Video Series Wrap-Up: Transmissibility
Concluding our 3 part video series on designing a vibration isolation solution, E-A-R™ “shock & vibe” engineers discuss the desired end result: reducing transmissibility in a system. (also, check out Part 1 and Part 2 if you have not already done so) Building upon the factors discussed in the first two parts, we finally arrive at transmissibility, or the ratio […]

Stiffness and Natural Frequency
Following up on Part 1 of our Designing a Vibration Isolation Solution video series, Part 2 covers the topics of stiffness (or “spring rate”) and natural frequency. As explained by Pete Masterson, Senior Applications Engineer for E-A-R™, spring rate is the amount of backforce exhibited by an isolator while under deflection. This is determined by both the corrected modulus […]

Modulus, Shape Factor, and Reading a Nomogram
When designing a vibration isolation solution, modulus and shape factor are among the first variables described by shock and vibration engineers. In Part 1 of a 3-part video series, E-A-R™ Application Engineer Chirag Patel walks us through how to determine these attributes. Inputs The first step in the process requires knowledge of two inputs: frequency and operating […]
