| Abstract: | By use of the three-dimensional elastic contact finite element method,the numerical simulation has been adopted for the compensation process of the compensation device of press brake,and the load-deflection distortion curve of the upper surface of workbench has been obtained. By comparing with the deformation curve of the lower surface on slider,the design parameters of the machine compensation device has been revised. The curve coincidence of workbench and slider has been highly improved and the manufactur... |
