| 摘 要： | 实模态综合技术发展至今已日趋成熟,然面考虑阻尼的复模态综合技术尚不完善,滞变阻尼下的复模态综合技术更是处于探讨阶段。为了研究滞变阻尼下结构的频率特性及振型特性;为了研究传统的实模态综合技术在考虑滞变阻尼时的复特性,本文用复模拟的方式较为深入地探讨了实修改自由界面法的复频率与复振型,同时通过算例作了验证。

| Abstract: | The real modal synthesis techniques are being perfected day by day,but the complex modal synthesis technique with damping is still imperfect,especially the com- plex modal synthesis technique with hysteresis damping.To study the frequencies and shapes of the structures with hysteresis damping and the complex charaeteristics of the traditional real modal synthesis technique with hysteresis damping,this paper presents the improved free-interface method in complex simulation we have re- searched and a good number of examples to show the results in calculation. |
