From the laboratory to the living room: COMSOL as a remote teaching and research tool
At University College London, Applied Analytical Chemistry MSc course, we have used COMSOL Multiphysics as an alternative to laboratory-based student research projects. Use of computational modelling enabled students to complete their research work remotely while gaining experience in ... Read More
Digital development of Automotive Sound System
Automotive manufacturers have to continuously reduce their vehicle development cycle to keep up with the dynamic customer demand for latest technologies and to be ahead of the competition. Automotive subsystems have to be developed in the least possible time, using minimal resources ... Read More
Modelling of an Innovative Directional Ultrasonic Atherosclerosis Treatment Device
Atherosclerosis prevalence keeps increasing worldwide because of the sedentary lifestyle and aging of the population. It is a pathology which is characterized by the build-up of plaque on the artery walls. While it has no incidence at the beginning, the blood flow can be severely altered ... Read More
Generic Speaker Grille Apps
For automotive applications, HARMAN is using simulation and equalization methods to optimize audio systems. The fidelity of an audio system depends on many characteristics like the number of loudspeakers, the speaker packaging as well as the position and orientation of the speakers in ... Read More
Development of improved ultrasonic transducers for medical surgery
Finite element modelling of surgical transducers has been performed and is described. Ultrasonic transducers vibrating at around 25 kHz are used in orthopaedic surgery to cut bone. The high acoustic impedance of the metal blades used in these devices couples energy more efficiently to ... Read More
Numerical investigation of structured materials for vibration control
Periodical architected structures comprising reticulated beams or trusses have proven capable of controlling wave propagation at different frequency scales. Moreover, recent progress in 3D printing techniques has paved the way to their actionable application in various fields, i.e., ... Read More
Duct silencer modeling with COMSOL Multiphysics®
Duct silencers are used to reduce noise in Heating, Ventilation and Air Conditioning (HVAC) as well as noise from exhaust gas chimneys. For a duct silencer, an important trade-off has to be made between the achieved noise reduction and the pressure drop. Using an example model, we will ... Read More
Noise and Vibration Simulation of a Vacuum Cleaner Robot Gearbox
A gearbox used in a vacuum cleaner robot is evaluated regarding noise and vibration in COMSOL Multiphysics®, using the Multibody Dynamics and the Acoustics Module. The real gearbox is powered by a DC motor and consists of four plastic helical gears forming a gear train and is used to ... Read More
The Development of an Analytical Model for the Acoustics of a Porous Melamine Foam Material
COMSOL Multiphysics® has proven to be an invaluable “virtual laboratory” tool in assisting our development of a new generation of efficient analytical models describing the acoustics of highly porous fibre and foam materials. From the definition of the physical relations describing the ... Read More
