Abstract: The present invention belongs to the technical field of bridge wind tunnel test devices, and provides a free-vibration testing device for simulating nonlinear stiffness of a bridge rigid model. By flexibly designing the shape and the size of the rigid arc-shaped supporting arms, the spatial positions of the fixed bearing pulleys, the initial strains of the springs, and other parameters, this device can achieve multiple vertical-torsional coupled nonlinear stiffness modes, and also can achieve nonlinear stiffness only in the vertical direction while maintaining constant torsional stiffness, so as to carry out large-amplitude vertical-torsional coupled flutter and large-amplitude vertical galloping measurement tests under the nonlinear stiffness of bridge structures. During the large-amplitude vibration process of the model, the springs can always remain in a vertical state and will not experience lateral vibration, ensuring that the testing device has stable low damping, mass, and stiffness.
