The ability to successfully predict industrial product performance during service life provides benefits for producers and users. This book addresses methods to improve product quality, reliability, and durability during the product life cycle, along with methods to avoid costs that can negatively impact profitability plans. The methods presented can be applied to reducing risk in the research and design processes and integration with manufacturing methods to successfully predict product performance. This approach incorporates components that are based on simulations in the laboratory. The results are combined with in-field testing to determine degradation parameters. These approaches result in improvements to product quality, performance, safety, profitability, and customer satisfaction.

Owing to the enhanced requirement of brake free noise these days, more damping kits should be installed in the braking system. Success of doing this properly causes softness in the brake system which results in the loosened stroke feeling of brake pedal, the increased compressibility by durability. A study for detailed factors to aggravate brake feeling was done as a solution to prevent these from happening. In this paper, we present our work based on experiments to measure compressibility of shims by the influence of variations in different parameters, for example, of adhesive shims (bonding spec., steel and rubber thickness), piston’s shapes (different contact areas to the shims), and the numbers of durability. We installed the brake feeling measurement system extended from brake pedal to caliper. Experimental parameters were compared with brake feelings in vehicle using it. The optimization for brake feeling was determined by design for six sigma (DFSS).

ARP9005A
General: This document contains recommended practices for the effective control of non-deliverable software. It addresses practices for control during the development, production, release maintenance, and retirement of non-deliverable software, as well as for software procured from outside manufacturers and incorporated in the production, evaluation, test, acceptance or calibration of processes. For the purposes of this document, the terms software and non-deliverable software are considered synonymous. Application: The guidelines in this ARP apply to non-deliverable software that: - directly relates to design, manufacture, inspection, test or calibration of a deliverable product, and - directly affects the configuration, conformity or quality of a deliverable product.

Abstract Efficiency and durability are key areas of research and development in modern racing drivetrains. Stringent regulations necessitate the need for components capable of operating under highly loaded conditions whilst being efficient and reliable. Downsizing, increasing the power-to-weight ratio and modification of gear teeth geometry to reduce friction are some of the actions undertaken to achieve these objectives. These approaches can however result in reduced structural integrity and component durability. Achieving a balance between system reliability and optimal efficiency requires detailed integrated multidisciplinary analyses, with the consideration of system dynamics, contact mechanics/tribology and stress analysis/structural integrity. This paper presents an analytical model to predict quasi-static contact power losses in lubricated spur gear sets operating under the Elastohydrodynamic regime of lubrication.

This document proivdes the guidelines for the utilization of Cpk as a monitor of process performance. This document: -defines the process capability index (Cpk), -outlines some general methods for estimating Cpk, -describes acceptable methods of reporting Cpk, -discusses the advantages, disadvantages, and requirements for some potential applications of Cpk, -addresses the use of similar methods of assessing quality improvement, and -provides some perspective on the value of Cpk and similar techniques. Application of the guidelines in this document should allow businesses to use Cpk or similar techniques to effectively monitor one aspect of quality improvement and to promote strong customer/supplier relationships.

This paper originated with a software quality panel workshop at the EIA Computer Resources Workshop. The panel group initially focused on requirements for nondeliverable software. It was felt that the requirements for deliverable software were well covered by Department of Defense standards but non-deliverable software issues were not adequately covered. After much discussion, including attempts to define nondeliverable by examples of software types, a surprising unanimous conclusion was reached by the participants. That is: the states of "deliverable" and "non-deliverable" had no bearing on the quality of the software, and thereby also had no bearing on the quality assurance requirements that should be applied for that software. Rather, the only rational application of quality assurance was primarily dependent on the impact that the software had, or could have, on the end product (¡.e. the ultimate mission).
