Abstract

The invention relates to a design analysis method for a gas turbine gas inlet device, which belongs to the technical field of gas turbines. The precise stimulating analysis is carried out on the working conditions of a local part and a section of a gas inlet device by adopting a computer stimulating technology. The method comprises the following steps of: (1) model establishment: firstly, primarily designing a two-dimensional viewgraph and carrying out ANSYS three-dimensional modeling on the part needing to be calculated and analysis under the condition of confirming the sizes of all parts of the two-dimensional viewgraph; carrying out finite element division of an analysis object according to the concrete technical requirement and precision requirement needing analysis and calculation of the analysis object so that a computer can analyze and calculate each unit by utilizing enough resources; and (2) loading analysis: A. strength and linear buckling analysis: containing stress distribution, displacement distribution and load factors in calculating results; B. flow field analysis: analyzing the static pressure, total pressure and speed flow line of a system and respectively obtaining a speed vector distribution picture, a static pressure cloud picture and a total pressure cloud picture of a typical section.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, in particular to a design and analysis method for gas turbine intake devices. This method is mainly used in the construction of special ground test benches for gas turbines and gas turbine generating sets, and is an essential equipment for gas turbine applications. Background technique [0002] At present, without using computer simulation technology, the design of the existing gas turbine air intake device is calculated by hand and by experience; therefore, there are great limitations. For example, manual strength, stiffness, flow field, and thermal analysis of more complex components, flow channels, and pipelines have problems such as huge workload, correctness of conclusions, and size of errors. [0003] There are two types of equipment for the test bench: special equipment for the test bench and self-contained equipment for the gas turbine. The air intake device is a very important dev...
