Title:
WINDSHIELD GLASS PANE SUPPORT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/129286
Kind Code:
A1
Abstract:
Disclosed is a windshield glass pane support structure provided with a windshield glass pane (1); a lower end support member (3) which extends in the vehicle width direction, and supports the lower end of the windshield glass pane (1); and a dynamic damper (7) which is provided at a location that constitutes a resonant vibration antinode, in the vehicle width direction, of the lower end support member (3) in a state where both of the vehicle-widthwise ends of the windshield glass pane (1) constitute resonant vibration nodes. The dynamic damper (7) is an additional vibration system having an additional spring and an additional mass, whereas a main vibration system is such that the glass support stiffness based on the end support member (3) forms the basis of a main spring, and that the windshield glass pane (1) constitutes a main mass. Furthermore, a resonant vibration frequency of the dynamic damper (7) is set in a frequency band where the additional mass vibrates in a phase reverse to the vibration phase wherein the lower end of the windshield glass pane (1) vibrates in a vehicle longitudinal resonant vibration mode generated by a vibration excitation input.
