Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The embodiment of the present invention provides a group topology radially loaded ring stress superposition method. This method uses d'Alembert's principle to establish a static model on the micro-segment of the ring, uses the section method to obtain the distribution function of each static parameter of the ring under the action of a single radial load with the assumption of extension, and then uses the superposition method, The function of each static parameter of the grouped topology radially loaded ring based on the extension assumption is obtained, which significantly improves the accuracy, universality and authenticity of the static analysis of the ring, and is better clo...

Abstract

The invention discloses an extension hypothesis grouping topology radial loading circular ring statics analysis method, and the method comprises the following steps: 1, cutting out a micro section on a circular ring, and establishing a statics model of the circular ring under the action of a single radial load through a cross section method by adopting the Alembert principle; 2, establishing a distribution function of each statics parameter of the circular ring under the action of a single radial load based on extension hypothesis through the statics model; 3, obtaining a function of each statics parameter of the grouping topology radial loading ring based on the extension hypothesis by using a superposition method.

Description

technical field [0001] The invention relates to the field of mechanical stress distribution and elastic deformation of materials, in particular to a method for superimposing stress and deformation of a grouped topology radially loaded circular ring with an extension assumption. Background technique [0002] The ring structure is widely used in the fields of machinery, hydraulics, chemical industry, water conservancy, transportation and aerospace, such as gear rings, automobile hubs, impellers of centrifugal pumps, valve plates of plunger pumps, stators and rotors of motors, gyroscopes and aeroengines and other structures. Their working states can be divided into stationary, fixed-axis rotation and multi-axis rotation. In engineering practice, the static and dynamic characteristics are the main concerns, especially in the case of high load, high speed and high precision requirements. When the annular structure bears unbalanced radial force and tangential force, the stress d...
