Interactive Design of an Electrostatic Headphone Speaker Using COMSOL Server™
An electrostatic headphone includes many interrelated design elements that affect the frequency response of the headphone and the users listening experience. Xi Engineering Consultants (XI) partnered with Warwick Audio Technologies (WAT) to investigate the complex behavior of one-side ... 詳細を見る
Numerical Vibration Analysis of Impacted CFRP Specimens Using COMSOL Multiphysics® Software
The vibration behavior of carbon fiber reinforced composites (CFRP) specimens with impact damage is presented in order to evaluate if an before/after modal analysis can be used as a non-destructive testing method to detect delaminations. The impact damage is modeled by decreasing the ... 詳細を見る
Prediction of the Loudspeaker Total Harmonics Distortion Using COMSOL Multiphysics® Software
For automotive applications, simulation methods are used to get the best audio acoustic performance. Because a loudspeaker is a non linear device, the sound pressure in the vehicle includes harmonics which are mainly created by the force factor, suspension stiffness and voice coil ... 詳細を見る
Investigation of Scattering Effects in Colloidal Systems
When the particles in a colloid come close to each other, multiple scattering in ultrasonic beams is no longer negligible and crowded particle effects emerge. The presence of each particle affects the scattering of all others, leading to coupling effects. We investigate the interaction ... 詳細を見る
Bloch Waves in an Infinite, Periodically-perforated Sheet
Bloch waves in infinite periodic structures – much in vogue in the present metamaterial age – can be conveniently studied by COMSOL Multiphysics® software. This is demonstrated by a simple, yet rich two-dimensional example: a perforated sheet with square symmetry. Instead of plane waves ... 詳細を見る
Simulating Acoustic Combustion Chamber Eigenmodes to Facilitate Combustion Stability in Rocket Engines
Airbus Safran Launchers is the market leader in Space Launch services. Rocket engines are among the most powerful machines that exist. The core of the rocket engine is the combustion chamber where in the case of liquid propellant rocket engines, fuel and oxidizer are injected, mixed and ... 詳細を見る
Piezoelectric Surface Acoustic Wave (SAW) Device with Simulated Poling Condition
FEM (Finite Element Method) modelling software such as COMSOL Multiphysics® can be a powerful tool for modelling the behavior and response of piezoelectric materials and devices [1]. Devices based on piezoelectric crystals are particularly well suited, because the polarization magnitude ... 詳細を見る
Modeling of Near-Field Ultrasonic Levitation: Resolving Viscous and Acoustic Effects
Ultrasonic levitation is a novel technology for contactless handing of various objects. It is already used in various manufacturing processes where it is important to keep untouched surface. In this paper we introduce a model of so-called near-field ultrasonic levitation which allows ... 詳細を見る
Development of a Package for a Triaxial High-G Accelerometer Optimized for High Signal Fidelity
Acceleration is an important quantity to be measured in high-speed dynamics. A new piezoresistive sensor for the measurement of high-amplitude, short-duration transient accelerations of up to 100,000 g has been developed at the Fraunhofer EMI. Its figure of merit (sensitivity x resonance ... 詳細を見る
Virtual Commissioning of Large Machines with COMSOL Multiphysics® Software
In addition to using advanced functions built-into the engine of the COMSOL Multiphysics® software, we integrate dynamic properties of rotating components that are measured or pre-computed. Here, it is shown how to integrate fluid-film characteristics and take advantage of post ... 詳細を見る
