Characterisation of Structure-Borne Sound Source Using Reception Plate Method

Characterisation of Structure-Borne Sound Source Using Reception Plate Method

A laboratory-based experiment procedure of reception plate method for structure-borne sound source characterisation is reported in this paper. The method uses the assumption that the input power from the source installed on the plate is equal to the power dissipated by the plate. In this experiment, rectangular plates having high and low mobility relative to that of the source were used as the ...

Fast Sound File Characterisation Method

This article describes a fast technique of characterization of sound documents based on a statistical measure of the variation of the signal. We showed that a very limited sampling was sufficient to obtain a reasonable performance of the characteristic while being 100 times faster to calculate than a complete sampling. During preliminary tests, we carried out a first validation of our approach ...

Independent characterization of structure-borne sound sources using the in-situ blocked force method

The vibro-acoustic behavior of systems and components in modern vehicles play an increasingly important role in the development process of high quality products in automotive industry. In order to characterize the numerous mechanical, electrical and mechatronic systems, many of which embody significant sources of structure-borne sound and vibration, advanced measurement techniques are required....

Hybrid Isolation of Structure - Borne Sound

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
