The traditional analysis of the leaf spring just implemented a simplified mechanical model without considering the friction between the leaf springs. In order to do better in designing the leaf spring with variable cross sections, this paper firstly constructed the parameterized model of the taper leaf spring, and then applied the contact theory to add contact element to simulate the friction between the leaf springs in the FE analysis. After these steps, the assembly of the prestressed, the stiffness, the damping ratio and the fatigue life of the leaf spring could be achieved. It shows that the analysis and computation of taper leaf spring based on FE contact analysis can reflect the actual situation more comprehensively after comparing the results with those calculated with traditional way and those recommended by industry .

“…In a wide temperature range frequency change of AT-cut quartz crystal wafer is small, so this paper chooses a AT-cut thin circular quartz wafer whose diameter is 14mm and thickness is 0.16mm. Using the ANSYS [6] finite element analysis software, we have analysed its internal stress under the radial force along the X axis. The result is showed in Fig.…”

Combining the energy limit theory and the ANSYS finite element simulation analysis, this paper has designed the new integrated quartz crystal resonator and has used oscillator circuits to carry on the experimental comparison on its temperature-frequency characteristic in high-low temperature chamber. The experimental results show that the curve of its temperature-frequency characteristic is cubic in the coordinate system, which is basically consistent with that of the single electrode resonator. The frequency change of each resonator on the same substrate is basically the same when they are in the same circumstance and stimulation. According these similarities, this paper can implement differential processing on output frequencies of different resonators on the same substrate, which can effectively restrain the influence that temperature imposes on frequency.
