Design and experiment of double redundancy electrical-mechanical actuator;

Research on Redundancy Control System of BLDCM;

Triplex-redundancy control system for direct-drive-valve;

The method simulates the kill events of single vulnerable components and multiply vulnerable components or redundant components to ‘Model of Filling Boxes with Balls’, in which the area of each box is equal to the component’s vulnerable area.

This thesis gives a low cost solution based on CAN bus for redundant flight control system through performance analysis of Fieldbus Technology, which is a popular technology in automation field in recent years.

Study on the determination of residual strength for expansive soil;

The result shows that the installation of bolts can effectively enhance the peak and residual strength of the bolted rock body and that bolts strengthen the strength of residual of the rock body more than they do the strength of its peak Moreover,with the increase of t.

By the simulation test, it is proved that the function of rock bolt is to raise the residual strength of broken surrounding rock around roadway, and the broken surrounding rock is made into a reinforced arch.

Assessment method for remaining strength of corroded pipeline and its application;

Theory foundation for remaining strength assessment methodology is presented and assessing formula for relative assessment methodology is educed based on individual basic assumption.

API 579 and F101 are two kinds of common codes in computing the remaining strength of corrosion pipeline for local metal loss.

The influences of varietis of resins,particle size and amount of luminous materials,thickness of coating film and et al to the after-glow brightness of the coating film are compared to obtain the optimum formulation of luminous fluorocarbon paint.
