Abstract

The invention relates to a power station indirect dry cooling system, and provides a system and a method for structural analysis of an indirect dry cooling tower based on APDL (ANSYS Parametric Design Language). The method comprises the following steps of: 1) according to geometric outside dimension of the indirect cooling tower, defining geometric parameters of the indirect cooling tower, and establishing a parameterized geometric model of the indirect cooling tower; 2) defining the unit type, real constants and material constants of the indirect cooling tower; 3) defining unit meshing size, performing self-adapting meshing division, and establishing a finite element model of the indirect cooling tower; 4) respectively applying parameterized loading for the indirect cooling tower under five loading working conditions (dead load, live load, wind load, temperature load and earthquake load) and performing computational analysis; and 5) performing combination of loading working conditions, and extracting computed results. Through the application of the system, the full process control of the indirect cooling tower from modeling to calculation can be realized. Meanwhile, the indirect cooling tower can be optimally designed by adjusting the value of each parameter. A large amount of repeated work is avoided, and the efficiency of structural analysis and design can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of power generation and relates to an indirect air-cooling system of a power station. It proposes an APDL-based finite element analysis system and method for an indirect air-cooling tower structure, which can be applied to the structure design and structure optimization of an indirect air-cooling tower in actual engineering. Background technique [0002] In my country, the air cooling system of power plants is widely used in the north where coal is rich and water is scarce. In recent years, due to the continuous strengthening of environmental protection and economic rationality requirements, the application range of air cooling systems has been expanding. [0003] With the continuous emergence of large air-cooled units, the height of the air-cooling tower has been far greater than the height limit of conventional cooling towers in the "Code for Hydraulic Design of Thermal Power Plants" and the limit of 165m ...
