The Railway Rubber Pad Dynamic & Static Stiffness Fatigue Testing Machine is a specialized testing device based on microcomputer-controlled electro-hydraulic servo technology. It is primarily used to evaluate the mechanical performance of railway rubber pads and fastening systems under static, dynamic, and cyclic fatigue conditions. Designed according to relevant standards for high-speed and conventional railways, the machine can comprehensively measure static stiffness, dynamic stiffness, fatigue life of rubber pads, and overall assembled fastening system performance, meeting the railway engineering field’s requirements for high precision, high repeatability, and long-term stable operation.
Application
This testing machine is suitable for performance evaluation of railway track structures and related elastic components, including but not limited to:
Rubber pads for high-speed railways
Rubber pads for conventional railways
Elastic baseplates for track fastening systems
Complete track slab–fastening–rail assembly systems
Railway vibration damping pads, isolation pads, and elastic gaskets
Rail pads for urban transit (subway, light rail)
Material R&D, type testing, and factory inspection for railway engineering
Mechanical testing in railway institutes, testing centers, universities, and research institutions
Standards
The machine is designed to meet and cover the following standards:
TB/T 3395-2015 – Technical conditions for high-speed railway fasteners
TB/T 2626 (relevant clauses) – General technical conditions for railway track fasteners
TB/T 2329 (reference) – Technical conditions for railway elastic baseplates
TB/T 3274 (reference) – Testing methods for railway rubber products
Relevant mechanical and fatigue testing standards (reference)
GB/T 16826 – Electro-hydraulic servo fatigue testing machine
GB/T 2611 – General technical requirements for testing machines
Note: The equipment supports static stiffness, dynamic stiffness, and fatigue tests according to railway industry standards, and test methods can be expanded per user technical specifications.
