摘要
模态试验分析是了解结构动态特性的有效手段。通过模态试验,可以计算出结构的固有频率、模态振型、阻尼比等参数,为结构设计与优化打下坚实的基础。在实验教学中,通过对模态试验的基本原理、主要步骤和试验中注意事项的介绍和分析,可以指导学生完成模态实验,加深学生对理论知识的理解和掌握,提高学生的动手能力、独立思考能力和分析解决问题的能力。
Modal experiment analysis is an effective way to understand some structure dynamic characteristics.Eigenfrequency,vibration pattern and damping ratio can be got by modal experiment.Then,these parameters can be used to structural design and optimization.In experimental teaching,the introduction and analysis of modal experiment＇s basic principles,main steps and some attentions in the experiment can instruct students to complete the experiment better,deepen students＇ understanding and grip on theory,improve students＇ abilities of practice,independent thinking and solving problems.
