Vibration Performance Evaluation of Operator Seats

2007-11-20
CURRENT
J1384_200711
This SAE Standard describes a procedure for the evaluation of operator seats which may be fitted to agricultural wheeled tractors per SAE J1150 and/or earthmoving machines per SAE J1057. This procedure evaluates only the vertical vibration performance and should not be considered a comprehensive seat evaluation procedure.

Occupant Restraint System for Off-Road Work Machines

WIP
J386
This SAE Standard establishes the minimum performance requirements for pelvic restraint systems (seat belts, anchorages, and the fastening elements of seat belts) necessary to restrain an operator or rider within a roll-over protective structure (ROPS) in the event of a machine roll-over, as defined in ISO 3471, ISO 8082-1, ISO 8082-2, ISO 12117-2, and ISO 13459, or tip-over protection structure (TOPS), in the event of a machine tip over as defined in ISO 12117.Note: Upper torso restraint requirements are defined in SAE J2292.

Measurement of Whole Body Vibration of the Seated Operator of Off-Highway Work Machines

2007-11-20
CURRENT
J1013_200711
This SAE Standard defines a method for the measurement of the whole body vibration to which the seated operator of off-highway self-propelled work machines is exposed while performing an actual or simulated operation. It applies to vibration transmitted to the operator through the seat. There are not equivalent ISO Standards. In the main body of this document, conditions are defined for measuring and recording whole body vibration of the seated operator of off-highway self-propelled work machines. The specification of instruments, analytic methods, and description of site and operating conditions allows the measurements to be made and reported with an acceptable precision. The procedure includes means of weighing the vibration level at different frequencies as specified in ISO2631. A standard format for reporting spectral data is recommended. The definitions, instruments, and analytic methods also apply to simulated tests for operator vibration as performed in laboratories.

Force-Deflection Measurements of Cushioned Components of Seats for Off-Road Work Machines

2008-04-11
HISTORICAL
J1051_200804
This SAE Standard provides a method to obtain consistent force-deflection data of finished (or unfinished, when specified) cushioned components of seats for off-road work machines as listed in SAE J1116. This data may be helpful in maintaining seat comfort characteristics and quality control. There is no intent to establish any acceptance criteria.

Development of a Frequency Weighted Portable Ride Meter

1987-01-30
CURRENT
J1225_198701
The purpose of this report is to record the activities and recommendations of the Ride Meter Task Force assigned by the chairman of the SAE Joint Seating Subcommittee to determine availability of instrumentation to measure operator ride on mobile equipment. The desired characteristics of the meter included relatively low cost, easy to operate, highly portable, and sufficiently rugged to withstand the vibration levels encountered on agricultural or construction machines. It is recognized that a ride meter type instrument with a single numerical output provides only approximate indication of ride vibration quality, but is useful for general field evaluation or overall ride comparisons. A narrow band analysis of the vibration frequency spectrum is recommended for more accurate and complete results.

Combination Pelvic/Upper Torso (Type 2) Operator Restraint Systems for Off-Road Work Machines

1997-08-01
HISTORICAL
J2292_199708
This SAE Information Report provides performance and test requirements for combination pelvic/upper torso operator restraint systems provided for off-road self-propelled work machines. This document applies to 3-point and 4-point operator restraint systems (Type 2 and Type 2A) for off-road, self-propelled work machines fitted with ROPS.
