Body panel with vibration damping material,vibration damping material coater, and damping material application method

摘要

As a wrist portion (14) of an application robot equipped with a plurality of application nozzles (15a, 15b) moves in a predetermined operation pattern, viscous damping and constraining materials having different properties are simultaneously injected from the application nozzles in such a manner that immediately after the damping material is injected from the preceding application nozzle (15a), as viewed in the moving direction (outline arrow in FIG. 5), and applied to a vehicle body panel (11) as an underlayer material, the constraining material having different property is injected from the succeeding application nozzle (15b), as viewed in the moving direction, and applied as an overlayer material over the underlayer material.
