چکیده
SOUND AND VIBRATION/JANUARY 2001 Often times, people ask some simple questions regarding modal analysis and how structures vibrate. Most times, it is impossible to describe this simply and some of the basic underlying theory needs to be addressed in order to fully explain some of these concepts. However, many times the theory is just a little too much to handle and some of the concepts can be described without a rigorous mathematical treatment. This article will attempt to explain some concepts about how structures vibrate and the use of some of the tools to solve structural dynamic problems. The intent of this article is to simply identify how structures vibrate from a nonmathematical perspective. With this being said, let’s start with the first question that is usually asked:

متن کاملDamage identification of structures using experimental modal analysis and continuous wavelet transform
Abstract: Modal analysis is a powerful technique for understanding the behavior and performance of structures. Modal analysis can be conducted via artificial excitation, e.g. shaker or instrument hammer excitation. Input force and output responses are measured. That is normally referred to as experimental modal analysis (EMA). EMA consists of three steps: data acquisition, system identificatio...
