Heavy cab development goals: (1) economic objectives control, cost, schedule and user requirements (demand). (2) target control technology, technical specifications, design quality, process design quality, manufacturing quality. To achieve these objectives, in the design of modern design methods should be employed Shandong heavy truck cab, 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, structural dynamic analysis, safety 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; application of computational fluid dynamics simulation analysis of the status of vehicle wind hole test; the application of virtual reality technology to heat the cab comfort, sitting comfort, ease of manipulation, vision and so on; and metal forming analysis applications. Heavy truck cab BIW main production processes for the production of stamping process using cab BIW sub-assemblies of sheet metal parts, and then use the various pieces of sheet metal welding process will link up to form a floor assembly, left and right side panel assembly, front wall assembly, rear surround assembly, assembly, and other six functional roof assembly, final assembly and then use the six functional robot welding connection to cab BIW assembly. Currently a heavy truck cab BIW about 150 to 200 sheetmetal heavy truck cab, spot welds connecting the sheet metal around 4000 to 6000, and now the sheetmetal to large-scale, holistic development Jinan heavy truck cab assembly, such as whole roof outer plate, the whole front wall outer panel, the whole rear wall outer panel, the whole left side wall outer panel, etc., which formed part of the basic pressure in more than 1,000 tons, for stamping dies manufacturing precision, strength, stiffness and other indicators put forward higher requirements. 4000 to 6000 will be so much sheetmetal spot in strict accordance with a certain relative position of the connection of the welding fixture positioning system and clamping system requirements are higher.
