Three-dimensional assembly process teaching method and system based on ergonomic simulation analysis

Abstract

The invention relates to a three-dimensional assembly process teaching method and system based on ergonomic simulation analysis. MBD model data are formed by constructing an assembly process proceduredisplay assembly database, and assembly sequence and assembly path data are formed through ergonomic simulation analysis, and an assembly process animation is generated through a mechanism kinematicsalgorithm, so that three-dimensional assembly visualization is realized; according to the three-dimensional assembly process teaching system and method, assembly process optimization and fine visualcontrol are achieved, the on-site assembly mode is effectively improved, the technical bottleneck problem that demonstrativity and teaching performance of an existing three-dimensional assembly process teaching system and method do not conform to actual working conditions can be effectively solved, and the three-dimensional assembly process teaching system and method have good use value.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly technology, in particular to a three-dimensional assembly technology teaching system and method based on ergonomics simulation analysis. Background technique [0002] As is known, wheeled tractors are short for wheeled tractors. At present, the workshop assembly process of wheeled products is in a critical stage from traditional technology to digital technology. The traditional technology mainly relies on technical language, supplemented by a certain two-dimensional assembly schematic diagram , in terms of content and form, assembly workers need certain requirements for the conversion and absorption capacity of two-dimensional drawings, which must be completed by experienced process design and on-site assembly personnel. It takes a long time to accept new products and new processes, and often requires a lot of work. Repeated work; at the same time, its level of refinement, comprehensib...

Problems solved by technology

[0004] 1. The existing 3D assembly process teaching system and method only use MBD (Model Based Definition, that is, model-based engineering definition, which is a method body that uses an integrated 3D solid model to fully express product definition information) technology The assembly animation comes from the assembly process generated by the assembly sequence of the 3D modeling software, resulting in differences between the assembly path and the actual working conditions, which only have a schematic function;

[0005] 2. The existing 3D assembly process teaching system and method do not analyze the assembly process based on ergonomics, and lack the optimization of the assembly process, so the guidance for the process is not strong
