PREVENTING VIBRATION AND SHOCK FAILURES
by Prof. Dave Steinberg, P.E.
The purpose of this course is to show students proven, quick, short-cut methods to design, analyze and evaluate various sophisticated surface and through-hole mounted electronic systems for reliable operation in severe sine vibration, random vibration and shock environments without the use of a large computer.
OBJECTIVES
You will learn proven, quick methods for designing and evaluating the reliability of electronic equipment that can also be used as a sanity check for computer analysis, such as:
Finding the natural frequencies of many different beams, circuit boards and chassis.
Estimating transmissibility, Q, values for different beams, circuit boards and chassis.
Critical relationships between dynamic displacements, frequencies and accelerations.
How to find the minimum desired PCB natural frequency for sine, random and shock.
How to find component lead wire and solder joint forces, stresses and fatigue life.
How the component type, size, orientation and location on PCB affect the fatigue life.
Methods for improving reliability of commercial electronics in military environments.
Seven basic equations that can solve 85% of your vibration and shock problems.
Methods for quickly estimating fatigue life of many different types of components.
Quick and easy methods for finding the fatigue life in random vibration environments.
Why isolation systems are good for vibration and bad for shock, and visa versa.
