Study on guarding against sliding policy of friction haulage system based on wavelet transform;

Based on the finite difference method,the relationship between the spiral-grooved parameters and kinetic properties such as the load capacity of hydrodynamic pressure,the axial thrust force and the circumferential resisting force was analyzed theoretically.

LIM traction system of Guangzhou Metro Line 4 vehicles;

Electric traction system of metro vehicle for Beijing Batong Line;

Design of 4-pulley wagon-relocating traction system;

Hauling System for Cable Erection of Runyang Suspension Bridge over Yangtze River;

The key technologies in design and construction of the superstructure of Runyang Suspension Bridge,such as the erection of catwalks,the main stand hauling system and special lifting equipment for steel girders,are presented.

In consideration that the numbers of the wire strands of the Suspension Bridge of Runyang Changjiang River Highway Bridge are great and the strand hauling distance is long, the single-rope, round-trip hauling system is used for erection of the catwalk strands, while the double-rope, round-trip hauling system is used for erection of the main cable wire strands.
