Delong cab body insulation measures. Panel low frequency sound insulation material stiffness and damping properties of heavy truck cab exterior parts, IF acoustic performance related heavy truck cab following the mass law, the greater the surface density, the greater the amount of noise in Shandong heavy truck cab, and therefore meet the body Under the weight of the control requirements, an appropriate increase in the thickness of the door windows, siding optimization (floor, cowl-based) of thickness distribution of the body at key locations can effectively improve overall vehicle noise performance. The main role of the carpet is to isolate the incoming noise floor, the choice of materials is more variety, there are blankets composite film + PV, PV film + foam, carbon fiber composite materials + cotton blankets. Tests show that the underlying felt or cotton blankets increase areal density can effectively isolate the purpose floor apertures incoming sound absorption cab interior design is to eliminate indoor reverberant sound, sound-absorbing material, the higher the absorption coefficient, the greater the sound absorption area heavy truck cab assembly, 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 absorption properties of the material itself, but when the material is disposed in the key hole joints, splices to do the transition seal the deal, and try to ensure that the material 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.
