1CSEM, Switzerland

In this poster we present the results of the strategy for calibrating the COMSOL Multiphysics® model to simulate the laser bonding process (LADB) of Mems chips. A specific aspect of this work is to calibrate the COMSOL Multiphysics® heat model loss by measuring with a miniature ... Read More

THERMO-ELASTIC STUDY OF A SPACE ACTUATOR BALL BEARING SET

Zain Mansoor1, Claudia Allegranza1
1ESA/ESTEC, Keplerlaan 1, 2200 AG, Noordwijk, Netherlands

Ball bearings are used in vast majority of mechanisms for space applications (such as Solar Array Drive Mechanisms, pointing mechanisms or reaction wheels) in order to provide low friction and smooth motion between parts. These applications differ from the ground ones due to space ... Read More

Numerical Modelling and Validation of Induction Melting of IN713C for Investment Casting

This study is focused on the optimization of a- YBa2Cu3O7-x (YBCO) based bolometer working above 77 K. The temperature distribution on the superconductor surface and the temperature profile through the whole system (bolometer plus plate with heaters) were studied at the working point ... Read More

Hybrid 2D/3D fully coupled electrothermal model for three-core submarine armored cables

Juan Carlos del-Pino-López1, PedroCruz-Romero1
1Universidad de Sevilla, Spain

It is a fact that IEC 60287 standard introduces important errors in the computation of the armor losses of submarine three-core lead sheathed armored cables, since the twisting of phases and armor wires is not considered. This results in an overestimation of cable size, and hence its ... Read More
