Residual Aligning Moment Test

2019-07-11
WIP
J1988
This Recommended Practice describes the determination of tire pull force properties for an uninclined tire (SAE J670e) on a laboratory flat surface tire force and moment machine. It is suitable for accurately determining pull forces and residual aligning moments for passenger and light-truck tires. These properties are important determinants of vehicle trim. They describe steady-state, free-rolling pull effects ascribable to tires. The test method described in this document is suitable for comparative evaluation of tires for research and development purposes. The method is also suitable for modeling when followed carefully.

Force and Moment Test Method

2019-07-11
WIP
J1987
This SAE Recommended Practice describes the determination of passenger car and light truck tire force and moment properties on a belt-type flat surface test machine. It is suitable for accurately determining five tire forces and moments in steady-state under free-rolling conditions as a function of slip angle and normal force which are incrementally changed in a given sequence. Heavy-duty tires are not considered in this document, because the measuring system would have force and moment ranges too large to meet sensitivity requirements for passenger and light truck tire force and moment measurements. A standard for heavy-duty truck tires would have many of the same features as this document, but the measuring system, would have to be extensively altered. Inclination angle combined with slip angle, pull forces, and any combination with spindle torque are not considered in this document. Standards needed for these topics will be considered separately.

ARP6461A
This document is applicable to civil aerospace airframe structural applications where stakeholders are seeking guidance on the definition, development and certification of Structural Health Monitoring (SHM) technologies for aircraft health management applications. For the purpose of this document, SHM is defined as “the process of acquiring and analyzing data from on-board sensors to evaluate the health of a structure.” The suite of on-board sensors could include any presently installed aircraft sensors as well as new sensors to be defined in the future.

Pneumatic Tire/Wheel/Runflat Assembly Qualifications for Military Tactical Wheeled Vehicles

2019-03-22
WIP
J2014
This SAE Standard applies to all combinations of pneumatic tires, wheels, or runflat devices for military tactical wheeled vehicles only as defined in SAE J2013. This applies to original equipment and new replacement tires, retread tires, wheels or runflat devices. This document describes tests and test methodology, which will be used to evaluate and measure tire/wheel/runflat system and changes in vehicle performance. All of the tests included in this document are not required for each tire/wheel/runflat assembly. The Government Tire Engineering Office and Program Office for the vehicle system have the responsibility for the selection of a specific test(s) to be used. The selected test(s) should be limited to that required to evaluate the tire/wheel/runflat system and changes in vehicle performance. Selected requirements of this specification shall be used as the basis for procurement of a tire, wheel and/or runflat device for military tactical wheeled vehicles.

Configuration Management Standard

2019-02-07
CURRENT
EIA649C
This standard defines five CM functions and their underlying principles. The functions are detailed in Section 5. The principles, highlighted in text boxes, are designed to individually identify the essence of the related CM function and can be used to collectively create a checklist of “best practice” criteria to evaluate a CM program. The CM principles defined in this standard apply equally to internally focused enterprise information, processes, and supporting systems (i.e., Enterprise CM - policy driven, supporting the internal goals needed to achieve an efficient, effective and lean enterprise), as well as to the working relationships supported by the enterprise (i.e., Acquirer/Supplier CM - contracted relationship to support external trusted interaction with suppliers).

Earned Value Management Systems

2019-01-08
CURRENT
EIA748D
An Earned Value Management System (EVMS) for integrated program management will effectively integrate the work scope of a program with the schedule and cost elements for optimum program planning and control. The primary purpose of the system is to support integrated program management. The system is owned by the organization and is governed by the organization’s policies and procedures. The principles of an EVMS are: Plan all work scope for the program to completion. Break down the program work scope into finite pieces that are assigned to a responsible person or organization for control of technical, schedule and cost objectives. Integrate program work scope, schedule, and cost objectives into a performance measurement baseline plan against which accomplishments are measured. Control changes to the baseline. Use actual costs incurred and recorded in accomplishing the work performed. Objectively assess accomplishments at the work performance level.

AIR6037A
This report provides current practice measurement methods for quantifying nonvolatile particle matter at the exit plane of aircraft gas turbine engines. This document contains detailed information for many instruments and techniques, described in AIR5892A, that have been applied in aircraft engine field tests since AIR5892A was first issued in April 2003. There are four sections, identified as Technical Appendices (TA), presenting measurement techniques, sampling, and quantification of nonvolatile particles. The sections are written in the format of Aerospace Recommended Practice (ARP) documents and intended to progress to recommended practices upon overcoming existing technical challenges.

Tire Quasi-Static Envelopment of Triangular/Step Cleats Test

2018-11-20
CURRENT
J2705_201811
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.1 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.

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.

Low Speed Enveloping Test with Perpendicular and Inclined Cleats

2018-11-20
CURRENT
J2731_201811
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.
