The Rubber Bushing Dynamic and Static Stiffness Test Bench is a specialized testing system designed to evaluate the static stiffness, dynamic stiffness, and fatigue performance of rubber bushings and other rubber vibration-isolation components.The equipment adopts an electro-hydraulic servo control system with computer measurement and control technology. It can simulate the actual working conditions of rubber components and perform static tensile, static compression, dynamic stiffness, and long-term fatigue tests to evaluate the mechanical properties, durability, and service reliability of rubber components.
The Rubber Bushing Dynamic and Static Stiffness Test Bench is mainly used for performance testing of:
Automotive suspension rubber bushings
Engine mounts and rubber vibration isolators
Chassis rubber components
Rubber joints and elastic components
Other rubber and elastomer products
Typical testing functions include:
Static tensile stiffness testing
Static compression stiffness testing
Dynamic stiffness testing
Fatigue life testing
Load-displacement characteristic analysis
Dynamic force and deformation analysis
It is widely used in:
Automotive manufacturers and parts suppliers
Rubber product manufacturers
Research institutes and universities
Quality inspection and certification laboratories
The Rubber Bushing Dynamic and Static Stiffness Test Bench can comply with the following standards:
