Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings.

[0023] The invention provides a method for optimizing an aircraft assembly path based on human biological characteristics. To study the influence of workers' biomechanical characteristics on the aircraft assembly path in aircraft assembly, because the ergonomics research system considering human-to-machine and environmental factors is not perfect and systematic, there is a lack of evaluation basis for assembly workers' posture and workers' stress state Do your research. Based on the influence of biomechanical characteristics on the aircraft assembly process, a reasonable evaluation criterion and evaluation scheme are established. From the perspective of aircraft assembly work efficiency and safety protection, the factors affecting aircraft assembly and workers'...

Abstract

The invention discloses a method for optimizing an aircraft assembly path based on human biological characteristics, and belongs to the technical field of aircraft assembly. The optimization method includes establishing an assembly model; constructing a virtual human body model; establishing a fuzzy comprehensive evaluation model based on a time task based on a fuzzy comprehensive evaluation algorithm; establishing a state balance equation according to the overall force of the assembly worker; Dynamics modeling of lower limbs of aircraft assembly workers; synthesis of various models to obtain an optimized assembly path. Based on aircraft digital assembly, the invention optimizes aircraft assembly path through virtual human body modeling to study worker's posture and human biological characteristics in the assembly process, so as to improve aircraft assembly efficiency and protect workers' health.

Description

technical field [0001] The invention provides an optimization method of an aircraft assembly path based on human biological characteristics, relates to the realization of an aircraft assembly path based on human biological characteristics, and belongs to the technical field of aircraft assembly. Background technique [0002] The assembly and installation of aircraft is the core task in the aircraft manufacturing process. Aircraft assembly technology is not only very difficult in the field of aviation manufacturing, but also involves various knowledge and technologies. The quality and efficiency of assembly will directly affect the manufacturing cost and production cycle of aircraft. . Therefore, aircraft assembly technology is the key and core technology in the entire aircraft manufacturing process. Compared with the traditional machinery manufacturing industry, the aircraft assembly process is more complicated. Not only are there a variety of parts and a large number, but ...
