Description

technical field [0001] The invention belongs to the technical field of wheel optimization design, and in particular relates to a method for optimal design of mechanical elastic wheel structure parameters. Background technique [0002] The structural characteristics of mechanical elastic wheels and their load-bearing methods determine that when different wheel structural parameters, elastic structural parameters and hinge group structural parameters are used in combination, their mechanical properties will also change accordingly. The section width and height of the wheel, the section width and height of the elastic ring, the length, width and number of the hinge group have an important influence on the mechanical characteristics of the wheel. At present, the structural parameters in the design process of the mechanical elastic wheel are only based on simple theoretical calculations plus The test adjustment of the prototype has the disadvantages of low precision and poor perf...
