摘要

摘要: 混合试验是一种将数值模拟与物理试验相结合的新兴结构抗震试验方法，是一种评估非线性结构和系统性能的先进试验方法。该文提出了一种采用电动式激振器的混合试验系统设计方法。该方法以电动式激振器为作动器，并采用MATLAB软件、STM32系列单片机、串口通信技术、等效力控制方法以及位移传感器、力传感器等构建了一套包含硬件和软件的完整的混合试验系统。为了检验所设计混合试验系统的性能，选用粘弹性阻尼器作为试验子结构，对加入粘弹性阻尼器的单自由度框架结构进行了混合试验分析，结果表明：该文设计的混合试验系统数据通信可靠，整个系统可行、有效。

Abstract: 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.
