Summary

 
Object and purpose of research.This paper studies ESA-100-type rubber-metal vibration isolator. The purpose of this work is to study the effect of static load upon dynamic parameters of this vibration isolator
Subject matter and methodsVibration isolators were tested at JSC PO Sevmash servohydraulic test rig being one of dynamic test facilities for vibration isolators. The method of the study was mechanical impedance measurement on vibration isolators under static loads
Main results.This study yielded an empirical formula for dynamic stiffness increase coefficient of ESA-100 vibration isolator versus the increase coefficient of static load.
Conclusion.The empirical formula yielded by this study makes it possible to calculate actual stiffness of ESA-100 vibration isolator when actual static load is several times higher than the nominal one
