With 20 years of experience in dynamics, aerospace industry and business, I can help you with your testing practices and activities to create a faithful digital twin and to qualify your product before it flies..or goes to space!

1. DIGITAL TWIN is the new graal. And it's true, that the availablity of a digital twin will improve design, productivity, reliability and of course profitabilty: less prototypes, less risk...as long as your model represents your object
2. In our business, testing is still mandatory for certification. No test, no fly!

Vibration testing, acoustic testing, Ground Vibration Testing... 

LET'S TEST, LET'S FLY

"FEM and DUT looked identical, someone thought they were twins. So they did a DNA TEST. In fact there were not twins!

When we talk of Digital Twin, let’s make sure that the virtual is actually the twin of the physical: and there is only one way to do this. TEST!!"

World-class authors describe and illustrate how structural dynamics is applied to the engineering design process

Structural Dynamics in Engineering Designcovers the fundamentals of structural dynamics and its application to the engineering design process, providing all of the necessary information to implement an optimal design process. Each of its seven chapters is written by an expert in the field and provides the reader with the structural dynamic theoretical background and its more practical aspects for the implementation of an advanced design capability.

The first three chapters are dedicated to the underlying theory of the three main processes: the fundamentals of vibration theory, the basis of experimental dynamics and the main numerical analysis tools (including reference to the finite element method). Having laid the foundation of the design philosophy, the following three chapters present the reader with the three disciplines of identification, nonlinear analysis and validation/updating. The final chapter presents some applications of the approach to real and complex engineering cases.

Key features:

• Takes a multi-disciplinary approach and contains critical information on theory, testing and numerical analysis for structural dynamics.
• Includes a chapter on industrial applications (including aircraft design and ground vibration testing), which illustrates the design process and explains how structural dynamics is applied at different stages.

The book is a must-have for researchers and practitioners in mechanical and aerospace engineering (in particular test engineers, CAE analysts and structural dynamicists), as well as graduate students in mechanical and aerospace engineering departments.
