Abstract: Random vibration caused by the base excitation is a very common environment to many products, especially to those mounted on a vehicle. Two fundamental vibration models, ...

Many readers probably think “black magic” describes the math involved in finding the dynamic response of a structure from random excitation. When can you be sure you have jumped through all the ...

NOTE: Click on images or equations to make them larger. Last month’s column discussed the basics of simulating resonant or natural vibration frequencies as an introduction to performing advanced ...

Abstract: This paper presents a High Cycle Fatigue (HCF) analysis of a SAC305 electronic assembly subjected to random vibration loading. Sinusoidal durability tests are first conducted at various ...

High-power laser diodes (HPLDs) are increasingly used in space applications, yet solder layer (SL) reliability critically limits their performance and lifespan. This study employs finite element ...
