Abstract

The invention discloses a design method of a topological insulator cellular model of magnetorheological machinery. The design method comprises the following steps: constructing a parallelogram-shaped matrix by adopting a magnetorheological elastomer; using the two metal three-legged rods as scatterers to be filled in the base body; removing four corners of the matrix through difference set operation to form a topological insulator cellular model of the magneto-rheological machine; and destroying the mirror symmetry of the magnetorheological mechanical topological insulator cellular model by rotating the angle of one scatterer, so that a controllable forbidden band for separating different topological phases is obtained, that is, the frequency range of a topological transmission channel of the magnetorheological mechanical topological insulator cellular model is determined to be adjustable. According to the invention, the magneto-rheological mechanical topological insulator cellular model with an adjustable topological transmission channel frequency range is constructed by using the magneto-rheological elastomer as a matrix and the metal tripod as a scatterer in the matrix, so that the model is suitable for complex and changeable actual conditions.

Description

technical field

[0001] The invention relates to the technical field of mechanical topological insulators, in particular to a design method for a cell model of a magnetorheological mechanical topological insulator. Background technique

[0002] The tuning of mechanical topological insulators can be achieved by tuning physical parameters, geometric parameters, and structural topology. When the basic element material of the mechanical topological insulator is selected and the design is designed, the characteristics of its energy band structure are also fixed. The elastic wave frequency that can be controlled is also a fixed frequency band. Under complex engineering and mechanical working conditions Therefore, it is particularly important to develop mechanical topological insulators that can adjust the bandgap frequency range after the structural design is completed.
