摘要：
Hybrid testing is an emerging structural aseismic testing method that combines numerical simulation and physical tests, and it is an advanced test method for evaluating nonlinear structures as well as system performance. It presents a design method for a hybrid testing system using an electric exciter. In this method, the electric exciter is used as an actuator, and MATLAB software, STM32 series MCU, serial communication technology, the equivalent force control method, a displacement sensor, and a force sensor are used to build a complete hybrid testing system including hardware and software. In order to test the performance of the designed hybrid testing system, aviscoelastic damper is selected as the test substructure, and the hybrid testing analysis of a single-degree-of-freedom frame structure with the viscoelastic damper iscarried out. The test results show that the data communication of the designed hybrid testing system is reliable, and the whole system is feasible and effective. © 2020, Engineering Mechanics Press.
