Book excerpt: The report, the second part of a series giving data for design against acoustic fatigue, has been prepared in order to draw together the results of research in acoustic fatigue and to present them in a form directly useable in aerospace design. Future work in this series will deal with endurance of titanium alloy structures under simulated acoustic loading, near field compressor noise estimation, stress response of box and control surface structures, structural damping and stress response of skin-stringer panels with stringers of relatively low flexural stiffness.

Book excerpt: The report contains acoustic fatigue test procedures, methods of calculation and results for various structural elements. Section I presents a method to determine the natural frequencies of initially unstressed box structures that are rectangular in section. The second section provides a method of estimating the R.M.S. stress in internal plates of a box structure subjected to random acoustic loading. Section III provides a method of estimating the sound pressure levels within the intake duct of a supersonic fan or compressor due to buzz saw noise.

Download or read book Sonic Fatigue Design Guide for Military Aircraft written by and published by . This book was released on 1975 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate methods are presented for estimating the acoustic loading, structural response, and fatigue life of military aircraft structures. This report presents over sixty tables, 110 charts and nomographs, five computer programs and forty worked examples illustrating the use of the different methods. These results stem from a review and evaluation of over 300 references related to the various topics associated with sonic fatigue. This report is organized into independent sections with the subject classification allowing for ease of identification and future extension as required. Sufficient detail is provided so that the entire handbook stands as an independent source of sonic fatigue design data.

Download or read book Sonic Fatigue Design Techniques for Advanced Composite Aircraft Structures written by Ian Holehouse and published by . This book was released on 1980 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combined analytical and experimental program was conducted in order to develop a semi-empirical sonic fatigue design method for curved and flat graphite-epoxy skin-stringer panels. A range of multi-bay panels was subjected to high intensity noise environments in a progressive-wave tube. Shaker tests were also performed in order to provide additional random fatigue data. Finite- element analyses were carried out on the test panel designs, generating static strains and frequencies. Multiple stepwise regression analysis was used to develop the sonic fatigue design method. Design equations and a nomograph are presented. Comparisons of sonic fatigue resistance between graphite and aluminum panels were also carried out. The design method developed is presented as a self-contained section in this report and is suitable for practical design use.

Available in PDF, EPUB and Kindle. Book excerpt: A combined analytic and experimental program was conducted to determine sonic fatigue design properties of bonded structural sections based on skin-stringer-frame design commonly applied in aircraft and to formulate data and criteria for the development of sonic fatigue resistant designs of such structure. The FM73/BR127 adhesive system was used in the bonding of beam and multibay panel test specimens with 7075-T6 aluminum alloy skins and substructure. The metal surfaces that were bonded were treated with a phosphoric acid anodizing process that complied with the BAC-5555 specifications. Beam tests were conducted under narrow band shaker excitation and multibay panel tests were conducted under broadband acoustic excitation. The test results were evaluated and used in the development of a semi-empirical method for predicting sonic fatigue lives of multibay panels in acoustic environments. The range of applicability of the sonic fatigue design method is only partly determined. The sonic fatigue lives of the multibay acoustic test panels compared favorably with the lives of riveted panels of comparable size and skin thicknesses.
