The purpose of the cab interior design is to eliminate indoor sound absorption reverberant sound-absorbing material, the higher absorption coefficient Jinan heavy truck cab assembly, the greater the sound absorption area, eliminating the reverberant sound of the car better. Delong cab cab interior acoustics package primarily for roof sidewall material and carpet materials, common roof sidewall trim for hemp fiber, are porous sound-absorbing material, the main role is to remove the car reverberant by increasing the thickness, porosity can be increased to improve the absorption coefficient can also be attached to a certain thickness of the back cover of the local position auxiliary sound-absorbing cotton blankets. In addition to considering the car interiors sound-absorbing properties of the material itself, outside the Chinese heavy truck cab, when the material is disposed in the key hole joints, splices to do the transition sealed China's heavy truck cab assembly, and try to ensure that materials and the inner wall can fit tightly. Engine heat pad attached to cover the floor, insulated glass mat material asbestos, felt material, loose materials such as cotton, its main role is to cut off the engine surface heat transfer to the cab, while both surface radiation absorption isolate engine sound effects . Taking into account environmental issues, engine insulation glass mat should abandon the use of some asbestos materials. Heavy cab development goals: (1) economic objectives control heavy truck cab, 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, 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.
