The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper concerns the violins family: the geometry and the vibratory propagation of this instrument is very complicated ...

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the electromagnetics, the electronics (including the control of the process), the mechanics and the fluidics with respect to ...

This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric actuators, which are placed on an elastic plate. The next considerations concern the feasibility of the proposed ...

Landmines are an open problem in many countries of the world. They cause injuriesand death and no technique proposed to date guarantees fast and 100% reliable detection alone. To this purpose, at the Humanitarian Demining Laboratory of “La Sapienza” University of Rome, several solutions are being studied. In this paper, numerical simulations of a prototype thermal detection system are reported, ...

In COMSOL Multiphysics it is possible to implement and simulate several independent models in parallel. This can be meaningful when the different models are coupled to each other by some kind of interaction. If a part of the geometries is identical in all models, this part can be reduced in that it is implemented in only one of the geometries. In the other geometries only its solution towards ...

In this paper, we will present simulation results obtained using COMSOL RF module for the current along a wire antenna in both frequency and time domains. The structure is excited through a lumped (voltage or current) source at its center. For the frequency domain simulations we compare the results with the Numerical Electromagnetics Code (NEC-4) and for the time domain results we compare them ...

Neural disorders like epilepsy, Parkinson’s disease and Alzheimer’s disease have become a major area of concern because of their complexity and the huge number of occurrences. At present, most of the treatments are based on drugs and external nerve stimulation demanding critical care. This study aims at the design and simulation of an implantable micro-electrode which can lead to better ...
