Abstract: The purpose of this paper is to address the problems of unclear process, inefficient method, and low quality in establishing geometric model and finite element model of hydraulic radial gate structure in the process of finite element analysis. Using the APDL parametric language of the general finite element calculation software ANSYS, the specific process and corresponding APDL command were given for the rapid establishment of high-quality geometric model and finite element model of radial gate. This method can ensure the authenticity of geometric model, correctness of finite element model, appropriateness of boundary conditions and rationality of analysis results. As a result, the key technical problems in the process of finite element analysis of radial gate were solved, and the design quality of the gate was enhanced. Based on the parametric modeling, the relevant parameters in gate design can be accurately and rapidly modified, and the design efficiency of gate can be boosted. The proposed method can shed light on high-quality design and analysis of the same type of gate structures, and lay a technical foundation for improving and enriching the current gate design specifications.
