Mechanical product design is crucial in many engineering field and lots of industries. CAE simulation has been widely applied for predicting virtual product design for a few decades to reduce the cost and shorten the design life cycle. Because of complicated geometry, material/geometrical nonlinearity and complex conditions, it is painful to efficiently and accurately simulate and predict ...

A Piezoelectric Directional Microphone is demonstrated based on a bio-mimetic design inspired by the parasitoid fly Ormia ochracea using the PiezoMUMPs multi-user foundry. The device simulation was conducted using COMSOL Multiphysics® software which achieves a directional sound field response and frequency band of 3.5 KHz to 4.5KHz. The sensitivity of the device is 3.8nV/pa.

Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet these requirements, we designed, using COMSOL, a small, easy to read MEMS capacitive force sensor, with ...

This paper describes the thermal and structural combined simulation on COMSOL Multiphysics® of a Microwave (MW) Fin Taper (FT) Spatial Power Combiner (SPC) Power Amplifier (PA), based on rectangular Waveguide (WG). In the SPC based PA's, the captured power is feeded by microstrip transmission lines (μSTL’s) to Monolithic Microwave Integrated Circuit (MMIC) Solid State Power Amplifier (SSPA’s). ...

The thermal management of silicon detectors and related electronics through micro-structured silicon cooling plates is gaining considerable attention for high precision particle trackers. Micro-fluidic circuits are etched in a silicon wafer, which is then bonded to a second wafer to obtain a cooling circuit. Because mono-crystalline silicon is structurally close in characteristics to brittle ...

A hydraulic loader crane (HLC) is a machine used for cargo handling. It's structural project is complex due to several requirements. In this case, validation with simulation is advantageous. The objective of this paper is to evaluate the stresses of a HLC and compare it with results obtained from structural calculation according to DIN EN 12999 standard. The simulation's results obtained with ...

The Finite Element Model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream face of the dam .The fluid on the upstream side is considered to be incompressible, inviscous, and irrotational. Here the effect of fluid compressibility is analyzed by the use of COMSOL Multiphysics® software. The impact of water pressure on the upstream face of ...

Absorber tubes are one of the most critical components of parabolic trough Concentrated Solar Plants, which is very likely get damaged such as crack and mass loss. Therefore, the monitoring of their structural health via Non-Destructive Testing (NDT) techniques is regarded as essential for preventing them from being significantly defective and thereby reducing maintenance cost. Non-contact ...
