Heavy cab development goals: (1) economic objectives control, cost, schedule and user requirements (demand). (2) technical target control heavy truck cab exterior parts, technical specifications, design quality, process design quality, manufacturing quality. To achieve these objectives, in the design of modern design methods should be employed, through the implementation of the following to complete the objectives and tasks. Application of computer-aided verification techniques keel framework and structure of the cab BIW static analysis, dynamic analysis of the structure, security analysis and fatigue analysis; application of computer-aided modeling and digital prototyping solutions to create the shape of the cab, and the cab shell and exterior structure diagram; Computational fluid dynamics simulation of wind tunnel test vehicle status; application virtualization reality technology to heat the cab comfort, sitting comfort, ease of manipulation, vision etc; and metal forming analysis applications. Delong cab usability concerns. Delong cab usability aspects include: HMI elements reasonable, readable interface and control feel good. Only by anthropometry and biomechanics knowledge and data, in order to ensure the cab environment suitable for the physical and psychological characteristics of the human body, to ensure a healthy posture drivers working heavy truck cab, making people work both efficiently complete ' they feel comfortable and will not produce fatigue. Cab seat design parameters should meet the "seat - settee" angle of 92 degrees, 7 degrees inclination seat after China's heavy truck cab, seat height 43-50cm, 48-52cm deep seat CNHTC Jinan cab, seat depth of 40-42cm, backrest height 45-50cm, influencing factors, including the degree of visual dashboard perspective and horizon, dashboard own size, display size proportions and shape information and graphics, digital arrangement, display color and other factors. Should be simple, eye-catching as the main design language, avoiding complicated graphics.
