Environmental Stress Testing and Reliability Engineering: A Comprehensive Approach
This training session delves into environmental stress testing methodologies and the fundamentals of reliability engineering. Participants will explore how to design and execute tests to simulate real-world operating conditions (i.e. vibration, temperature and humidity), accelerate life tests, and predict product failures. This course aims to equip engineers and quality professionals with essential knowledge and practical skills in understanding, planning, and executing various types of environmental tests to meet reliability targets.
Learning Objectives
- Understand the purpose of environmental stress testing and its role in reliability engineering.
- Differentiate between various test types, including temperature, humidity, altitude, and vibration testing, with emphasis on HALT and ALT methodologies.
- Learn about key measurement techniques and the impact of proper sensor selection and mounting on results.
- Gain insights into quantitative analysis using Repetitive Shock shakers and single degree of freedom (SDOF) models.
- Apply test acceleration models (Arrhenius, Inverse Power Law, Wohler, etc.) to predict product lifespan and failure rates.
- Define reliability concepts, including failure mechanisms vs. failure modes, operational profiles, and statistical life data analysis.
- Explore best practices for implementing environmental stress screening (ESS) to enhance quality controls in production.
