This book was released on 1991 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: La sensibilité de dispositifs à ondes de Rayleigh aux contraintes mécaniques et thermiques dynamiques a été étudiée théoriquement et expérimentalement afin de trouver des coupes insensibles à ces perturbations extérieures. Deux familles de coupes de quartz à simple rotation localisées autour des anglaes PHI=0#O, THETA=10#O, PSI=30#O) ET (PHI=O#O, THETA=45#O, PSI=45#O) ont été trouvées comme étant peu sensibles aux effets statiques avec un bon accord entre les modèles théoriques et les vérifications expérimentales. De récentes manipulations ont permis de mettre en évidence leur faible sensibilité aux perturbations thermiques dynamiques, avec un gain d'un facteur 10 à 20 par rapport à la coupe de référence (ST,X)

Download or read book Mechanical Vibration written by William John Palm and published by . This book was released on 2007 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Model, analyze, and solve vibration problems, using modern computer tools. Featuring clear explanations, worked examples, applications, and modern computer tools, William Palm's Mechanical Vibration provides a firm foundation in vibratory systems. You'll learn how to apply knowledge of mathematics and science to model and analyze systems ranging from a single degree of freedom to complex systems with two and more degrees of freedom. Separate MATLAB sections at the end of most chapters show how to use the most recent features of this standard engineering tool, in the context of solving vibration problems. The text introduces Simulink where solutions may be difficult to program in MATLAB, such as modeling Coulomb friction effects and simulating systems that contain non-linearities. Ample problems throughout the text provide opportunities to practice identifying, formulating, and solving vibration problems. KEY FEATURES Strong pedagogical approach, including chapter objectives and summaries Extensive worked examples illustrating applications Numerous realistic homework problems Up-to-date MATLAB coverage The first vibration textbook to cover Simulink Self-contained introduction to MATLAB in Appendix A Special section dealing with active vibration control in sports equipment Special sections devoted to obtaining parameter values from experimental data

Download or read book Space Debris written by Heiner Klinkrad and published by Springer Science & Business Media. This book was released on 2006-09-01 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future evolution of the debris environment will be forecast on the basis of traffic models and possible hazard mitigation practices. The text shows how large trackable objects will have re-entry pinpointed and predictions made on related risk assessment for possible ground impact. Models will also be described for meteoroids which are also a prevailing risk.
