Analysis of lateral deflection of prestressed I-|girder in the prestressing;

Numerical simulation of the bending deformation of a casing;

Calculation of bending deformation of beam(plate) considering geometric nonlinearity;

The bending deformation of the aspherical bending lapping tool under the action of bending moment was analyzed according to its deformation feature in high speed lapping process.

The paper comprehensive study three respects: the influence upon bending deflection caused by three primary aspects such as gravity,pull of the mouth of well and rotate speed of drillstring.

For resolving the problem of bending deflection of overhang shaft,it is macroprogram that is applied to compensate the errors of machining deflection timely.

The calculation of bending deflection is always required in analyzing stiffness of the continual beams.

A study on bend deformation equation of ring elastic slice and solution;

Several ways to reduce deformation are proposed.

Based on the mechanics model of ring throttle slice of telescopic shock absorber on a linear pressure, by the boundary constraint and deformation continuity condition, the general solution of differential equation of throttle slice deformation was got, and with mathematical transform, the analytic formula of throttle slice deformation was established.

The results show that the overbending distortion of the broach can be avoided by straightening and special tool fixed tempering after marquenching.

The new and the traditional techniques of rectifying bending distortion with flame areapplied to rectify the bending dstortion of bead welding of the steel plate edge and the Tee-beamtest piece.

Reactors used in chemical industry must satisfy rigidity requirements to ensure the bending distortion to be controlled within the tolerated range as well as strength requirements to prevent breakage.
