The invention relates to a design method of a metal rubber component, relating to a design method. The invention solves the problems that the input of material parameters is difficult and the influence law of the performance parameters of the metal rubber components cannot be obtained when performing finite element simulation calculation on the metal rubber. Step 1 of the present invention: use different numerical simulation models to accurately describe the different compression deformation stages of metal rubber; Step 2: use the obtained metal rubber constitutive relationship to establish a metal rubber component model through finite element simulation software; Step 3: Research components The influence law of the structure size on the metal rubber. Based on the mechanical properties of solid metal-rubber samples, the orthotropic damping material model and the multiple linear kinematic strengthening model in the ANASYS software database were used to describe the deformation process of metal-rubber samples. The structural design of metal rubber is carried out, and the influence of structural size on the mechanical properties of components is analyzed. The invention is used in the design of metal rubber components.

Description

technical field [0001] The invention relates to a design method, in particular to a design method of metal rubber components, in particular to a structural design method based on ANASYS finite element software analysis. Background technique [0002] Rubber materials have good elastic damping performance, anti-corrosion aging performance and long service life at room temperature, and have been widely used in the field of construction machinery as vibration reduction, noise reduction and sealing materials. However, under low temperature conditions, rubber materials show many disadvantages, such as increased hardness and modulus when the temperature is lowered, easy aging in harsh marine environments, and shorter service life in alternating high and low temperatures. Metal rubber is a functional structural material developed to address these deficiencies. [0003] Metallic rubber is a homogeneous porous material that is made of metal wire as a raw material, wound into a spring...
