Test for Tire Quasi-Static Longitudinal Force versus Longitudinal Displacement and Quasi-Static Lateral Force versus Lateral Force

2018-09-25
WIP
J2718
This SAE Recommended Practice describes application of two closely related test procedures, which together determine the linear range longitudinal and lateral stiffnesses of a statically loaded non-rotating tire. The procedures apply to any tire so long as the equipment is properly sized to correctly conduct the measurements for the intended test tire. The data are suitable for use in determining parameters for road load models and for comparative evaluations of the measured properties in research and development. NOTE: Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular pavements. Within the context of this document, forces applied to the pavement are not considered.

Low Speed Enveloping Test with Perpendicular and Inclined Cleats

2018-09-25
WIP
J2731

This SAE Recommended Practice describes a test method for measuring the forces and moments generated at a spindle when a tire rolls over a rectangular obstacle, cleat, at very low speed. The cleat used in a particular test condition is configured with its crest either perpendicular, 90 degrees, to the path of the tire or optionally with its crest inclined at an angle to the path of the tire. The carriage to which the spindle is attached is rigidly constrained in position during each test condition so as to provide a good approximation to fixed loaded radius operation. The method discussed in this document provides cleat envelopment force and moment and tire angular position histories as functions of distance traveled. These histories are essentially free from variations due to tire non-uniformities. The method applies to any size tire so long as the equipment is properly scaled to conduct the measurements for the intended test tire.

Tire Quasi-Static Envelopment of Triangular/Step Cleats Test

2018-09-25
WIP
J2705

This SAE Recommended Practice describes a test method for determining properties of a non-rolling tire quasi-statically enveloping either a set of triangular cleats or a single step cleat. In the case of the triangular cleats the normal force and vertical deflection of the non-rolling tire are determined. In the case of the step cleats the normal force, longitudinal force, and vertical deflection of the non-rolling tire are determined. The method applies to any tire so long as the equipment is properly sized to correctly conduct the measurements for the intended test tire. The data are intended for use in determining parameters for road load models and for comparative evaluations of the measured properties in research and development.

NOTE: Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular pavements. Within the context of this document, forces applied to the pavement are not considered.

Hydrodynamic Drives Terminology

2018-09-25
WIP
J641
Since the torque converter and fluid coupling are commonly used components of automatic transmissions in industry, the SAE appointed a committee to standardize terminology, test procedure, data recording, design symbols, and so forth, in this field. The following committee recommendations will facilitate a clear understanding for engineering discussions, comparisons, and the preparation of technical papers. The recommended usages represent the predominant practice or the acceptable practice. Where agreement is not complete, alternates have been included for clarification. EXAMPLE: Two systems of blade angle designations are described. Consequently when a blade angle is specified, the system should be designated. This SAE Recommended Practice deals only with the physical parts and dimensions and does not attempt to standardize the design considerations, such as the actual fluid flow angle resulting from the physical blade shape.

Hydraulic Excavator Operator Controls

2018-09-25
WIP
J1177
This standard covers mobile hydraulic excavator controls and the specific arrangement and direction of motion for the primary controls. This standard applies to mobile hydraulic excavators as described in ISO 7135 - Earthmoving Machinery - Hydraulic excavators - Terminology and commercial specifications, and ISO 6165- Earthmoving Machinery - Basic Types - Vocabulary. Purpose This standard is intended as a guide for designing uniform two lever type operating controls for mobile hydraulic excavators, either wheel mounted or crawler mounted on independently reversible tracks.

Tire Normal Force/Deflection and Gross Footprint Dimension Test

2018-09-25
WIP
J2704
This SAE Recommended Practice describes a test method for determining the vertical force and deflection properties of a non-rolling tire and the associated contact patch length and width. The method applies to any tire so long as the equipment is properly scaled to conduct the measurements for the intended test tire. The data are suitable for use in determining parameters for road load models and for comparative evaluations of the measured properties in research and development.

Tests to Define Tire Size (Geometry), Mass, and Inertias

2018-09-25
WIP
J2717

This SAE Recommended Practice describes a trio of test methods which determine basic tire size (geometry), mass, and moments of inertia. The methods apply to any tire so long as the equipment is properly scaled to conduct the measurements for the intended test tire. The data are suitable for determining parameters for road load models and for comparative evaluations of the measured properties in research and development.

NOTE: Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular surfaces paved or unpaved. Within the context of this Recommended Practice, forces applied to the surface on which the tire is operating are not considered.

Contaminants for Testing Air Brake Components and Auxiliary Pneumatic Devices—Truck and Bus

2018-09-24
WIP
J2024
This SAE Information Report establishes a minimum level of uniform recipes for contaminants which may be used when durability testing pneumatic components to obtain additional information on how a device may perform under more true to-life operating conditions. This type of contamination testing, however, is not meant to replace the type of performance testing described in SAE J1409 and SAE J1410. Durability testing in the presence of contamination, however, will yield results more reflective of actual in-service field conditions and provide an additional evaluation of pneumatic devices. While the contaminant supply rate and other test criteria of the device being tested must be set by the device manufacturer or user, the items covered in this document will be: 1.1 Formula for contaminated oil to be used as a lubricant when testing air compressors. 1.2 Formula for a contaminant to be used when testing pneumatic system components other than air compressors. 1.3 Other contaminants.

Recommended Practices (RP) for Shipping Transport and Handling of Automotive-Type Battery System - Lithium Ion

2018-09-24
WIP
J2950
This RP aids in the identification, handling, and shipping of new and used un-installed lithium ion battery systems to and from specified locations. The generic term “battery system” shall be used to identify automotive-type and sized “traction” batteries when used as intended by the vehicle and battery system original equipment manufacturers (OEMs) for ground vehicles. It is the specific intent of this RP to identify, utilize and reference existing US and International hazardous materials (dangerous goods) transportation regulations, which are the only methodologies to be used to establish transportability of new battery systems. It is also the intent of this RP to provide recommendations regarding diagnostic testing to be used by service and shipping personnel for the purpose of determining a used battery system’s transportability. In support of the service and shipping personnel, the diagnostics process seeks to use standard tools of the trade and avoid laboratory type equipment.
