| Abstract: | Taking a tower of concrete cable-stayed bridge with A-line shape as an example ,we used APDL to research the finite element parametric modeling method of the bridge tower based on ANSYS .At first ,the related feature extraction algorithm was studied and feature points of the point cloud model were exacted .Then the finite element parametric model for the tower was constructed using ANSYS ,finally the structure of the model was analyzed and the related mathematical constraint relations were established .Thus the coercion of parametic for finite element model was realized ,and the cycle time of finite element model of construction was cut down . |
