Combined Cornering and Braking Test for Truck and Bus Tires

2017-11-29
CURRENT
J2675_201711
This SAE Recommended Practice describes a test method for determination of heavy truck (Class VI, VII, and VIII) tire force and moment properties under combined cornering and braking conditions. The properties are acquired as functions of slip angle, normal force, and slip ratio. Slip angle and normal force are changed incrementally using a sequence specified in this document. At each increment, the slip ratio is continually changed by application of a braking torque ramp. The data are suitable for use in vehicle dynamics modeling, comparative evaluations for research and development purposes, and manufacturing quality control. This document is intended to be a general guideline for testing on an ideal machine, and modifications to the protocols recommended within are expected depending on the requirements of each customer. Due care is necessary when modifying protocols to ensure that the integrity of the data is maintained.

Wireless Power Transfer for Light-Duty Plug-In/Electric Vehicles and Alignment Methodology

2017-11-27
CURRENT
J2954_201711
The SAE Recommended Practice J2954 establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety and testing for wireless charging of light duty electric and plug-in electric vehicles. The current version addresses unidirectional charging, from grid to vehicle, but bidirectional energy transfer may be evaluated for a future standard. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels 1, 2, and 3 with some variations. A standard for wireless power transfer (WPT) based on these charge levels will enable selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging, and ease of customer use. The specification supports home (private) charging and public wireless charging.

The CRABI dummy was developed to evaluate small child restraint systems in automotive crash environments, in all directions of impact, with or without air bag interaction Basic anthropometry for this test device was taken from the University of Michigan Transportation Research Institute Report 85-23. Weight distribution and scaling methods for the infant were approved by the Society of Automotive (SAE) Infant Dummy Task Group. The dummy weighs 17.2 pounds and has a 26.4 inches standing or 17.3 inches sitting height. The Hybrid Ill-like neck and lumbar spine are laterally notched to reduce lateral stiffness The shoulders have flesh support for durability and human-like performance in areas where seatbelt webbing may be placed. In addition, rubber elements are used in each joint to improve biofidelity and to give the CRABI infant-like range of motion. The CRABI Six-Month-Old design meets all the SAE Infant Dummy Task Group anthropometry, biomechanical and instrumentation requirements.

Rating of Winches

2017-11-03
CURRENT
J706_201711
This SAE Standard applies only to new winches which are primarily designed for intermittent pulls and lifts and whose configuration and condition are the same as when they were shipped by the manufacturer. They are not intended to be used in any manner for the movement of personnel. They may be driven by any power source recommended by the manufacturer and will be capable of being powered in either direction. They will be equipped with an automatic safety brake system to control a load when lowering under power and positively hold a load when power is not being delivered to the winch. A hydraulic flow control valve or similar device may be used in the brake system to control a load when lowering under power. A clutch to release the drum for “free-spooling” may be provided and will be designed not to disengage itself under load. A drag brake may be provided to control “free-spooling,” but will not be relied on to control or hold a load.
