30 Years of HALT:  What we have learned

By Mike Silverman, Founder Ops A La Carte

Tutorial Abstract

About 30 years ago, some of the first papers on Strife and Tri-Axial Vibration Screening started being published.  A few years later, the terms HALT and HASS were coined.  By the early 90’s there were two different companies making equipment that could perform HALT.  By the late 90’s, there were many more.

Tutorial Outline

Over the past 30 years, there have been many advances in the methodologies of HALT, but many of the techniques have remained the same. 

I have been working in the area of HALT for 20 years and I would like to share with you what I have learned over these years.  And I would like to look ahead to the next 20 years to see what we can expect and what we may need from reliability testing tools.

Some of the areas we will cover in this tutorial are:

1)      History of HALT and HASS
2)      Links between HALT and Design for Reliability
3)      Links between HALT and Design for Robustness
4)      New advances in equipment
5)      New advances in HALT methodology
6)      New advances in HASS Development methodology
7)      What % of companies are doing HALT
8)      What % of companies are doing HASS
9)      New Techniques for HALT Calculation
             a.      MTBF Calculation
             b.      ROI Calculation
10)   What lies in the future for HALT

Reducing Life Cycle Costs through
Prognostics and Health Management (PHM)  

By Douglas L. Goodman, CEO Ridgetop Group, Inc.  

Tutorial Abstract

As companies seek to reduce the costs of deploying complex systems, many have found PHM methods to be a viable and cost-effective solution.  Prognostics, or predictive diagnostics, offers users the ability to avoid catastrophic failures, while reducing unscheduled maintenance costs.  This tutorial will cover the motivation for PHM, technologies involved, Return on Investment (ROI) calculations, and practical examples.

This tutorial will begin with definitions and taxonomy of PHM, and related terms such as Condition-based maintenance (CBM), and their relationship with the classical bath tub reliability curve and mean time between failure (MTBF).  The technologies associated with PHM will be discussed, where physical evidence of degradation (through signature extraction) can be leveraged to optimize the maintenance intervals on critical systems.  In harsh environments, systems will age faster while in mild environments, not as fast.  Thus, condition-based maintenance can guide more advanced and cost-saving measures for systems.

The role of Highly Accelerated Life Test (HALT), seeded fault analysis and their relationship with PHM will also be explored, with extensions in the development of accurate fault-to-failure progression models.

Application examples from aerospace, automotive, oil/gas industry and industrial networking will be provided.
