Since the number of parts is reduced and the operation is easy, cost reduction can be achieved, and rigidity is sufficiently reinforced to effectively control the vibration of the roof panel, thereby significantly reducing interior noise.
Description
본 발명은 자동차 실내소음 저감을 위한 루프패널 강성보강법에 관한 것으로, 특히 루프패널에서 루프레일을 제외한 전면에 보강멤버 대신에 제진성능이 높은 아스팔트 패드형 제진재를 부착함으로서 루프패널의 진동을 억제하여 차실내소음을 저감시킬 수 있는 루프패널의 강성보강법에 관한 것이다.The present invention relates to a roof panel stiffness reinforcement method for reducing interior noise of an automobile. In particular, by attaching an asphalt pad type vibration damper having high vibration damping performance to the front surface of the roof panel except for the roof rail, the vibration of the roof panel is suppressed. The present invention relates to a stiffness reinforcement method of a roof panel that can reduce interior noise.
종래의 자동차 루프패널(1)은 도 2에 도시한 바와 같이 면적이 1 × 1 ㎡ 내외의 크기의 평판으로 되어 있으므로 강성을 강화하기 위하여 루프패널(1)의 횡방향으로 2개 이상의 보강멤버(2)로 보강하게 된다. 그러나 루프패널(1)면이 얇아서 보강멤버(2)를 고정시 용접이 불가능하여 실러로 부착하기 때문에 작업자가 상당히 신경을 써서 붙이지 않으면 제대로 부착되지 않는다. 그러므로 루프패널(1)과 보강멤버(2) 사이 간극에서 발생하는 진동으로 인하여 차실내의 소음이 심한 문제점이 있었다. 도면부호 3은 트림이다.As the conventional vehicle roof panel 1 is a flat plate having an area of about 1 × 1 m 2 as shown in FIG. 2, two or more reinforcing members in the transverse direction of the roof panel 1 are provided to enhance rigidity. 2) will be reinforced. However, because the roof panel 1 is thin, the welding of the reinforcing member 2 is impossible when the reinforcing member 2 is fixed, and thus it is attached by a sealer. Therefore, due to the vibration generated in the gap between the roof panel (1) and the reinforcing member (2) there was a serious problem in the interior of the vehicle. Reference numeral 3 is a trim.
따라서, 본 발명은 상기한 문제점을 감안하여 이루어진 것으로, 루프레일을 제외한 루프패널 전면에 기존의 보강멤버 대신에 제진성능이 우수한 제진재를 부착한 것으로서 부품수가 줄어 들어 작업이 쉬고 이로 인하여 코스트를 낮출 수 있는 동시에 루프패널의 강성을 보강하여 진동을 효과적으로 억제하므로서 차실내의 소음을 효과적으로 저감시킬 수 있는 루프패널을 제공하는 것을 과제로 한다.Accordingly, the present invention has been made in view of the above-mentioned problems. Instead of the existing reinforcing members, a vibration damping material having excellent vibration damping performance is attached to the front of the roof panel except for the roof rail, thereby reducing the number of parts and thus reducing the cost. The present invention also aims to provide a roof panel that can effectively reduce noise in a vehicle by effectively suppressing vibration by reinforcing the rigidity of the roof panel.

상기한 과제를 달성하기 위한 본 발명의 구성 및 작용을 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Referring to the configuration and operation of the present invention for achieving the above object in detail based on the accompanying drawings as follows.
도 3에 도시한 바와 같이, 다수개의 보강멤버(2)의 양끝단이 고정된 루프레일(도시생략)이 용접되어 있는 통상의 루프패널(1)에 있어서, 상기 루프레일을 제외한 루프패널(1) 전면에 상기의 보강멤버(2) 대신에 아스팔트 패드형 제진재(2')를 부착한 것이 특징이다. 도면중 미설명부호 3은 트림이다.As shown in Fig. 3, in a conventional roof panel 1 in which loop rails (not shown) in which both ends of a plurality of reinforcing members 2 are fixed are welded, the roof panel 1 except for the roof rails 1 is welded. ) As an alternative to the reinforcing member (2) in front of the asphalt pad-type vibration damper (2 ') is characterized. Reference numeral 3 in the drawings is a trim.
상기한 구성에 의하면 루프패널(1)에서 루프레일을 제외한 전면에 제진성능이 우수한 수성 또는 아스팔트 패드형 제진재(2')를 부착하였기 때문에 루프패널(1)의 강성이 충분히 보강되어서 진동을 효과적으로 제어할 수 있다.According to the above configuration, since the water-based or asphalt pad-type vibration damping material 2 'having excellent vibration damping performance is attached to the entire surface of the roof panel 1 except for the roof rail, the rigidity of the roof panel 1 is sufficiently reinforced to effectively vibrate the vibration. Can be controlled.
또한, 본 발명은 루프패널(1)의 위치가 차실내 승객의 귀위치에 가까이 있어서 다른 부위에서의 대책보다 고주파수(250-600㎐영역)에서 소음저감 효과가 크다. 따라서 도 4에 나타낸 바와 같이 차량가속 주행시 1-2㏈이상의 소음저감 효과가 있음을 알 수 있다.Further, in the present invention, since the position of the roof panel 1 is close to the position of the passenger in the cabin, the noise reduction effect is higher at high frequencies (area of 250 to 600 Hz) than the countermeasure at other parts. Therefore, as shown in Figure 4 it can be seen that there is a noise reduction effect of 1-2㏈ or more during vehicle acceleration driving.
이상과 같이, 본 발명에 의하면 기존의 루프패널에 용접된 루프레일에 양끝단이 고정되어 패널면에 부착된 보강멤버 대신에 루프레일을 제외한 전면에 제진성능이 우수한 수성 또는 아스팔트 패드형 제진재를 부착한 것이기 때문에 부품수가 줄어들고 작업이 용이한 관계로 코스트다운을 도모할 수 있을 뿐만 아니라 강성이 충분히 보강되어 루프패널의 진동을 효과적으로 제어함으로서 차실내 소음을 현저히 저감시킬 수 있는 이점이 있는 것이다.As described above, according to the present invention, both ends are fixed to the roof rail welded to the existing roof panel, and instead of the reinforcing member attached to the panel surface, an aqueous or asphalt pad type vibration damper having excellent vibration damping performance on the entire surface except the roof rail is used. Because it is attached, the number of parts is reduced and the operation is easy, so that not only the cost can be reduced, but also the rigidity is sufficiently reinforced to effectively control the vibration of the roof panel, thereby significantly reducing the interior noise.
