs need to be defined relative to positive directions of the appropriate coordinate systems. This SAE Information Report describes the standardized sign convention and recorded output polarities for various transducers used in crash testing.
Rationale:
The committee performed the recommended Five-Year Review of this Information Report and determined that a number of changes were necessary. The major changes are outlined below.
Removed all references to BioSID.
Replaced Figures 1, 2, 3, 4, 5, 6, 7, 9, and 10 with updated artwork.
Added Angular Rate Sensor (ARS) and relevant ARS information and added ARS Figure 8.
Added Table 2 for THOR-50M dummy manipulations for recorded sensor polarities.
