Abstract: The present invention discloses a dynamic straightening method for a left/right tilt. The method includes: drawing an unevenness curve according to a distance from a shapemeter to a surface of a plate, where there are a plurality of unevenness curves; using a barycentric formula to obtain a first barycentric coordinate of each unevenness curve; calculating a tilt value of a straightening roll corresponding to each unevenness curve according to the first barycentric coordinate of each unevenness curve; determining an unevenness curve of a current straightening roll; adjusting the straightening roll according to the tilt value of the straightening roll corresponding to the unevenness curve, to straighten the plate; and going back to the step of determining an unevenness curve of a current straightening roll until the plate is totally straightened. The present invention improves plate straightening accuracy by dynamically adjusting parameters of the straightening roll.

Abstract: A method for checking the design of locking assemblies is provided. A pressure on each contact surface and a torque that can be transferred by a spindle and a bushing after locking assemblies are locked are calculated. The calculated torque is compared with the designed maximum transferable torque to calculate a torque safety coefficient. Based on a minimum fit clearance, a resultant stress of components is calculated and is compared with a yield strength of the material of the components to calculate a strength safety coefficient of the components. A pre-tightening force of the bolts is obtained according to a given pre-tightening moment of the bolts. A maximum equivalent stress of the bolts is calculated to obtain a safety coefficient of the bolts. This method is able to be applied to the manufacturing of the locking assemblies.
