Pipe Pressure Straightening The Mathematical Model

Pressure straightening steel that is a simple and flexible structure is an effective method for repairing bending distorted pipe .It is necessary to research the technological parameters of straightening steel, due to lack of technological theoretical and computational method of calculating the straightening Steel important parameters that mainly rely on the experience of workers .This paper mainly studies the following areas:For the first, Elastic-plasticity theories and interrelated formulas about anti-bending deformation of steel are researched and elaborated.The second,it is effective and scientific method from Theoretical formula, Elastic-plastic deformation mechanism and FEM simulation to research important parameters of Straightening Stroke, Straightening sticks Pitch and Straightening reduction force.The third, Development of straightening machine is constrained by institutional and mold when finish an optimize research .It is essential for Institutional innovation and Mold Optimization to research in Kinematics and Principles of metal Pressure processing respectively.The fourth, Design bench and Get data. Experimental data is used to verify data obtained from the calculated formulas and the finite element simulation .Weighted and modify method is mentioned to modify the formula and finally developed Straightening Stroke Computing System, Straightening sticks Pitch Computing System and Straightening reduction force Computing System.
