Abstract

A windshield glass support structure includes a windshield glass (1), a lower end support member (3) supporting a lower end portion of the windshield glass, and a dynamic damper (7) provided at a position corresponding to a resonance antinode of the lower end support member. The dynamic damper is an additional vibration system including an additional spring and an additional mass with respect to a main vibration system in which a glass support rigidity of the lower end support member is a main spring and the windshield glass is a main mass. A resonance frequency of the dynamic damper is set in a frequency band in which the additional mass vibrates in an antiphase with respect to a vibration phase in which the lower end portion of the windshield glass vibrates in a resonance node in a front-back direction of the vehicle caused by a vibration input.

Claims4

Dependent claims

A windshield glass support structure, comprising:

a lower end support member extending in a width direction of a vehicle to support a lower end portion of a windshield glass, and having a curved shape formed in such a manner that a center portion projects toward a front side of the vehicle and both side portions extend toward a back side of the vehicle,
wherein the lower end support member includes a linear portion formed in such a manner that a middle curved portion of the lower end support member is straightened in the width direction, and a flat plate portion continuously extending downward from the linear portion, and
a resonance frequency of the linear portion and the flat plate portion is set in a frequency band in which the flat plate portion vibrates in an antiphase with respect to a vibration phase in which the lower end portion of the windshield glass vibrates in a resonance mode in a front-back direction of the vehicle caused by a vibration input.
