[Bu Adresi (link) Görme Yetkiniz Yok BEDAVA'ya Üye Ol Sitemizden Faydalan....] Nova: standalone utility for quick modeling of the response of layered poroelastic noise control treatments. NOVA software is a very powerful tool that will help you design and optimize the acoustic properties of a multilayer material without having to spend too much time on long and expensive testing.ESI NOVA 2018.0 | 445.2 mb NOVA software allows you to optimize the acoustic absorption and transmission loss of several materials configurations in a very short time because of its user-friendly interface and extremely fast computing time. Features - Nova includes two modules: . Mid and high frequency modules based on transfer matrix method with correction for finite size effects. . Low frequency module based on FEM/BEM provides the most advanced models for porous materials (rigid, limp, felts, elastic, screens, and perforated panels). - Allows unlimited combination of material layers including elastic, visco-elastic foam, fiber, felt, screen, septum, solid, perforated plates and fluid to simulate real-life acoustic problems. - Accounts for orthotropic, sandwich and composite panels. - Allows for frequency dependent properties. - Includes automatic detection and coupling of domains (elastic and fluid). - Studies the effects of different boundary conditions and various types of excitations (plane waves, diffuse acoustic field, mechanical, pistons, point source, turbulent boundry layer, etc.). - Includes extensive materials database. - Includes scripts to calculate SEA input parameters: modal density, loss factor, radiation efficiency, wave numbers, etc. - Includes a script that allows the study of heterogeneous materials by the Parallel Transfer Matrix method (PTMM). - Includes micro-macro (bottom-up) scripts for foams and fibers. - Accounts for finite size effects in the high frequency module. - Allows simulation of impedance and bazooka tests, transmission loss tests and random incidence absorption tests. - Analyzes narrowband and 1/3 octave band. - Computes a large number of parameters: absorption and reflection coefficient, surface impedance, transmission loss, dissipated powers, equivalent damping loss factor, space averaged velocity and pressure response, insertion loss, radiation efficiency, etc. Website Home Page : Kod:
