The purpose of the cab interior design is to eliminate indoor sound absorption reverberant sound-absorbing material, the higher absorption coefficient China's heavy truck cab, sound absorption area is larger Jinan heavy truck cab assembly, eliminating the effect of the more reverberant car Okay. 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 Shandong heavy truck cab, the main role is to eliminate the car within reverberant, by increasing the thickness, increase the porosity can increase the absorption coefficient can also paste the cover on the back of a certain thickness of the local position of the 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. After some light truck cab suspension gantry fracture, fracture automotive parts such engineering applications recurrent problem, some parts may affect fracture vehicle performance and safety. So heavy truck cab now come Fracture analysis refers to the main reason causing the fracture. From the responsibility of view, can be divided Fracture design reasons, material reasons, the process causes the environment (with or aging) and other reasons; from mechanical point of view, the reason is to determine the fracture resistance of the material is too small or too large load power. Different fracture resistance index of different fracture modes of material reasons. Plastic fracture resistance index generally refers to the tensile strength; resistance to brittle fracture toughness index generally refers to the material or fracture toughness; fatigue fracture resistance index generally refers to the fatigue limit fatigue or stress conditions. As designers need to focus on for the fracture problem solving and analysis, the reasons for the difference between the fracture and the development of relevant improvement measures to meet the requirements of the design outline.
