Teaching platform based on product assembly sequence model facing to virtual disassembly and assembly

Abstract

The invention relates to a teaching platform based on a product assembly sequence model facing to virtual disassembly and assembly, which comprises a disassembly and assembly model, an input module and a comparison module, wherein the disassembly and assembly model can reflect the correct assembly sequence and disassembly sequence of parts; the input module can acquire the actual disassembly and assembly sequence input by a user; and the comparison module compares the actual disassembly and assembly sequence with the disassembly and assembly module and recognizes whether the actual disassembly and assembly sequence is correct. The construction of the disassembly and assembly model comprises the following steps of: acquiring the actual assembly sequence and disassembly sequence of the product parts, and respectively establishing an assembly sequence diagram corresponding to the assembly sequence and a disassembly sequence diagram corresponding to the disassembly sequence; respectively converting the assembly sequence diagram and the disassembly sequence diagram into computer-recognizable data structures; and forming a disassembly model from the data structures. The teaching platform has the advantages of expressing the layer relationship between the assembly sequences and inspecting the reasonableness and correctness of the disassembly sequence made by a user in a disassembly and assembly experiment.

Description

technical field [0001] The invention relates to a virtual disassembly-oriented teaching platform, in particular to a teaching platform based on a virtual disassembly-oriented product assembly sequence model. Background technique [0002] In the mid-1990s, the emergence of virtual product development (VPD) technology has aroused extensive attention of researchers. Virtual assembly is one of its core technologies. How to use the virtual environment to plan the assembly sequence and assembly path of components, and to verify and evaluate the results of assembly planning is one of the research contents of virtual assembly. The generation methods of assembly sequences are mainly divided into three categories: [0003] split method. That is, the method of changing assembly into disassembly, and the assembly process is regarded as the reverse process of disassembly. According to the matching relationship between the parts in the assembly model, Sanderson et al. defined a cut-se...

Problems solved by technology

[0007] In order to overcome the shortcomings of the existing technology that cannot express the hierarchical relationship between the assembly sequences and cannot check whether the disassembly sequence made by the user in the disassembly experiment is reasonable and correct, the present invention provides a method that can express the relationship between the assembly sequences. A teaching platform based on the virtual disassembly-oriented product assembly sequence model that can test the rationality and correctness of the disassembly sequence made by the user in the disassembly experiment
