【摘要】：本文以河北洁神新能源有限公司正在研发的一款纯电动公交客车为研究对象,对其驾驶室进行人机工程学的设计。应用CATIA V5 R20对客车驾驶室进行三维建模的设计,利用CATIA V5中的人机工程模块对客车驾驶室进行人机工程的校核,完成了对驾驶室的基本设计及满足法规要求,应用模糊数学对驾驶室进行层次及重要性的分析,确定了各指标的权重系数,并且应用VC++对纯电动公交客车建立了人机工程的评价系统。具体研究内容有如下几方面:一、客车驾驶室三维模型的设计。参考国家法规标准GB和SAE的有关要求,在CATIA软件中应用创成式曲面设计和零部件设计模块中完成对驾驶室座椅、转向盘、仪表板的设计工作。二、客车驾驶室的人机工程学校核。在设计出的纯电动公交客车模型中,对公交客车的驾驶室进行有关人机工程的校核,其中包括坐姿舒适性校核,视野性校核,空间与可触及性分析与校核等。三、权重系数的确定。应用模糊数学中的层次分析法对客车驾驶室中列出有关人机工程学的影响因素,共分为3个层次,23个评价因素,并为各评价因素确定相应的评价等级;构造驾驶室评价因素的判断矩阵,运用和法计算获得驾驶室评价因素的权重系数。四、建立人机工程评估系统。根据应用模糊数学计算出的权重系数,运用VC++建立纯电动客车驾驶室的综合评价系统。根据评价系统中得出的评价结果,确认其是否符合人机工程学的要求。
[Abstract]:In this paper, a pure electric bus is researched and developed by Hebei Jiesen New Energy Co., Ltd. The ergonomics design of its cab is carried out. Using CATIA V5R20 to design the three dimensional model of the cab of the bus, the ergonomics module of CATIA V5 is used to check the cab of the bus, and the basic design of the cab and the requirements of the regulations are fulfilled. Using fuzzy mathematics to analyze the hierarchy and importance of cab, the weight coefficient of each index is determined, and the ergonomics evaluation system of pure electric bus is established by using VC. The specific research contents are as follows: 1. The design of three-dimensional model of bus cab. According to the requirements of GB and SAE, the design of cab seat, steering wheel and instrument panel is completed in the module of creating curved surface and parts design in CATIA software. Second, the school of ergonomics in the cab of the bus. In the design of the pure electric bus model, the ergonomics of the cab of the bus are checked, including sitting comfort check, visual field check, space and accessibility analysis and check, etc. Third, the determination of weight coefficient. This paper applies the analytic hierarchy process (AHP) in fuzzy mathematics to list the influencing factors of ergonomics in the cab of passenger cars. The factors are divided into 3 levels and 23 evaluation factors, and the corresponding evaluation grades are determined for each evaluation factor. The judgment matrix of cab evaluation factors is constructed, and the weight coefficients of cab evaluation factors are calculated by sum method. Fourth, the establishment of ergonomics evaluation system. According to the weight coefficient calculated by fuzzy mathematics, the comprehensive evaluation system of cab of pure electric passenger car is established by using VC. According to the evaluation results obtained from the evaluation system, confirm whether it meets the requirements of ergonomics.
