Embodiment Construction

[0024] The content of the present invention will be described below in conjunction with specific embodiments.

[0025] like figure 1 As shown, it is a structural schematic diagram of a method for designing the dynamic characteristics of robot structures based on simulation analysis.

[0026] Include the following steps:

[0027] 1) Use 3D design software to establish a 3D model of the main load-bearing structure of the robot;

[0028] 2) Use the finite element pre-processing software to establish the grid model of the main load-bearing structure of the robot;

[0029] 3) Import the grid model of the structure into the strength analysis software, and at the same time apply the ultimate load and constraint boundary conditions that the structure bears during the actual working process of the robot, and calculate the stress distribution and displacement distribution of the structure;

[0030] 4) Import the grid model of the structure into the dynamic response analysis software,...

Abstract

The invention relates to a simulation analysis based dynamic characteristic design method for robot structures, and belongs to the field of machinery design. According to the method, through three-dimensional modeling, grid modeling, strength analysis, dynamic response analysis, comparison analysis and optimal structure design, the robot structures meeting requirements are designed after multi-iteration. The simulation analysis based dynamic characteristic design method has the advantages that a strength and dynamic characteristic simulation analysis method is combined with the design optimization of the robot structures, defects and redundancies of the design can be exposed accurately in a robot structural design stage, improved structures are guided and designed effectively according to simulation analysis results, and the robot structural design can achieve best optimized results through repeated iterative calculation, so that the situation that robot functional performance may not meet requirements due to the structural design in engineering can be avoided as much as possible, and robots can meet requirements on lightweight structures.
