Electro hydraulic servo dynamic and static universal testing machine

1Introduction:

The electro-hydraulic servo dynamic static universal testing machine (testing system) is a specialized testing equipment, and its configuration and structural form vary according to different application scenarios. In the development process of our company's dynamic and static fatigue testing machine (testing system), based on the development and manufacturing experience of Bocai International Electro Hydraulic Servo Dynamic Testing Machine Company, combined with the usage habits of domestic users, we adoptedThe development concept of "unitization, modularization, and standardization" has achieved the purpose of "providing domestic users with dynamic fatigue testing machines with higher cost-effectiveness". The key supporting components of the equipment are selected from similar international and domestic products. According to the requirements of the test object, suitable servo controllers, servo valves, and key components of the hydraulic system are selected, which not only ensures the stability and reliability of the system, but also greatly improves the cost-effectiveness for user applications.Our aim is to provide customized testing systems for our customers!

The electro-hydraulic servo dynamic static universal testing machine is mainly used for dynamic and static mechanical performance testing of materials and components, including tensile, compressive, bending, 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, fracture mechanics, and other mechanical tests of various materials. Widely used in material testing fields such as aerospace, shipbuilding, research institutes, enterprise new product development, and enterprise product testing.
