[Abstract]:The thesis is selected from the design of the new cab of GC6t hydraulic excavator in a certain enterprise. The old cab of GC series can not meet the requirements of comfort, sealing and safety of the cab, and the new cab has been designed in combination with the development plan of updating the model. At the same time, the verification and improvement of ergonomics ROPS (anti-roll safety) and reducing noise comfort are carried out by digital method. Finally, the prototype is made and evaluated. The newly designed cab prototype has got good evaluation results and has been produced in mass production. The paper is divided into three parts. In the first part, this paper analyzes the layout and structural shortcomings of the old cab, such as the location of the monitor is too low, the human eye observation is not convenient, the interior decoration is old, the arrangement of the control device is unreasonable, etc. On this basis, the basic theory and design criterion of ergonomics are studied, the static and dynamic parameters of human body size are analyzed, and the application of advanced digital simulation design in ergonomics is investigated. The research method and train of thought of this design are determined. Then, the second part of this paper based on Pro/Engineer modeling and analysis software to establish the cab structure and internal layout model, in the layout design process to ensure the cab visual field, internal space. The layout of the control device meets the requirements of ergonomics, and the ergonomics analysis and confirmation of the operating space, the driver's posture, the comfort during the operation and the range of visual field during the operation are carried out after the layout design is completed. These analysis and validation theories or reference criteria include: design H point determination method, seat layout and seat height, hand extension and interface and comfort control range, instrumentation layout, control device layout, size of operating space, Manipulative force and body joint angle, eye ellipse position, 95 th percentile human visual field range. In addition, this paper also designs the new cab interior design, color collocation design, safety design and ROPS finite element analysis, ventilation, refrigeration and heating design, The vibration reduction and noise reduction, modal analysis of the panel and other humanized design are briefly discussed, and the rationality of the design is verified. In the third part, the fuzzy comprehensive evaluation method is applied to evaluate the shape and comfort of the new cab, and the degree of satisfaction of the evaluator to the new cab is calculated by weighted evaluation and score. Through the process of cab design and prototype evaluation, this paper summarizes the ergonomics principles and design rules that need to be satisfied in the design process of excavator cab, and puts forward the digital design and verification method of cab design. The standard method of cab design in the future is determined, and the evaluation method of cab comfort degree is also put forward. According to this method, the prototype of the new cab is evaluated and passed, and the new cab smoothly enters the mass production stage.
