Introduction

The research and development process of the electro-hydraulic servo fatigue series testing machine draws on the development and manufacturing experience of internationally renowned electro-hydraulic servo dynamic testing machine companies, adopting the development concept of "modularization, modularity, and standardization", absorbing advanced international electro-hydraulic servo dynamic testing machine technology, and designing it based on the actual usage conditions of domestic users. The key supporting components of the electro-hydraulic servo dynamic testing machine are selected from well-known brands of similar international and domestic products.
Main purpose: Used for fatigue testing, dynamic stiffness, static stiffness, longitudinal resistance testing, assembly buckle pressure testing, and other projects on high-speed railway fasteners, sub rail pads, and other components in the laboratory. The replacement of attachments is also applicable to various components such as concrete structural components, sleepers, steel strands, anchorages, and various trusses for dynamic and static mechanical performance testing.
