VEHICLE Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to automobiles, particularly to body members, such as doors of passenger cars or cabs of trucks. Molding in mounted on outer face panel of door. Molding is made of polymeric material. Ratio of Young's moduli E₁ and thickness h₁ of metal face panel and Young's modulus E₃ thickness h₃ molding material is defined by equation . Mechanical oscillatory structure "door face panel - molding" features composite coefficient of losses not less than 0.1. Invention provides vehicle whose door is furnished with set of noise and vibration damping devices acceptable from point of view of weight and cost and features additional sufficient efficiency of vibration damping and weakening of noise radiation of door face panel, firstly in process of shutting the doors and secondly in process of high quality reproduction of musical signals of acoustic systems in car interior. EFFECT: improved characteristics of vehicle body members. 2 cl, 10 dwg
