Engine loss prediction method, device, equipment and medium

Abstract

The invention provides an engine loss prediction method, device and equipment and a medium, and in the method, the deformation of a guide pipe and a seat ring after the engine is subjected to interference load and working load is obtained by establishing a finite element model of the engine and adopting a finite element analysis mode. The guide pipe and the seat ring are divided into multiple layers from the height, the circle centers of the guide pipe and the seat ring on each layer are determined through deformation, and then the axes of the guide pipe and the seat ring after interference loads and working loads are borne can be determined. Therefore, the eccentricity of the guide pipe and the seat ring at different positions and the axis included angle between the guide pipe and the seat ring can be determined, the possible deformation condition of the guide pipe and the seat ring can be evaluated in the design stage of the engine, and automatic and accurate prediction of the loss of the engine is achieved.
