The complete formation of concavity was recorded and was found that the concavity almost finished when the whole cross section solidified.

Its basic connotation is to express the ambition of poet s desire for gaining achievements and the indignation of their unrecognized talents.

Nonlinear dynamic response analysis of unbalance-rubbing coupling faults of rotor-ball bearing-stator coupling system;

This paper introduces the principle and classification of mechanical balance,the allowable amount of unbalance and balance precision in the process of mechanical manufacturing,the balance testing method and its principle,the dynamic balancing system,and digital signal processing technology for rotating parts.

The analysis results show that putting dynamic balancing in practice and eliminating amount of unbalance is benefit to improving the tool system.

Through combining the actual condition of the piping layout of offshore platform and calculating the unbalance force caused by pulse,it confirms the method is the best.

Unbalance forces of the engine is the main reason for vibration of motorcycles.
