Description

차량의 차체와 루프를 연결하는 센터 필러 구조{Center pillar structure}Center pillar structure that connects the vehicle body and roof

본 발명은 차량의 차체와 루프를 연결하는 센터 필러 구조에 관한 것이다. 더욱 상세하게는 차량 차체의 외측 부재와 내측 부재로 이루어진 폐 단면 내부에 보강부재 형성에 의해 3개의 내측 폐 단면을 구성함으로써 루프 크러쉬 레지스턴스 시험의 신 법규를 만족할 수 있는 센터 필러의 구조에 관한 것이다.The present invention relates to a center pillar structure for connecting the vehicle body and the roof of the vehicle. More specifically, the present invention relates to a structure of a center pillar capable of satisfying the new law of the loop crush resistance test by forming three inner closed cross sections by forming a reinforcing member in a closed cross section composed of an outer member and an inner member of the vehicle body.

일반적으로, 승용차 개발시 루프의 기본적인 강도를 확보하도록 미연방 자동차 안전법규인 FMVSS 216항목에 루프 크러쉬 레지스턴스 시험(roof crush resistance test)이 있으며, 최근 국내에서도 자동차 안전에 관한 규칙 92조로 적용된 법규이다.In general, in order to secure the basic strength of the loop in the development of a passenger car, a roof crush resistance test is included in the FMVSS 216, the US automobile safety law, and the law has been recently applied as Article 92 of the automobile safety rule in Korea.

상기 시험목적은 FMVSS 216항목을 만족하면서 차량 전복시 승객실의 운전자 및 탑승자의 안정성을 확보하고 루프 사이드와 프론트 필러, 센터 필러의 강성을 확보하기 위한 통상 루프 크러쉬의 시험방법을 채택하고 있다.The purpose of the test is to satisfy the FMVSS 216, and to adopt the normal roof crush test method to secure the stability of the driver and occupant of the passenger compartment when the vehicle is overturned and the rigidity of the roof side, front pillar and center pillar.

다시 말해서, 설계초기단계에서 법규를 만족하고 안전측면에서 승객실의 안 전성을 확보할 수 있는 어퍼 바디(upper body)의 구조를 얻기 위함이다.In other words, it is to obtain the structure of the upper body that satisfies the regulations at the initial stage of the design and secures the safety of the passenger compartment in terms of safety.

상기 법규의 시험방법은 창문을 모두 닫고 도어(door) 또한 잠근 상태에서 차체를 지그(jig)에 고정한다. 다음에 리지드 램(rigid ram)의 길이방향 축이 수평선을 기준으로 하여 전방하부를 향하여 5°기울어지게 설치되면서 그 횡방향 축이 수평선을 기준으로 하여 실외측하부를 향하여 25°기울어지게 설치한다. 시험장치의 아래 부분은 차량과 접하도록 하고, 최초 접촉점 또는 접촉하고 있는 표면의 중심이 시험장치 밑면의 길이방향 중심선상에 있고 그 중심선으로부터 앞쪽으로 10 인치가 되도록 한다.In the test method of the regulation, the vehicle body is fixed to the jig while all windows are closed and the door is also locked. Next, the longitudinal axis of the rigid ram is installed at an angle of 5 ° toward the front lower part with respect to the horizontal line, and the horizontal axis is installed at an angle of 25 ° toward the outdoor side lower part with respect to the horizontal line. The lower part of the test apparatus is in contact with the vehicle and the initial contact point or center of the contacting surface is on the longitudinal centerline of the bottom of the test apparatus and is 10 inches forward from the centerline.

이와 같이 설치한 상태에서 리지드 램을 수직하방으로 1.5 인치/초의 속도로 하중을 가하되 공차중량의 1.5배, 또는 5000파운드 중, 낮은 하중에 도달할 때까지 하중을 가하며 120초 이내에 시험을 완료한다. 이런 단계에 의하여, 시험장치가 움직인 거리, 즉 시험장치의 밑면이 원래 위치에서 위에 명시된 값에 도달했을 때 위치간의 거리를 측정한다.Load the rigid ram at a rate of 1.5 inches / sec vertically in this manner, but complete the test within 120 seconds with a load of 1.5 times the tolerance weight, or 5000 pounds, until the lowest load is reached. . By this step, measure the distance the test device has moved, ie the distance between the positions when the underside of the test device has reached the value specified above from its original position.

이러한 시험절차에 의해 루프의 앞쪽 모서리에 가할 때 측정한 시험장치가 움직이는 거리를 5인치 이내로 규정하고 있다. 보통 차량 루프의 양쪽을 모두 시험하여야 하지만 일반적으로 한쪽이 성능을 만족하면 다른 한쪽도 만족하는 것으로 간주하고 있다.This test procedure stipulates the distance within 5 inches of the test device measured when applied to the leading edge of the loop. Normally both sides of the vehicle roof should be tested, but in general, when one meets the performance, the other is considered to be satisfied.

상기와 같은 시험은 골격모델과 박판모델을 토대로 하여 이루어지고 이러한 모델들은 차량개발단계의 필수단계라 할 것이다. The above test is based on the skeleton model and the thin plate model, and these models will be referred to as the essential stages of the vehicle development stage.

이와 같이 차량을 개발하는 단계는, 크게 팩케이지 레이아웃(package layout) 단계에서 기본 단면이 결정되고, 프리 마스터(pre master) 단계에서 기본 결합구조가 결정되며, 마스터(master) 단계에서 주요부의 상세 구조 및 보강이 이루어지고, 디테일(detail) 단계에서 상세한 마운팅부의 결정 및 도면이 완성되며 이를 근거로 시작차의 제작에 들어간다.As described above, in the vehicle development stage, a basic cross section is largely determined in a package layout stage, a basic coupling structure is determined in a pre master stage, and a detailed structure of a main part in a master stage. And reinforcement is performed, and the detailed determination of the mounting part and the drawing are completed in the detail stage, and the production of the starting vehicle is started based on this.

상기와 같은 종래의 루프 크러쉬 해석방법은 프리 마스터 단계에서 기본단면의 굽힘 모멘트, 비틀림 상수, 면적이 입력되는 골격모델을 사용한 구조해석이 이루어졌고, 마스터 단계에서는 실제형상이 반영된 박판모델이 실제해석에 적용되어 수행되었다.In the conventional loop crush analysis method as described above, a structural analysis using a skeletal model in which a bending moment, a torsion constant, and an area of a basic section is input in a pre-master step is performed. Applied and performed.

그러나 이러한 종래 루프 크러쉬 테스트 법규는 가혹도가 높은 신법규의 조건 해석시 구법규에 만족하는 모든 중대형 차량들은 테스트를 통과할 수 없다는 문제점이 발생되었다.However, the conventional loop crush test law has a problem that all the medium and large vehicles satisfying the old law cannot pass the test when interpreting the condition of the new law with high severity.

즉, 도 1 및 도 2에 도시된 바와 같이 종래의 신법규 미적용 차량의 단면을 살펴보면, 차체 내측에는 싱글 폐 단면(1) 혹은 2중 폐 단면이 형성되어 있어 신 법규의 조건 해석 시 테스트를 통과할 수 없었다.That is, as shown in Figs. 1 and 2, when looking at the cross section of a conventional non-applicable vehicle, a single closed cross section (1) or a double closed cross section is formed inside the vehicle body and passes the test when analyzing the conditions of the new law. I could not.
