Study on Analysis Principle of Spatial System Method for a Hydraulic Steel Gate

The target of this paper is to ensure that the spatial system method has scientific and efficient rules follow in structural analysis a hydraulic steel gate, overcome problems randomness fuzziness process. Based on idea part whole, principle for gate systematically studied using combination theoretical calculation, finite element analysis, prototype testing. First, verified, with calculation used authenticity geometric modeling, appropriateness type, rationality meshing, accuracy constraints, load application when analyze structure (panel, arm, beam). specific practical feasible principles are provided. Second, carried out method. Finally, test verify results results, maximum absolute error static displacement 0.58 mm relative stress 9.19%, which verifies key technical restricting transition from plane preliminarily solved. This first exploration made popularization method, lays foundation improving quality efficiency design.
