Rubber Vibration Isolator Testing Machine

Servo dynamic test bench for rubber mounts, used for static stiffness, dynamic stiffness, compression, shear and fatigue performance evaluation

Product Overview

This rubber vibration isolator testing machine adopts high-precision servo control system, designed for rubber mounts, rubber bushings and elastomeric vibration isolators widely used in automobiles, rail transit, construction and industrial equipment. It supports static compression test, static shear test, dynamic stiffness scanning, hysteresis curve test and cyclic fatigue test. The equipment can measure static stiffness, dynamic stiffness, loss factor, damping coefficient, creep and permanent deformation. It can apply combined compression-shear loading to simulate actual working conditions of rubber isolators. The built-in test software automatically collects force and displacement data, generates stiffness curves and hysteresis loops, calculates dynamic and static characteristic parameters, and exports test reports. It is widely used for new product development, formula optimization, incoming quality inspection and finished product verification of rubber vibration isolation components.

Applicable International Standards

The system is designed to comply with the following recognized testing standards:

• ASTM D945 — Standard Test Methods for Rubber Properties in Compression or Shear
