地面颤振模拟试验是一项以真实飞行器结构作为试验对象，并利用激振器模拟非定常气动力的颤振验证试验技术。本文通过在地面颤振模拟试验的基础上引入热环境模拟设备，进一步研究热颤振地面模拟试验技术。建立了综合考虑多工况的气动插值点优化方法，然后利用Kriging代理模型构建了适用于时变温度场中结构的非定常气动力降阶模型，同时设计了气动加热环境地面模拟及热环境下结构的激励与响应测试方案，最终基于钛合金机翼模型搭建了热颤振地面模拟试验系统，并对时变颤振边界进行跟踪测试。试验结果表明，在激振力控制器的设计控制频带内试验结果与仿真结果吻合较好，但鲁棒控制器较窄的控制带宽限制了热颤振地面模拟试验的适用范围。

Ground flutter simulation test is a flutter verification experiment technology for real aircraft structures， which uses exciters to simulate unsteady aerodynamic force. In this paper， the thermal environment simulation scheme is used in this technology to establish the thermal flutter ground simulation system. An aerodynamic interpolation point optimization algorithm is proposed based on the weighting of modal shapes. An unsteady aerodynamic reduced-order model for time-varying structure is constructed by using the Kriging surrogate model. After the simulation scheme of aerodynamic thermal environment and the measurement method of high-temperature structure’s response signal are designed， the experiment system based on the titanium alloy wing model is completed. Finally， time-varying thermal flutter boundary tracking and testing is carried out. The testing results show that the testing accuracy is acceptable when the controller is within the preset frequency range， but the narrow control bandwidth of robust controller limits the application of the thermal flutter ground simulation test.
