The series of products of the electro-hydraulic servo dynamic static universal spring fatigue testing machine have the characteristics of easy use, high control accuracy, and good reliability. This series of testing machines has absorbed advanced international electro-hydraulic servo dynamic testing machine technology during the research and development process, combined with the actual usage conditions of domestic users, and designed with the development concept of "modularization, modularity, and standardization". The key components of the testing machine are selected from well-known brands of similar international and domestic products or processed using advanced international technology, greatly improving the stability and reliability of the system. The overall performance of the testing machine is comparable to the international advanced product technology level.
The electro-hydraulic servo dynamic static universal spring fatigue testing machine is widely used for dynamic and static mechanical performance testing of materials and components, including compression, low cycle, and high cycle fatigue testing of materials and components. By configuring corresponding accessories and testing software, it can be used for crack propagation and fracture mechanics of various materials, as well as other mechanical tests. Configure high and low temperature chambers for conducting high and low temperature mechanical tests.
