| My thesis reference to the subject of the basic principles of ergonomics and its application in the automotive industry, through the analysis of ergonomics in the cab of construction layout of the practical application of body issues, synthesize foreign and Chinese auto industry design standards for the industry standard, combined with the size of the Chinese characteristics of the human body to CATIA V5 software platform, using the parts module simulate the cab, while the module was simulated using ergonomic evaluation of the 5th percentile with the 95th percentile and the number of the human numbers, the driver Members of the hands and feet but it encompasses the eligibility and evaluation of seat comfort, supporting the secondary development of Visual Basic software, developed for construction machinery human evaluation of thestate-owned enterprise internal check system.In this paper, as the research object crane cab, the cab existing problems such as interface match irrational old, seating comfortless, narrow operation space and noise environment control wellness . Through split the actual beacon vehicle's and measure internal component's value, besides owing to the calculation formula of Auto Industry, let the measurement values substitute the formula and calculate it, then get the initial data of cab and definite pilot's seat's place depth, the place width, the place higher value. On the basis of comfort degrees ascertain evaluation data. Operator the ergonomics's size of cabin component and according to formula of the plane of pedals then calculate the foot pedal angle, through the company's coordinate axes drawn fix the H point, the root supports the best plane sphere of action computation goes well the arm as well as foot's department best sphere of action, obtains the data has established the corresponding appraisal weight, has provided the science basis for cab's design. The crane cab belongs to N kind in the domestic automobile profession minute, the design main reference truck's cab, therefore appraises the standard mainly refers to "Truck Pilot Position of operation Size" as well as the SAE related standard. The paper mainly uses the automation to carry on the re-development using the connection great way, carries on the procedure using the VB language tool the edition, the CATIA man-machine module provided the detailed human body database to be possible to carry on very good docking with the re-development data. Defines the appraisal project editor secondary appraisal menu in VB, meanwhile define menu meanwhile define menu in CATIA and records great integrates in the software to go to and VB edition appraisal menu docking. After inducting the different hundred ranks the manikin, enters the development in the evaluation system to carry on the corresponding evaluation program, appraises using the digit manikin simulation operating process to the cab. Then enter to evaluation system go on assessment process, all the process of evaluation under the virtual environment, when the evaluation system give the degree of comfort numerical value, the designer could based on the suggestion of computer and adjust the design,it make the project perfect and truncated the time of model machine to checking the design, saving the business costs.This topic has the very good virtual value to the enterprise, from now on the project special purpose vehicle no matter the modification design or finished Automobile development may use this system, it will save production cycle effectively, and speed up the product the renewal, the enterprise will have the design independent property right.The paper discussed the importance of man-machine appraisal in the earlier design period The union overseas cab's design way has developed the man-machine engineering in the engineering machinery cab's design the practical application scope and the fundamental research, advocated that the design pleasant, comfortableness, increased our country engineering machinery's market competitiveness. |
