Problems solved by technology

At present, many studies on gear dynamics do not consider or simplify the stress distribution of the ring. Due to the limitations of the analysis technology of the stress distribution of the ring, an analysis method for the stress distribution of the ring under the action of the tangential concentrated force is especially needed.

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0032] The embodiment of the present invention proposes a highly applicable method for stress superposition of tangentially loaded circular rings in mirror topology. First, the static model of the ring under the action of a single tangential concentrated force is established on the micro-segment of the ring, and the distribution of internal forces of the loaded ring is obtained. The stress distribution under the action of concentrated force is calculated, and then the superposition method is used to calculate the stress distribution of the mirror-image topological tangentially loaded ring. This method can also be used to solve the stress distribution of typical periodic structures such as stator and rotor of rotating electrical machines and ring components in micro-devices.

Abstract

The invention discloses a mirror topology tangential loaded circular ring stress superposition method. The method comprises the following steps that a static model of a circular ring under the actionof single tangential concentrated force is established on a micro section of the circular ring; calculating a distribution function of the tangential stress and the radial stress of the circular ringunder the action of a single tangential concentrated force through a static model; and obtaining a distribution function of the tangential stress and the radial stress of the mirror topology tangential loaded circular ring by utilizing a superposition method. Compared with the prior art, the method has the characteristics of innovation, high efficiency, accuracy, universality and the like. According to the method, the relationship between the tangential concentrated force distribution and the stress distribution can be studied.

Description

technical field [0001] The invention relates to the field of mechanical stress distribution of materials, in particular to a method for stress superposition of a mirror image topology tangentially loaded circular ring. Background technique [0002] As early as in ancient China, the ring structure was used by the working people. The water wheel, also called the crane, is an ancient water-lifting irrigation tool and a kind of running machine developed by the ancient Chinese working people by making full use of water resources. . Water buckets are arranged around the waterwheel. During the rotation of the waterwheel, the water buckets draw water to irrigate the land. The water wheel can be simplified as a ring structure, and the gravity generated by the water bucket can be regarded as a tangential force exerted on the ring structure. It is necessary to study the tangential force applied on the ring to the stress distribution of the ring, because the material that satisfies th...
