Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings.

[0023] The invention provides a method for optimizing an aircraft assembly route based on human biological characteristics. To study the influence of the biomechanical characteristics of workers on the aircraft assembly path in aircraft assembly. Due to the incomplete and systematic ergonomics research system considering human-to-machine and environmental influence factors, there is a lack of evaluation basis for the posture of the assembler and the force state Start research. Based on the influence of biomechanical characteristics on the aircraft assembly process, a reasonable evaluation criterion and evaluation plan are established. From the perspective of aircraft assembly ergonomics and safety protection, the factors affecting aircraft assembly and worker h...

Abstract

The invention discloses an aircraft assembly path optimization method based on human body biological characteristics, and belongs to the technical field of aircraft assembly. The optimization method comprises the following steps: establishing an assembly model; constructing a virtual human body model; establishing a fuzzy comprehensive evaluation model based on the time task based on a fuzzy comprehensive evaluation algorithm; establishing a state balance equation according to the overall stress condition of the assembly worker; carrying out dynamic modeling on upper limbs of aircraft assemblers; carrying out dynamic modeling on the lower limbs of aircraft assemblers; and integrating the models to obtain an optimized assembly path. On the basis of aircraft digital assembly, the postures ofworkers, human body biological characteristics and the like in the assembly process are studied and analyzed through virtual human body modeling, the aircraft assembly path is optimized, and the purposes of improving the aircraft assembly efficiency and protecting the health of the workers are achieved.

Description

Technical field [0001] The invention provides a method for optimizing an aircraft assembly path based on human biological characteristics, which 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] Aircraft assembly and installation are the core tasks in the aircraft manufacturing process. Aircraft assembly technology is not only difficult in the aviation manufacturing field, but also involves many aspects of knowledge and technology. The assembly quality and efficiency will directly affect the manufacturing cost and production cycle of the 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 is there a wide variety of parts and a large number, but als...
