Abstract: Active phased array radar (APAR) is equipped with a transmitting/receiving (T/R) component for each radiator, and the T/R component is interconnected with the PCB through solder balls. With ...

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: Aiming at the structural strength of the power battery pack of new energy vehicles under random vibration conditions, a finite element simulation method is used for analysis and optimization ...
