N2 - This study addresses the fatigue testing requirements of large-span bridge components in complex environments by proposing a high-performance electro-hydraulic servo system that integrates a modular reaction frame, multi-channel coordinated loading, and dynamic decoupling control. The system enhances structural stiffness and natural frequency, thereby mitigating resonance risks, by connecting reaction frame groups and three-stage fixtures via scalable coupling devices. It also suppresses multi-channel coupling interference and achieves high-precision dynamic loading through velocity feedforward compensation based on structural invariance principles and reverse decoupling networks. Experimental results demonstrate that the system exhibits excellent force tracking performance in the low-frequency range and is adaptable to spatial constraints of environmental chambers, providing a reliable solution for multi-dimensional dynamic loading tests of civil engineering structures.
