商品描述
The aim is at providing the reader with knowledge on both basic and advanced topics in the vibrations of structural systems categorized as either discrete or continuous. The emphasis is on numerical methods of solution with a Java programming framework that accompanies the book. Reference will be made to numerical solutions based on the contemporary discretization techniques ranging from the commonly used finite elements to more advanced mixed forms as well as boundary element methods. In terms of practical applications, the topic of modal analysis is of central importance in structural dynamics where response of the system is captured in the modal space through the modal characteristics, namely modal shapes and frequencies. Specifically, identification modal analysis which might be classified as experimental and/or operational modal analysis, focuses in the determining modal characteristics of a given structural system from a set of measured responses in the form of transient signals.Thus, vibration-based methods for damage detection and localization taking advantage of machine learning techniques are currently a topic that is seeing rapid development because of its relevance to structural health monitoring. Finally, in terms of numerical analysis, the book presents an open-source software platform named 'Symplegma'. This is developed using Java with the Apache-Groovy-Java virtual machine-based language serving as the scripting mechanism for adding special-purpose software modulus. This platform is presented in depth and provides a work space for the reader to implement the material presented in the book and to explore areas of application that are of interest to him/her.
商品描述(中文翻譯)
本書的目的是為讀者提供有關結構系統振動的基本和進階主題的知識，這些系統可分為離散型或連續型。重點在於數值解法，並附有一個基於 Java 的程式設計框架。本書將參考基於當代離散化技術的數值解法，這些技術從常用的有限元素法到更先進的混合形式以及邊界元素法。就實際應用而言，模態分析在結構動力學中具有核心重要性，系統的響應透過模態特徵，即模態形狀和頻率，在模態空間中被捕捉。具體而言，識別模態分析可分為實驗模態分析和/或操作模態分析，專注於從一組以瞬態信號形式測量的響應中確定給定結構系統的模態特徵。因此，基於振動的損傷檢測和定位方法，利用機器學習技術，因其與結構健康監測的相關性而迅速發展。最後，在數值分析方面，本書介紹了一個名為 'Symplegma' 的開源軟體平台。這個平台是使用 Java 開發的，並以基於 Apache-Groovy-Java 虛擬機的語言作為添加特殊用途軟體模組的腳本機制。這個平台將深入介紹，並為讀者提供一個工作空間，以實施書中所呈現的材料，並探索他/她感興趣的應用領域。
