SCUD-B Typical Avionics Component The avionics shelves were made from hardwood. The wooden fibers may provide better damping then, say, an aluminum shelf. A possible disadvantage of wood is that the shelf would be unable to serve as an electrical or thermal ground plane. The… Read more
Here is a Matlab GUI script for calculating the natural frequency of a spring-mass system: sdof_fn.zip It can also be used to select total isolator stiffness for a given mass and intended natural frequency. It is version 1.1, so please let me know if there… Read more
I recently came across a vendor that offers an isolator design using the concept in the figure above. The system is also referred to as the standard-linear solid model (SLS) by Zener, and is used as a simplified model for structural damping. It is a… Read more
I have written some tutorials on avionics component isolation which may be downloaded at: avionics_iso.pdf six_dof_isolated.pdf * * * The Matlab GUI scripts are given in the GUI package at: Vibrationdata Matlab GUI Package The function is accessed via: Miscellaneous > Structural Dynamics > Spring-Mass… Read more
