COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin ... En savoir plus

The simulation of a micromirror using polyimide as the structural material is presented. The simulation was used to verify the initial design parameters and to explore the different characteristics of the electromechanical device. For simulation simplicity the electrodes are integrated ... En savoir plus

High frequency side-scan sonar, to be fitted on a miniaturized submersible explorer, have been simulated and built. The purpose of this study is to see if COMSOL Multiphysics® can be used to predict the performance of the sonar, especially the beam width, setting the resolution of ... En savoir plus

移动电话产品向更薄的趋势发展，装入手机中的微型扬声器能使用到的音腔空间也就日趋减少。为了高效利用手机内部空间，手机音腔设计时往往导通扬声器位置周围的小空间作为其音腔，扩大音腔体积。与此带来的问题是，因手机内部空间限制，导通管或导通孔规格较小，产生了声谐振效果。谐振频率点往往位于重要的中频段，使声压级中频段曲线出现波谷，影响声学性能和听感效果。 本文说明了声谐振产生的原因，并通过电力声类比，用理论方法估算出声谐振频率点的大致范围。为了解决声谐振产生的问题，我们使用 COMSOL Multiphysics® 准确模拟出扬声器声腔的 SPL 曲线，通过 SPL ...
