In this paper will be presented how an electronic system and its components will respond in case of an impact of an external electromagnetic pulse (EMP). In the first instance the coupling process of transient electromagnetic pulses into electronic systems will be shown. Out of that the ... 詳細を見る
Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic ... 詳細を見る
Machines with rotating components are prone to vibrations because an imbalance of the rotor would always act as a harmonic excitation force to the machine. Thus oscillations close to the natural frequencies are tried to pass through fast in the run-up and cast-down or even completely ... 詳細を見る
In this contribution we present a COMSOL Multiphysics® example of a disk piezoelectric ceramic transformer (D-PT) coupled with a bipolar NPN transistor to form an auto-oscillator. The comparison between the simulations and the measurements made on our prototype are found to be in good ... 詳細を見る
Hazardous for the transmission lines is not only the static ice load, but also the aerodynamic instability of iced cables. It can lead to large amplitude oscillations at low frequencies. Also, twisting due to asymmetrical iced cables may increase the fatigue rate. In extreme events, ... 詳細を見る
The objective of the research is to design a broadband energy harvester device through the multi-beam approach and non-linear trapezoidal geometry approach. The performance of two piezoelectric PZT-PZN polycrystalline ceramic composition samples are simulated in COMSOL Multiphysics®, and ... 詳細を見る
The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from a two arm Archimedes spiral coil. The performance of particular interest is knowledge of the radiated magnetic field H and electric field E in the ... 詳細を見る
We present the results of full-waveform time-dependent finite-element modelling of coupled seismoelectromagnetic wave propagation in fluid-saturated porous media. To describe the seismoelectric response of the system a new set of equations is developed which couple the poroelasticity ... 詳細を見る
Classical hydraulic dampers are flexible devices that are used to attach a component to a mounting base. Vibration amplitude reduction can be achieved by improving the old technique of suspension by bringing in application of Magnetorheological or Electrorheological fluid in it. Due to ... 詳細を見る
Acceleration is an important quantity to be measured in high-speed dynamics. A new piezoresistive sensor for the measurement of high-amplitude, short-duration transient accelerations of up to 100,000 g has been developed at the Fraunhofer EMI. Its figure of merit (sensitivity x resonance ... 詳細を見る
