Overview

The rubber spring damper dynamic stiffness fatigue testing machine is a specialized testing equipment that uses electro-hydraulic servo/electric servo technology to apply controllable static preload+dynamic cyclic load/displacement to various isolation components (rubber, metal springs, air springs, dampers, etc.), accurately measuring their dynamic stiffness, damping ratio, loss factor, fatigue life, frequency response, phase difference and other key dynamic indicators; The integrated environmental chamber enables comprehensive testing under high and low temperature/humid and hot conditions, and is the core equipment for research and development, quality inspection, and certification.
