Reduction of the engine vibration and the dynamic forces transmitting from engine to the automotive body structure has always been an important part of automotive research. Automobile engineers face the task of creating a mechanism to absorb these vibrations and provide a smooth ride. The usage of Motor Mounts is the best solution for dampening the effects of vibrations and oscillations. This ...

This elaboration presents a pre-study on automatic rotor construction for the flywheel energy storage system dedicated to operate in the levitation mode. The optimization profile model is used as a basic profile source. The 3D flywheel shape is generated on the base of obtained profiles. Eigenfrequencies are calculated to validate the operation on rigid mode. A steel and aluminum based ...

Due to the advantages of induction heating as a method for precise and efficient local heating, it is perfectly suited for thermal shrink fitting of a gear wheel on a shaft. In this work, a simulation model was established to study the induction heating of a gear wheel, its thermal expansion as well as the shrink fitting process. It was possible to find an appropriate geometry for the induction ...

A quasi static indentation test on a laminate composite has been investigated numerically and experimentally. In particular, the test has been implemented by COMSOL Multiphysics® and optimizing the Finite Element and mesh. In addition, the numerical strain results have been validated by the comparison with the respective experimental deformation data that have been obtained by fiber Bragg ...

A Polysilicon H-beam is a micro-machined structure consisting of two primary members connected by a third member of much lower width and much greater aspect ratio. This structure exhibits interesting vibration behavior at specific frequencies which are known as resonant modes. A ‘mode’ may be described as a specific physical shape that the vibrating object assumes at peak oscillation amplitude ...

Isogrid plate components are widely used in aerospace structures because of their greater stiffness to weight ratios compared with thicker plates of the same material. Isogrid plates consist of flat plates conjoined with thin ribs in specific geometric patterns. The purpose of this study was to investigate the applicability of COMSOL Multiphysics for the determination of buckling loads and modes ...

Accelerometers are successfully commercialized MEMS devices. COMSOL Multiphysics® has been used in the modeling, simulation and optimizing of this design. The piezoresistive accelerometer is made up of a square proof mass with flexures supporting it. The piezoresistors are placed near the proof mass and frame ends of the flexure and the springs. There is an elongation or shortening of the ...

Different facilities for hadrontherapy have been built in the recent past. AISHa ion source has been designed by keeping in mind the typical requirements of hospital-based facilities, where the minimization of the mean time between failures (MTBF) is a key point together with the maintenance operations which should be fast and easy. The study of some critical parts of the facilities: the ...

The geometrical design and material choice for a refractory lining requires a good understanding of its thermo-mechanical behavior. Design engineers clearly need a tool for fast and efficient computation of thermo-mechanical state of refractory linings under various conditions. However, standard simulation models and their solutions suffer as the linings are composed of many refractory blocks in ...
