| Abstract: | In order to solve the problem of deflection compensation of upper roller for large marine bending machine,using FEA optimization method based on ANSYS,the amount,locations and the imposed loads of bearing rollers of 21 m large marine bending machine were optimized reasonably and the deflection compensation measure was proposed.The deflection of the upper roller and beam in optimizing loads and overall role model in the working load were obtained through finite element analysis method.After compensation,the ... |
