Mageba is an internationally renowned manufacturer of bridge bearings, expansion joints, structural damping, and seismic isolation systems, headquartered in Switzerland. From the Jungfrau Railway in Switzerland to the Hong Kong Zhuhai Macao Bridge in China, and from the Charnacle 1915 Bridge in Türkiye to the landmark sea crossing channels on all continents, Magba's products always represent the Swiss quality of "precision, durability and reliability".
Magba requires strict full-scale mechanical performance verification for every bridge bearing it manufactures. With the rapid development of Magba's business in China and the Asia Pacific region, especially in participating in super large cross sea bridge projects, its production of giant bowl shaped and spherical bearings has put forward extremely high requirements for testing equipment - with super large tonnage loading capacity, high-frequency dynamic response accuracy, and long-term load stability.
The 2000 ton electro-hydraulic servo dynamic compression shear testing machine delivered by Jinan Xinguang Testing Machine has the following characteristics:
1. Ultra large load-bearing capacity and super strong stiffness
-Ultra high stiffness four column frame: adopting a four column+large cast steel base structure, the overall stiffness far exceeds conventional standards, ensuring minimal deformation of the whole machine under 20000kN ultimate load and ensuring the accuracy of deformation data under large tonnage.
-Large effective testing space: equipped with a super large workbench and a track type mobile car, it can easily push giant supports weighing several tons into the testing area, solving the problem of large components being unable to enter or move.
2. Leading dynamic measurement and control technology in China
-High performance electro-hydraulic servo dynamic system: The equipment has the ability to control the dynamic load spectrum and can simulate dynamic cyclic loading in the frequency range of 0.01-30Hz, which is used to accurately determine the equivalent damping ratio and hysteresis curve of the support.
-Multi channel coordinated loading: realizes precise coupling control of vertical loading (2000 tons), horizontal shearing (matched according to standards), and corner mechanism, simulating the real state of the support under earthquake and complex stress conditions.
3. High precision measurement and control that meets international standards
-High precision sensor group: equipped with imported or high-precision domestic load sensors and displacement sensors, the system accuracy is better than 0.5 level.
-Dedicated global standard software: The Xin Guang measurement and control system comes pre installed with multiple test templates, allowing for one click generation of multilingual test reports that comply with Magba's global quality management system requirements.
