Download or read book Validation of Projectile Transient Response Models for the Study of Pressure Oscillations in Guns written by David A. Hopkins and published by . This book was released on 1993 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results that provide a validated simulation approach to study the behavior of projectiles subjected to transient in-bore loadings. In this study, the PXR6353 instrumented round was modeled. The approach used features vibration studies of the components of this projectile. This includes a comparison of the vibration modes determined by finite element techniques with those modes determined using experimental modal analysis techniques. The ANSYS finite element code was used to generate the analytic model. Both impact and shaker excitation methods were used in the experimental modal analysis phase. The direct comparison between analytical and experimental data showed that the finite element model correctly captured the dominant modes of vibration of the projectile.

Download or read book Hydrodynamics of High Speed Marine Vehicles written by Odd M. Faltinsen and published by Cambridge University Press. This book was released on 2006-01-09 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics of High-Speed Marine Vehicles, first published in 2006, discusses the three main categories of high-speed marine vehicles - vessels supported by submerged hulls, air cushions or foils. The wave environment, resistance, propulsion, seakeeping, sea loads and manoeuvring are extensively covered based on rational and simplified methods. Links to automatic control and structural mechanics are emphasized. A detailed description of waterjet propulsion is given and the effect of water depth on wash, resistance, sinkage and trim is discussed. Chapter topics include resistance and wash; slamming; air cushion-supported vessels, including a detailed discussion of wave-excited resonant oscillations in air cushion; and hydrofoil vessels. The book contains numerous illustrations, examples and exercises.
