Pre-and post-processing Acoustic Simulation software "MNOISE"
MNOISE Software
User-friendly software for pre- and post-processing of acoustic simulations.
Acoustic requirements of automotive components have increased in importance over the recent years due to legal regulations, lightweight design, higher customer demands and especially due to the introduction of electrical vehicles with lower masking noises and high tonal noise content. MNOISE supports the simulation engineer at the acoustic evaluation of components based on Finite Element (FE) simulations. In combination with common FE tools, it enables an acoustic evaluation even in an early concept design phase. Especially global dynamic characteristics of components are responsible for the acoustic performance. Those only can be influenced significantly in an early concept phase. Using MNOISE critical areas and acoustic hotspots can be detected on the virtual component by evaluating acoustic near field measures. Based on these results, design improvements can be done before a physical prototype is available. Development time and prototyping costs can be reduced. *For more details, please download the PDF or contact us.*

basic information
**Features** - Automatic generation of load tables for Finite Element solver based on complex load histories from MBS run-up simulations - Meshing forces of spur gears train - Computation of acoustic parameters (surface noise level, acoustic power, mobility) - Fourier transformation to prepare load data for the frequency response analysis - Evaluation of the acoustic performance of components. -Detection of critical speeds and/or resonance frequencies (order cut, speed cut, frequency band evaluation) - Psychoacoustic measures for individual points (Loudness, Roughness, Sharpness) **Modules** - **MNOISE Basic Module** : MNOISE basic module includes all pre- and post-processing capabilities necessary for virtual acoustic evaluation of your component based on FE frequency response results. Acoustic measures of the near field are analyzed and clearly displayed. With MNOISE basic module one can detect critical areas and acoustic hotspots of the virtual component, which can be used as starting point for design improvements. - **MNOISE Gear Module** : MNOISE gear module is a multi-body solver especially designed to solve the parametric excitation resulting from the mesh stiffness variation of spur gears. The necessary information of the mesh stiffness can be imported directly from KISSsoft. MNOISE gear solves the equation of motion of the spur gears and exports the run-up load tables for a subsequent FE response analysis. The acoustic behavior of mesh excitation is especially important for the evaluation of transmission units and eDrive systems. *For more details, please download the PDF or contact us.*
