Support of Dynamic Measurements Through Similitude Formulations

چکیده

Abstract Up to now, similitude methods have been used in order overcome the typical drawbacks of experimental testing and numerical simulations by reconstructing full-scale model behavior from that scaled model. The novelty this work is application theory not as a tool for predicting prototype dynamic response, but supporting, eventually validating, measurements polluted noise. Two Aluminium Foam Sandwich (AFS) plates are analyzed with Digital Image Correlation (DIC) cameras. First, an algorithm blind source separation problems extract information about excitation; then, SAMSARA (Similitude Asymptotic Models Structural-Acoustic Research Applications) method applied both force spectra velocity responses reconstruction curves demonstrates results coherent quality measurements: when spatial pattern resonance recognizable, then overlap. Instead, displacement field just one well identified, exhibits discrepancies. Therefore, reveal be interesting understanding if set reliable or their should underestimated, especially light expanding range approaches which can important noisy observations.

Similitude And Theory Of Models

The concepts of Similitude, Dimensional Analysis and Theory of Models are presented and used in this chapter. They constitute important theoretical tools that allow scientists from many different areas to go further on their studies prior to actual experiments or using small scale models. The applications discussed herein are focused on thermal sciences (Heat Transfer and Fluid Mechanics). Usin...

Remembering Similitude Terms in CBR

In concept learning, inductive techniques perform a global approximation to the target concept. Instead, lazy learning techniques use local approximations to form an implicit global approximation of the target concept. In this paper we present C-LID, a lazy learning technique that uses LID for generating local approximations to the target concept. LID generates local approximations in the form ...

Unified Scaling of Dynamic Optimization Design Formulations

In this article, we explore scaling in dynamic optimization with a particular focus on how to leverage scaling in design studies. Here scaling refers to the process of suitable change of variables and algebraic manipulations to arrive at equivalent forms. The necessary theory for scaling dynamic optimization formulations is presented and a number of motivating examples are shown. The presented ...
