Kinematic analyse and optimization design of a new type of flying shear mechanism;

Flying shears equipment is one of the important continuously imported metallurgical equipment in china.

A succinct and practical method for calculating mechanical parameters of flying shears is obtained.

This paper studies the effect of variant transmission plans of drum flying shears on the conditions of the forces on low driving gears of the hollow shaft sleeves and analyzes the forces on the shear mechanism and low eccentric driving shafts.

Optimal mechanism design of shearing machine using genetic/particle swarm hybrid algorithm;

Optimal mechanism design of a shearing machine;

This not only cuts off the numble of variats and the computing load,but also perfects optimum design for shearing mechanism in shearing machine further.

PID adjustor in flying shear length control system;

Analysis of blade speed in flying shear control system;

The dynamic static forces of plane hinge four bar flying shears are analysed with analytic methods.

Reconstruction has been made on an eccentric plier which is the only such machine of Russian made in the 1950s still remaining in China by computer control of which the model for speed tracker algorithm and dynamic correction is presented in the paper.

This thesis introduces the composition of the structure and determines the synthesis structure form of the offset crank slider and crank connecting rod mechanism by the example of Φ12 cold rolled thread steel FJJ12 flying shear.
