Abstract: This paper conducts research on the design and performance testing of a double-rod hybrid energy-dissipating viscous damper. Firstly, based on an independent design concept, the structural design of the damper is completed using a 3D modeling method. Secondly, by means of the control variable method, dynamic tension-compression vibration tests are carried out on the damper using dynamic and static test benches under different frequency and rated load conditions, and the energy-dissipating performance curves of the damper are obtained. Finally, the test results are compared with the relevant theoretical formulas for performance on which the damper design is based, verifying the consistency between the test results and theoretical expectations. The research results prove the feasibility of the designed double-rod hybrid energy-dissipating viscous damper scheme from a practical perspective, and provide directions for the subsequent design optimization of such dampers.
