| Abstract: | The working mechanism of plane steel gate was analysed.A fine finite element model of the plane steel gate was established.A parallel solution strategy was presented.A method incorporating the loop-unrolling technique was proposed to implement parallelization of element stiffness matrix.The preconditioned conjugate gradient method was adopted to solve the finite element sets of equations.Reasonable results with a considerably high parallel computation efficiency were obtained with the designed parallel algorithm.It is indicated that the parallel computing can reduce structural calculation time for large-scale structure analysis. |
