Delong cab body insulation measures The panel low frequency sound insulation material stiffness and damping properties of the relevant heavy truck cab pictures, sound insulation performance of the IF law follow the quality, the greater the surface density, the greater the amount of noise, and therefore meet the requirements under the control of body weight heavy truck cab exterior parts, an appropriate increase in the thickness of the door window glass, optimizing allocation body panels at key locations (floor, cowl-based) thickness can effectively improve the sound insulation properties of the body as a whole. The main role is to isolate the floor carpet incoming noise Chinese heavy steam cab image, the choice of materials which are more numerous, there is a felt composite film + PV, PV film + foamed material, the carbon fiber composite material + cotton blankets, etc. Tests show that the lower increase areal density cotton felt or mat can effectively isolate the floor apertures incoming Chinese heavy truck cab pictures, heavy truck cab, Jinan Yiu Cheung Yiu Cheung provided by Jinan Trading Company Jinan Yiu Cheung Trading Company (www.jinanyaoxiang.com) strong, credible, in Shandong Jinan engine assembly industry has accumulated a large number of loyal customers.
