Cab Ergonomics Development And Research Of Mining Dump Truck

Large tonnage mining dump truck mainly operation in the mine,theoperation environment is evil, and this kind of car is different from generalroad vehicles, which the cab is placed on a platform, the height from theground is high, and the driver operate it frequently, so it is necessary todevelop and research the cab ergonomics. To improve the performance of thevehicle ergonomics, design and development phase in the cab fully considerergonomic factors, be reasonable arrangement designed to improve the driver’sride, handling comfort, fully meet the vision, can be stretched and otherrequirements. In this paper, a bottom-up cab design ideas, starting from thedriver, the cab interior layout design conducted to determine the overall sizeof the cab. First, determine the location and pedal hard point parameters,mainly riding plane angle is determined, on this basis, the analysis of thelocation of the H point. This article is based on Chinese human dimension, sothat the body joints in a comfortable position, analyzed the H-point area. Then,to further secure the seat angle, resulting Comfort Curve H-point, and with theappropriate SAE line were analyzed. According to the H-point regionpreviously identified, selected the appropriate H-point, determined eyeposition and shape of the ellipse, oval shape and position of the eyedetermines the position of the driver’s line of sight. On the basis of the eyeellipse, the use of the front view and the steering wheel cover the horizons fordetermining the design of dashboard and layout design of the dashboardcomponents. Then, to complete the design of hands and feet Controllingdevices, and driver work space. Finally, the arrangement of the cab before thetext-based3D model to build inside the cab, the introduction of simulationsoftware RAMSIS, combined with the general arrangement module of UG, usea small amount of CAD data early in the design for a lot of performanceanalysis, a comprehensive check the attitude of the dump truck cab comfort,hands and feet can be stretched and vision and so on.
