NOISE-AND-VIBRATION DAMPING UNIT OF VEHICLE BODY PANEL Russian patent published in 2000 - IPC

FIELD: transport engineering; cab and body vibration damping members. SUBSTANCE: unit has external face panel 1 connected through gasket 3 made of viscoelastic damping material with stiffener 2 made in form of bar with corrugation section. Novelty is that material of gasket 3 features definite physical and mechanical properties. Gasket can be made with discrete structure, and summary length of its components in this case should be not less than 30% of total length of stiffener 2. Gasket 3 can be arranged between base of corrugation of stiffener 2 and plane of face panel 1. Gasket 3 can be arranged also between top of corrugation of stiffener 2 and plane of face panel 1. EFFECT: enhanced efficiency of damping of vibrations of face panels in vehicle body cab. 4 cl, 13 dwg
