Inverse solution of springback in bending and its application to optimal design for prebending UOE pipe;

Effects of the parameters of prebending on O-forming of pipe in UOE process;

Plate prebending for complete fracture based on automatic registration of fractured bone model

Numeric Simulation Analysis for Pre-bending Process of Automotive Subframe Hydroforming;

It briefly introduces the importance of pre-bending process for production of longitudinal submerged arc welding pipe,function of pre-bending and pre-bending procedure,and analyzes main pre-bending process parameter,such as radius of curvature of upper mould,pre-bending length and pre-bending coiling angle and pre-bending force,etc.

The processes of orientation,pre-bending,and bending of the part could be accomplished by a single compound die.

A new technology of prestress is put forward to reinforce preflexed timber beams with carbon fibre sheets.

A new technology of prestress was put forword to reinforce preflexed timber beam with carbon fibre sheet,when tranditional timber structures were short of bearing capacity or rigidity.

Overseas technique to produce pre-bending machine has been mature which have high tonnage and efficiency,but its cost is also very high.

The purpose of prebending process of longitudinal submerged arc welding pipe production line is introduced;character of roller prebending and mould press type prebending is analyzed.
