Most technical systems become smart over time, therefore those systems will have improved safety and comfort functions. An example is a new development by Westfalia-Automotive. A new generation of smart tow bars, equipped with a sensor system, including distance sensors, is able to ... En savoir plus
This paper presents a simulation model of a rotary damper filled with a magnetorheological fluid (MRF). The most important characteristic of the MRF is the variable viscosity, which can be controlled by an external magnetic field. In the simulation model, the fluid is described as a ... En savoir plus
Thermal elastohydrodynamic lubricated (TEHL) contacts occur very frequently in drive technology and thus in gear drives. In this presentation, the implementation of a finite element based TEHL simulation approach for gear contacts in COMSOL Multiphysics® software is shown. The physically ... En savoir plus
The objective was to make a visualisation application for the pupil's lab of the University of Applied Sciences Bielefeld. The application serves as a supplement for a workshop. It should provide a better understanding of a fuel cell, to visualize important influences and collect first ... En savoir plus
As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a ...

For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and ... En savoir plus
Lithium ion battery safety problem has attracted the whole world’s attention essentially after the explosion of Samsung Note 7. This work mainly deals with the study of the generation, characteristics and prevention measures of the battery fire. Firstly, the heat generation rate of ... En savoir plus
This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to ...

Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it ... En savoir plus
Microwave heating has many advantages over the traditional heating method, such as needing shorter time, saving more energy, and being easier to control. But there still are some problems.(1) Themal runaway still exists because the reflection and absorption of microwave by the reactants ... En savoir plus
