摘　　要：以导弹舵面为研究对象,针对高温环境对结构模态试验激振方法提出的特殊要求,分析了热模态试验可能采用的激振方法的可行性,并对可行的热模态激振方法进行优化设计及试验验证。结果表明:对于采用石英灯辐射加热方式进行热环境模拟的导弹舵面热模态试验,比较适合的激振方法为采用激振器通过耐高温加长激振杆施加激振,以及通过振动台进行基础激振的方法。Aiming at the special request of the modal test excitation method within a thermal environ- ment, the feasibility of excitation method which is likely used to rudder thermo-modal test is analyzed, and the optimum design and validate test for the viable excitation method are presented. As the result, for the rudder thermo-modal test using quartz-lamp radiant heater, there are two excitation methods is appro- priate. One method is by vibration exciter with the longer high-temperature shaker stinger to provide a ex- citation, the other method is by using vibration shaker tables to provide a driven-base excitation.
