Airplanes are designed to stay aloft with the help of wings on both sides. In operation at cruising speed, the wings are subjected to load as much as the weight of the whole aircraft. However during maneuver, the wings are subjected much higher load and stress and this stress should be sustained by the wings within its limit load without causing permanent deformation to the structure. In order to...
In this paper, the finite element modelling method of micromachined airflow omnibearing level posture sensor is presented. Through building the three-dimensional model of the sense organ, the finite element analysis of the sensor is carried out by using ANSYS software. The results show that: (1)Using the symmetry of the sense organ, a half-model is built first, which is convenient in modeling and...
This paper deals with the maximum quality factor in relation to the dimensions of an inner-coil type thin-film inductor with a closed magnetic circuit. We used an equivalent circuit, taking into account of flux distribution and eddy currents in the magnetic film as well as stray capacitances. The proposed inductor yields the maximum quality factor Qmax=32 at f=20 MHz. The quality factor is mainly...
