Description

자동차의 진동시험용 가속도계 결합구{COUPLED ELEMENT OF AN ACCELEROMETER FOR OSCILLATION TEST OF A VEHICLE}Accelerometer Coupling for Vibration Testing of Vehicles {COUPLED ELEMENT OF AN ACCELEROMETER FOR OSCILLATION TEST OF A VEHICLE}

본 발명은 자동차의 진동시험용 가속도계 결합구에 관한 것으로, 특히 자동차의 진동시험시 가속도계의 설치 및 제거를 간편하면서도 용이하게 할 수 있도록 한 자동차의 진동시험용 가속도계 결합구에 관한 것이다.The present invention relates to an accelerometer coupler for vibration testing of a vehicle, and more particularly, to an accelerometer coupler for vibration testing of a vehicle that enables easy and easy installation and removal of an accelerometer during a vibration test of a vehicle.

일반적으로, 차량의 진동과 소음을 저감하기 위한 연구나 평가 시에는 차체모형을 지지하는 고정지그의 각 부위에 여러 개의 가속도계를 부착하여 차량의 모드 해석 실험을 하게 된다.In general, when conducting research or evaluation to reduce the vibration and noise of the vehicle, a plurality of accelerometers are attached to each part of the fixing jig supporting the body model, and the mode analysis experiment of the vehicle is performed.

이와 같은 종래 기술의 진동시험용 가속도계를 부착할 시에는 가속도계를 차체모형의 고정지그에 직접 부착하는 방법이 사용되고 있다.When attaching the accelerometer for vibration testing of the prior art as described above, a method of directly attaching the accelerometer to a fixed jig of a vehicle body model is used.

도 1은 종래 자동차의 진동시험시 가속도계의 설치상태를 나타낸 결합단면도로서, 종래 차량의 진동시험 시에는 시험대상물(미도시)에 진동을 가하는 엑츄에이터(미도시)를 포함한 진동시험기(1)가 구비되어 있다. 진동시험기(1)의 상측에는 상기 엑츄에이터의 동작에 의해 구동되고, 복수개의 결합홈(2)이 형성된 평면의 가진판(3)을 포함하고 있다. 가진판(3)의 상부면에는 상기 시험대상물을 고정 지지하는 고정지그(4)를 설치한다.1 is a cross-sectional view showing an installation state of an accelerometer in a vibration test of a conventional vehicle, and a vibration tester 1 including an actuator (not shown) for applying vibration to a test object (not shown) during a vibration test of a conventional vehicle is provided. It is. An upper side of the vibration tester 1 is driven by the operation of the actuator, and includes a flat excitation plate 3 on which a plurality of coupling grooves 2 are formed. A fixing jig 4 for fixing and supporting the test object is installed on the upper surface of the excitation plate 3.

또한, 고정지그(4)의 일측면에는 결합홈(2)에 대응되는 위치에 복수개의 관통홀(5)이 형성되어 있다.In addition, a plurality of through holes 5 is formed at one side of the fixing jig 4 at a position corresponding to the coupling groove 2.

한편, 가진판(3)의 상부면에 고정지그(4)를 설치할 경우, 관통홀(5) 및 결합홈(2)에 체결되는 전용볼트(6)등의 결합수단을 사용하여 결합한다.On the other hand, when the fixing jig (4) is installed on the upper surface of the excitation plate (3), it is coupled using a coupling means such as a dedicated bolt (6) fastened to the through hole (5) and the coupling groove (2).

그리고, 고정지그(4)의 상부면에는 진동의 측정을 위해 복수개의 가속도계(7)를 고정 설치하는 바, 가속도계(7)의 저면에는 일반적으로 피대상물(미도시)에 볼트등의 결합수단을 사용하여 고정 결합하기 위한 암나사부(미도시)가 형성되어 있다.In addition, a plurality of accelerometers 7 are fixedly installed on the upper surface of the fixing jig 4 to measure vibration, and generally, coupling means such as bolts are attached to an object (not shown) on the bottom of the accelerometer 7. A female thread part (not shown) is formed to be fixedly coupled to use.

한편, 종래에는 고정지그(4)에 가속도계(7)를 설치할 경우, 가속도계(7)의 저면에 형성된 암나사부를 이용하기 위해서는 고정지그(4)의 상면에 가속도계(7)의 설치 위치에 대응되도록 미도시된 복수개의 결합홀을 마련하고, 상기 결합홀을 통해 가속도계(7)의 암나사부에 맞는 전용볼트(미도시)를 사용하여 결합해야 하기 때문에, 설치작업의 공정이 복잡해지는 문제점이 있었다.On the other hand, conventionally, when the accelerometer 7 is installed on the fixing jig 4, in order to use the female thread formed on the bottom of the accelerometer 7, the upper surface of the fixing jig 4 does not correspond to the installation position of the accelerometer 7. Since a plurality of coupling holes shown in the drawing and coupling are required using a dedicated bolt (not shown) suitable for the female screw portion of the accelerometer 7 through the coupling hole, there is a problem in that the installation work is complicated.

따라서, 이러한 문제점으로 인해 통상적으로 가속도계(7)의 저면에는 순간접착제(8)를 발라서 고정지그(4)의 상부면에 간단히 결합하여 설치하였다.Therefore, due to such a problem, the bottom surface of the accelerometer 7 is typically applied by applying a quick glue 8 to the upper surface of the fixing jig 4 simply installed.

상기 결합이 완료된 후, 진동시험기(1)의 가진판(3)이 상기 액츄에이터를 통해 진동되면, 진동시험기(1)의 상부에 결합된 고정지그(4) 및 상기 시험대상물에 진동이 가해지고 진동조건하에서 진동시험이 이루어진다.After the coupling is completed, when the vibration plate 3 of the vibration tester 1 is vibrated through the actuator, the vibration is applied to the fixed jig 4 and the test object coupled to the upper part of the vibration tester 1 and the vibration Vibration tests are performed under conditions.

그러나, 이와 같이 종래 차량의 진동시험을 마친 후, 가속도계(7)를 제거해야 하는데, 가속도계(7)의 제거 시 순간접착제(8)의 접착성분이 가속도계(7)의 저면에 잔존함으로써, 가속도계(7)에 잔존한 접착성분을 제거해야하는 별도의 작업을 수행하는 불편한 문제점이 있다.However, after completing the vibration test of the conventional vehicle as described above, the accelerometer 7 should be removed. When the accelerometer 7 is removed, the adhesive component of the instant adhesive 8 remains on the bottom of the accelerometer 7. There is an uncomfortable problem of performing a separate operation to remove the remaining adhesive components in 7).

본 발명은 전술한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 자동차의 진동시험시 가속도계의 설치 및 제거를 간편하면서도 용이하게 할 수 있도록 자동차의 진동시험용 가속도계 결합구를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide an accelerometer coupler for vibration testing of the vehicle to facilitate and easily install and remove the accelerometer during the vibration test of the vehicle.
