Guide for Reliability Analysis Using the Physics-of-Failure Process

2018-04-18
CURRENT
J2816_201804
The Physics-of-Failure (PoF) is a science-based approach to reliability that uses modeling and simulation to design-in reliability. This approach models the root causes of failures such as fatigue, fracture, wear, and corrosion. Computer-Aided Design (CAD) tools have been developed to address various loads, stresses, failure mechanisms and sites. PoF uses knowledge of basic failure processes to prevent failures through robust design and manufacturing practices, and aims to: Design-in reliability up front; Eliminate failures prior to testing; Increase fielded reliability; Promote rapid, cost effective deployment of Health and Usage Monitoring Systems (HUMS); Improve diagnostic and prognostic techniques and processes; and, Decrease operational and support costs. This guide provides a high level overview of the methodology, process and advantages to performing a PoF assessment.

Dynamic Cleat Test with Perpendicular and Inclined Cleats

2018-04-16
WIP
J2730
This SAE Recommended Practice describes a test method for measuring the forces and moments generated at a high frequency response spindle when a rolling tire impacts a cleat. The cleat is configured either with its crest perpendicular, 90°, 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 impact force and moment time histories 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. 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.

Handbook for Robustness Validation of Automotive Electrical/Electronic Modules

2018-04-16
WIP
J1211
This document addresses robustness of electrical/electronic modules for use in automotive applications. Where practical, methods of extrinsic reliability detection and prevention will also be addressed. This document primarily deals with electrical/electronic modules (EEMs), but can easily be adapted for use on mechatronics, sensors, actuators and switches. EEM qualification is the main scope of this document. Other procedures addressing random failures are specifically addressed in the CPI (Component Process Interaction) section 10. This document is to be used within the context of the Zero Defect concept for component manufacturing and product use. It is recommended that the robustness of semiconductor devices and other components used in the EEM be assured using SAE J1879 OCT2007, Handbook for Robustness Validation of Semiconductor Devices in Automotive Applications.

Battery Electric Vehicle Energy Consumption and Range Test Procedure

2018-04-16
WIP
J1634
This SAE Recommended Practice establishes uniform procedures for testing Battery Electric Vehicles (BEVs) which are capable of being operated on public and private roads. The procedure applies only to vehicles using batteries as their sole source of power. It is the intent of this document to provide standard tests which will allow for the determination of energy consumption and range for light-duty vehicles (LDVs) based on the Federal Emission Test Procedure (FTP) using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS), and provide a flexible testing methodology that is capable of accommodating additional test cycles as needed. Realistic alternatives should be allowed for new technology. Evaluations are based on the total vehicle system's performance and not on subsystems apart from the vehicle.

Measurement of Noise Emitted by Accelerating Road Vehicles

2018-04-06
WIP
J2805
This SAE Standard is equivalent to ISO 362-1:2015 and specifies an engineering method for measuring the noise emitted by road vehicles of categories M and N under typical urban traffic conditions. It excludes vehicles of category L1, L2, L3, L4, and L5. The specifications are intended to reproduce the level of noise generated by the principal noise sources during normal driving in urban traffic. The method is designed to meet the requirements of simplicity as far as they are consistent with reproducibility of results under the operating conditions of the vehicle. The test method requires an acoustical environment that is obtained only in an extensive open space.
