Computer aided design method and cad system for cutting head of cantilever roadheader

Abstract

The invention discloses a computer-aided design method for a cantilever-type heading machine cutting head and a CAD (computer-aided design) system of the cantilever-type heading machine. Based on Visual C++ 2012, ANSYS14.5 is subjected to secondary development by the computer-aided design method which comprises following modules: a parameter input module, a parametric modeling module, a parametric analysis module, a parametric result displaying module, a performance evaluation module and an optimization and adjustment module; the computer-aided design method includes that a designer enters cutting head design parameters, cutting head condition parameters and coal and rock characteristic parameters, a system can automatically complete modeling and finite element analysis processes, and feedback analysis result files for the designer to perform optimization and adjustment of design parameters. Design of the cantilever-type cutting head under different coal and rock geological conditions and cutting conditions can be realized; performance of the cutting head can be predicted by simulating a cutting process by the aid of the finite element analysis, so that structure optimization of the cutting head can be realized according to analysis results, and level of cutting head design is greatly improved.

Description

technical field [0001] The invention relates to a computer-aided design method and a CAD system; in particular, it relates to a computer-aided design method for a cutting head of a cantilever-type roadheader and a CAD system for the cutting head of a cantilever-type roadheader. Background technique [0002] The cutting head of the cantilever roadheader is a key component for coal and rock cutting, and its performance determines the working efficiency and service life of the whole machine. The cutting head is subjected to a large impact load during the working process, and each pick on the cutting head is subjected to different forces, which will cause the weak pick to reach the maximum static strength and be destroyed; and the fluctuation of the load can cause the whole machine Vibration, which leads to fatigue damage of some components, these factors will affect the service life of the entire roadheader. [0003] Different coal and rock geological conditions have an import...

AI Technical Summary

Problems solved by technology

The traditional cutting head design process is based on the given coal and rock parameters and cutting head working condition parameters, etc., relying on the experience of the designer, referring to the existing model for analogy design, lack of sufficient theoretical support, resulting in a relatively low level of overall design. Low, the designed cutting head is also difficult to adapt to the working conditions
