Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and 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.

[0027] A method for the optimal design of the column structure of the gear grinding machine based on the analysis of dynamic characteristics, such as figure 1 shown, including the following steps:

[0028] S1. Establish the finite element model of the column of the gear grinding machine

[0029] In step S1, due to the relatively complicated structure of the column, it is very difficult to perform three-dimensional modeling in finite element software. In the embodiment of the present invention, the three-dimensional solid model of the column of the gear grinding machine is established through th...

Abstract

The invention provides a structure optimization design method for a gear grinding machine stand column on basis of dynamic characteristic analysis. A finite element model of the gear grinding machine stand column is established; dynamic analysis is carried out on the stand column and the inherent frequency and vibration mode of the stand column are determined; independent single-order topology optimization is conducted on the stand column with the design space unit volume of the stand column as a constraint and the inherent frequency of the stand column as an objective function; according to the single-order topology optimization result, space quality distribution with light structure quality and improved low-order frequency is searched for, and the internal structure of the stand column is optimized according to distribution of unit density of the stand column. Stress distribution of the structure of a gear grinding machine is more reasonable, the optimal distribution condition of materials is obtained, and the materials are economical. In addition, analysis and design stages of a machine tool structure are applied, repeated prototype testing and scheme correction operations are reduced, the design cycle is shortened, development cost is lowered, and efficiency and high quality are achieved in structural design of a machine tool with theoretical basses as guidance.

Description

technical field [0001] The invention belongs to the field of mechanical structure optimization design, and in particular relates to a method for optimal design of a column structure of a gear grinding machine based on dynamic characteristic analysis. Background technique [0002] Gears are the basic components of mechanical transmission systems. They are used to transmit motion and power between any two or more axes in space. The quality and level of mechanical products are largely determined by their transmission performance and load-bearing capacity. Grinding is the most commonly used method for gear finishing, so the development of profile grinding machines is of great significance to gear processing. [0003] At present, developed countries are at an advanced level in the research and manufacture of gear processing machine tools. There are already gear grinding machines that can process external gears and internal helical gears and have been commercialized. Under the ba...
