On-line transformer monitoring based on vibration analysis

There are three kinds of seismic analysis methods: response spectrum method, time history method and stochastic vibration method.

Vibration Analysis of S385 Diesel Engine and Its Influences on Vehicle;

A survey of engineering structural damage identification methods based on vibration analysis;

Vertical vibration analysis of transversely isotropic saturated soils with elastic superstratum;

MP2 and B3LYP methods with AUG-cc-pVDZ basis sets are performed to optimize the 10 kinds of possible isomers of phosphorous clusters P_(5) and their cations and anions,and the converged results are verified by vibrational analysis in order to get the stable equilibrium geometries.

For all optimized configurations,there is no imaginary frequency in vibrational analysis.

The force constant matrixes of all critical poins (the reactants,the transition state and the products)of the reaction CH3+H2O→CH4+OH were computed by vibrational analysis at the UHF level for 6-31G basis sets.

Based on an analysis of vibration of rotor-bearing system, the method for measuring rotor amount of unblance with hard bearing and soft bearing system is proposed and the theory base for design and application of tire dynamic balancing machine is given.
