Designing Faultless Mechanical Products Based on Advanced Reliability Analysis

Serving as a foundational guide to the field, this book is an essential resource for professionals involved in the development of mechanical systems and related industries. It provides a comprehensive introduction to mechanical systems design and offers a detailed overview of the current advancements in mechanical systems design, as well as insights into future trends and applications.

Designing Faultless Mechanical Products Based on Advanced Reliability Analysis focuses on the mechanical system based on mechanism and parametric accelerated life testing (ALT). It describes basic reliability concepts, parametric ALT plans, failure mechanism and design, and reliability testing with acceleration factor and sample size equation. A generalized life-stress failure model with a new effort concept has been derived and recommended to calculate the acceleration factor of the mechanical system, which is discussed in the book and should help companies to improve product reliability and avoid recalls due to product/structure failures in the field. As the faulty designs of mechanical products are experimentally identified by this new reliability design method―parametric ALT―the mechanical/civil engineering system might improve in reliability by the increase in lifetime and the reduction in failure rate.

This book offers a thorough exploration of design concepts for professional engineers, college- and university-level lecturers, researchers, and design managers specializing in reliability. It is also beneficial for senior-level undergraduates and graduates studying mechanical, industrial, and civil engineering. Companies can utilize this resource to enhance product reliability and prevent recalls resulting from product or structural failures.

Seongwoo Woo earned BS and MS degrees in mechanical engineering and earned a PhD in mechanical engineering at Texas A&M University, USA. His major interests include energy systems, such as HVAC and heat transfer, the optimal design and control of refrigerators, the reliability design of mechanical components, and failure analysis of thermal components in the marketplace using nondestructive methods, such as scanning electron microscopy and X-rays. In particular, he has developed parametric accelerated life testing (ALT) as a new reliability methodology, which determines whether there is a design fault in a mechanical system that is subjected to repetitive stress. Using parametric ALT, engineers can find design faults before the product is launched and thus avoid failures.

From 1992 to 1997, Dr. Woo worked in the Agency for Defense Development in Chinhae, South Korea, where he was the researcher in charge of the development of naval weapons systems. From 2000 to 2010, he worked as a senior reliability engineer in the Side-by-Side Refrigerator Division, Digital Appliances, Samsung Electronics, where he focused on enhancing the lifetimes of refrigerators using parametric ALT. He is currently a professor in the Mechanical Department, Ethiopian Technical University, Addis Ababa.
