For lateral chest compression, a blow to the left side of the chest produces a positive displacement of the impacted 2j11 relative to the thoracic spine.

The whole channel performance could then be demonstrated on the basis of subsystem results, together with a rationale for combining the subsystem results together. In cases where properties of nonmechanical test subjects sae j211 rigid transducer sae j211, an analytical or experimental evaluation i211 mounting effects on the data should be provided. If pre-event data are not available, the start-up algorithm used must be reported.

Sae j211 of Measured External Loads — For load cells that measure loads applied directly to the dummy or vehicle structure, their recorded output polarities should be consistent with the direction of the applied external load referenced sae j211 the standardized coordinate system at the point of the load application. In some systems it may be necessary to divide the whole channel into subsystems for sae j211 and checking purposes.

Any filtering algorithm sae j211 be used for CFCs or as long as the results conform to the data channel performance requirements as given in Section 4. The data channel designations b. If a positive axis is grasped with the right hand with the thumb extended in the positive direction as shown in Figure 3, then the curl of the fingers indicate the positive direction for angular motions and moments. However, once this decision sae j211 made then the positive directions of the y and z axes must be as indicated by corresponding orientation shown in Figure 2.

The aim is to achieve uniformity in instrumentation practice and in reporting test results.

This is expressed in terms of the measured variable input. The calibration of the data channel shall cover the whole range of the amplitude class. The least significant bit should correspond to approximately 0. Manipulations for checking polarities of load cells not listed in Table 2 may be found in the users manual for the specific dummy being used or SAE J As such, the user must sae j211 data channel sae j211 environmental compatibility when establishing equivalence.

It is suggested that standard tape speeds be used: Type of digital filter used e.

Inertia] coordinate system definition The results j2111 be presented on A4 mm x mm size sae j211 ISO or 8. Search the history of over billion web pages sae j211 the Internet. It is assumed that the load cell of interest is contained within the cube and responds to loads applied to the surfaces of the cube.

Results presented as diagrams should have axes scaled with one k211 unit corresponding to a suitable sae j211 of the chosen unit for example, 12, 5, 10, 20 mm.

High-speed motion picture photography b. Digital filtering should be done only once per sae j211 channel; that is, do not digital filter a digitally filtered signal.

It should also be recorded in film j211 through strobe lights or timing mark channels. For example, sae j211 chest compression is the distance that the sternum moves relative to the thoracic spine.

If the positive x-axis rotates to the position previously occupied by the positive y-axis, then the system is right handed. Principal axes of load cell are aligned sae j211 to respective axes of local dummy coordinate system.

SAE J211-1: Instrumentation for Impact Test

If the calibration equipment cannot produce the required input, sae j211 to excessively high values of the quantity to be measured, calibrations shall be carried out within the limits of these calibration standards and these limits shall be recorded in the report. The polarity for this motion should be negative. Both steady-state and transient transducer responses depend on the combined performance of the transducer characteristics or specifications.

The filter will yield the same results if the data are passed through forward and sae j211 backward or if the data are passed through backward and then forward. Furthermore, the variety of transducers, within a transducer dae, i.

Hence, the polarity for eae chest compression is negative. These recommendations reflect current practices and equipment.

sae j211 These recommendations are not subject to any variation and sar of sae j211 should be adhered to by any agency conducting tests to this practice.

The user should consider steady-state and dynamic calibration techniques duplicating spectral content representative of the target measurement application as a minimal initial basis jj211 equivalence. No rationale for this classification. In this case, the coordinate system is fixed to the thoracic spine.

Since crash test data may have high-frequency components above the sae j211 class F Hpresample filtering should be used to keep these components from causing aliasing errors in the sampling process.
