Shock absorber telescopic fatigue life testing machine

Shock absorber telescopic fatigue life testing machine

1、 Introduction: Electro hydraulic servo fatigue testing machine is widely used for dynamic and static mechanical performance testing of materials and components, including tensile, compression, fatigue and other tests of materials and components.
The research and development process of the fatigue testing machine for air spring shock absorbers draws on the development experience of internationally renowned electro-hydraulic servo dynamic testing machine companies. Based on the "GB/T13061 Air Spring Rubber Airbag for Automotive Suspension" standard, the development concept of "unitization, modularization, and standardization" is adopted, and advanced international electro-hydraulic servo dynamic testing machine technology is absorbed, combined with the actual usage conditions of users. The key supporting components of the electro-hydraulic servo dynamic testing machine are selected from well-known international and similar products. Greatly improving the stability and reliability of the system, the key units and components of the system adopt advanced international technology, and the overall performance is comparable to the technical level of internationally renowned dynamic testing machine companies. This series of products has the characteristics of easy use, high control accuracy, and good reliability.
The 80kN air spring shock absorber fatigue testing machine is one of the latest series of dynamic and static universal testing machines developed by our company. The main unit of the testing machine, constant pressure servo pump station, and other key components are designed by our company. The servo valves, seals, and other key purchased components are all well-known international and similar products, 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.
