The dynamic behavior of the rotor-bearing system of the slider-crank mechanism was studied in this paper. Based on the finite element method, a model of the rotor-bearing system was developed. The calculation results of the numerical simulation demonstrated that dynamic response of the shaft depended on both the bearing stiffness and the dynamic property of the slider-crank such as rotor rotate speed.
This paper described a new flicker test standard developed in National Institute of Metrology (NIM) for the calibration of voltage fluctuation and flicker. It meets the requirement of both flickermeter and flicker source according to the IEC 61000-4-15.
The main objective of the present work is an investigation of the computation methods applicability in a cylindrical sealed space, two different geometry constitute methods are introduced, multi-zone model and fluid dynamic model were discussed. Computation results of the two calculation methods are within err of 15% in radial direction, and has different results in the vertical direction upright...
Harmonic pollution monitoring and control is the key to an accurate estimate of harmonic impedance, and thus an accurate assessment of public connection points of the harmonic emission level. This paper analyzes the link under the star-shaped and triangular three-phase asymmetrical power systems derived established a three-phase unbalanced power system harmonic impedance matrix estimation model. Model...
The main objective of the present work is an investigation of the heat transfer induced by the fire in a cylindrical sealed space. The thermal smoke flow geometry characteristics in cylindrical sealed space were discussed, LES and mixture fraction methods were applied to conduct numerical transient analysis. Computed results has validated the smoke flow course in simulation experiments. The study...
This paper has discussed the fire-induced smoke flow geometry characteristics in irregular confined spaces, and use LES and mixture fraction numerically methods to compute the smoke flow in a round cross sectional confined spaces. Computed results has validated the forecast of the flow course, showing that the smoke layer descending faster upper the fire source than other locations. Along with the...
Fusing out-of-sequence information is a problem of growing importance for multi-sensor target tracking systems due to sensors embedded in complicated network architectures. The problem of how to deal with these updates has received much attention in recent years and has been solved optimally and suboptimally by various authors. Most of the solutions treated only the problem of updating a track by...
