Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0020] like figure 1 The interactive virtual disassembly teaching method shown, which includes the following steps:

[0021] Step S1: Collect teaching model parameters and assembly relationship information of the disassembly teaching object, and use the collected teaching model parameters and assembly relationship information to construct an overall physical model of the disassembly teaching object in the modeling software, and disassemble the teaching object overall physical model. During the construction of the model, the spatial constraint relationship between the components of each disassembled teaching object in the overall physical model is obtained; the model parameters and assembly relationship information include the shape of the teaching model components, the size of the teaching model components, and the avoidance of the co...

Abstract

The invention discloses an interactive virtual disassembly teaching method, comprising the following steps: S1: importing the collected teaching model parameters and assembly relationship information into preset modeling software, constructing an overall physical model of the disassembly teaching object, and disassembling During the construction of the overall physical model of the teaching object, the spatial constraint relationship between the components of each dismantling teaching object in the overall physical model is obtained; S2: The Petri network logic model of the dismantling teaching object is obtained; S3: The components are combined in the 3D software development engine. Constraint relationship and component disassembly priority are introduced into particle swarm algorithm to obtain component disassembly sequence; S4: In the 3D software development engine, use the component constraint relationship, component disassembly priority, and component disassembly sequence to make various components The required disassembly teaching object parts disassembly mode, and a virtual interactive platform for disassembling teaching objects is built. The invention realizes the development of a virtual disassembly system with multiple interactive modes.

Description

technical field [0001] The invention relates to the technical field of virtual teaching, in particular to an interactive virtual disassembly teaching method and system. Background technique [0002] The traditional disassembly teaching mode has some problems such as large size and complex structure, poor safety and high cost when used for disassembly teaching, and it is difficult to disassemble in kind; most of the current disassembly teaching methods use pictures and video teaching, lack of In practice, some complex structures are difficult to understand, requiring users to imagine the space, and the learning efficiency is low; due to site constraints, in some special working environments, operators cannot complete the disassembly of parts in actual work. The existing problems urgently need a modern disassembly teaching method to solve. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an interactive virtual disassembly teaching method ...
