Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that stresses generated do not exceed the endurance strength of the material. In this paper, structural mechanics ...

Proportional solenoids are well-known and used in a wide range of applications today. This paper is about methods of influencing the characteristic force-stroke-curves of magnetic actuators by means of different pole geometries. The conical design of the stator pole which is mostly used to accomplish proportional solenoids is analyzed by both a simple analytic reluctance model and a FEM model ...

Since the advent of Terhertz(THz) technology, improving the THz emission power has been one of the major research goal. One of the methods to increase the THz emission power is to increase the coupling of excitation laser light to the dielectric substrate.The field of nano-plasmonics exploits light-matter interactions at nanometer scale. With the help of metallic nano-structure at ...

In this paper modeling and simulation results of a thermal bimorph is capable of producing increased displacement for increasing temperatures are presented. Thermal bimorphs are popular actuation technology in MEMS (Micro-Electro-Mechanical Systems). Bimorph actuators consist of two materials with different coefficients of thermal expansion. The main objective of this work is to investigate the ...

A dynamic mathematical model, based on physical and transport properties and mass and energy balances, was developed for the simulation of unsteady convective drying of agricultural products (fruits and vegetables) in static bed conditions. The model utilizes water sorption isotherm equations and the change in solid density due to the shrinkage phenomenon. The aim of this article is to describe ...

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle wax leads to a phase change that allows mass transport via capillary flow prior to combustion in the flame. ...

The Helmholtz Coil generates a uniform magnetic field. The commercially available large-size Helmholtz coils prove to be very expensive. This paper describes the economical method of designing and construction of a Helmholtz coil. COMSOL Multiphysics AC/DC Module simulated results and actual results were compared in this study. The coil serves as a component in the system for Hyperpolarisation of ...

Vacuum distillation furnaces (VDFs) are employed for purification and consolidation of heavy metals from their dendritic forms which are entrained with molten salts. The VDF is an induction heated furnace which is operated at a temperature of 700-1400 °C and at a pressure of 0.01-600 torr. To arrive at the adequate design of such type of furnace, magnetic field and temperature distribution need ...

Carbon fiber (CF) reinforced polymer composites (CFRP) have begun to replace Al-Zn-Mg alloys in applications which require high strength-to-weight ratios. The anisotropy of CFRP composites is a result of melt crystallized extrusion techniques that impart an inherent directionality to the CFs and the associated material’s properties. Electrical conductivity was modeled across the entire CF ...

Pulse-echo FEM simulation is seldom found in literature for ultrasound imaging array probes, since the complete modeling of such device is extremely complicated. Nevertheless, the 2D FEM described in the present work was successful, thanks to the following design procedure (see figure): Two piezoacoustic models were employed, one for transmission of the pressure wave into the acoustic domain, ...
