Description

차량 엔진의 거동 측정 3축 변위 시스템{Engine behaviour measurement 3 axises deformation system in vehicle}Engine behavior measurement 3 axises deformation system in vehicle

본 발명은 차량 엔진의 거동 측정 3축 변위 시스템에 관한 것으로, 보다 상세하게는 엔진룸에 장착하여 엔진 작동에 따른 거동을 측정할 수 있도록 된 차량 엔진의 거동 측정 3축 변위 시스템에 관한 것이다.The present invention relates to a three-axis displacement system for measuring the behavior of a vehicle engine, and more particularly, to a three-axis displacement system for measuring the behavior of a vehicle engine that can be mounted in an engine room to measure behavior according to engine operation.

일반적으로 차량의 경우 내부에서 고온·고압으로 폭발하여 회전력을 얻는 내연기관을 엔진으로 사용하게 되는데, 이와 같은 엔진은 동력을 발생하는 부분으로서 실린더와 크랭크케이스, 실린더헤드, 피스톤, 크랭크축, 플라이휠, 캠축, 밸브기구등과 같이 많은 장치들로 이루어지게 된다.In general, in the case of a vehicle, an internal combustion engine that obtains rotational force by exploding at high temperature and high pressure is used as an engine. Such an engine generates power, such as a cylinder, a crankcase, a cylinder head, a piston, a crankshaft, a flywheel, It consists of many devices such as camshaft, valve mechanism and so on.

즉, 이와 같이 여러 장치들로 이루어진 엔진은 실린더헤드부위에 구비된 밸브기구를 작동시켜 외부 공기와 인젝터에서 분사되는 연료를 실린더에 형성된 밀폐된 연소실로 공급하여 압축하면서 폭발시켜 작동되는 피스톤의 왕복운동을 크랭크케이스에 구비된 크랭크샤프트를 통해 회전운동으로 변환하여 차량의 동력을 얻게 된다.That is, the engine composed of several devices as described above operates the valve mechanism provided in the cylinder head portion to supply the fuel injected from the outside air and the injector to the closed combustion chamber formed in the cylinder, compresses it, and explodes it to operate the reciprocating motion of the piston. Is converted into rotational movement through the crankshaft provided in the crankcase to obtain the power of the vehicle.

이에 따라, 엔진룸에 장착되는 엔진은 연소실내에서의 폭발이 고속으로 일어나고 이로 인해 엔진 자체에 강한 충격이 지속적으로 가해지면서 엔진에 소음과 함께 진동이 발생되므로 이와 같은, 엔진의 진동을 저감시키기 위해 차량의 엔진룸에 장착 시 가해지는 진동에 대해 댐핑(Damping)작용을 하는 마운팅부시등을 이용하여 차체에 고정시키는 등의 다양한 방법을 이용하게 된다.Accordingly, in order to reduce the vibration of the engine, the engine mounted in the engine room generates an explosion in the combustion chamber at a high speed, which causes the engine to vibrate with noise while a strong impact is continuously applied to the engine itself. Various methods, such as fixing to the vehicle body by using a mounting bush that damps the vibration applied when mounted in the engine room of the vehicle, are used.

그러나, 이와 같이 엔진에서 발생되는 진동을 저감하기 위한 마운팅부시는 그 설치 위치에 따라 진동의 저감 성능이 좌우되므로 차량의 개발시에는 엔진 자체와 엔진에 연결되는 배기계등의 진동을 측정하는 것이 우선적으로 선행되어야 하고, 이에 따라 실제 작동 시 진동 발생부위에 단축 변위계나 또는 엔진부위 전체를카메라로 촬영하는 등의 방법을 통해 엔진 거동에 따른 변위를 측정하게 되지만, 이와 같은 단축변위계는 실제 발생되는 3축방향의 진동을 정확히 측정할 수 없을 뿐만 아니라 카메라에 의한 촬영은 그 데이터를 정량화 할 수 없는 한계가 있게 된다.However, since the mounting bushing for reducing vibration generated in the engine is dependent on the installation position, the vibration of the engine itself and the exhaust system connected to the engine should be measured prior to the development of the vehicle. Therefore, in actual operation, the displacement due to engine behavior is measured by using a single axis displacement meter on the vibration generating part or the entire engine part with a camera, but such a single axis displacement is actually generated in the three axis direction. Not only can not accurately measure the vibration of the camera but also the camera has a limit that can not quantify the data.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 엔진의 작동에 따라 엔진과 함께 연동되는 장치나 부품 및 배기계등에서 발생되는 3축 방향의 진동을 독립적으로 모두 측정하여 정량적 데이터를 확보함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and according to the operation of the engine, it is possible to independently measure all vibrations in the three-axis direction generated from a device, a component interlocked with the engine, and an exhaust system, thereby securing quantitative data. There is a purpose.

상기와 같은 목적을 달성하기 위한 본 발명은, 엔진룸부위에 고정되는 고정플레이트와, 이 고정플레이트에 그 일단이 지지플레이트를 매개로 고정되면서 그 변형이 자유롭도록 이루어진 리프, 이 리프의 타단을 고정하면서 측정부위로 장착되어 3축 방향의 거동을 전달하는 거동부 및 이 거동부로 전달되는 외력에 의해 변형되면서 전기신호를 발생하는 제1·2·3측정부로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, the fixed plate is fixed to the engine compartment, the leaf is fixed to the fixed plate while the one end is fixed via the support plate, the other end of the leaf fixed It is characterized in that it is composed of a first part, a second part, and a third part, which are mounted to the measuring part to transmit the motion in the three-axis direction and the electric part is deformed by the external force transmitted to the moving part to generate an electrical signal.

And first, second, and third measuring units 23, 24, and 25 for generating an electric signal while being deformed by an external force transmitted to the moving part 30.

여기서, 상기 리프(20)는 그 변형이 자유롭도록 형성함과 더불어 소정구간에 변형된 상태를 유지할 수 있는 강성을 부여하도록 보강플레이트(22,22')가 용접으로 고정되어진다.In this case, the leaf 20 is formed to be freely deformed, and the reinforcing plates 22 and 22 'are fixed by welding to provide rigidity capable of maintaining the deformed state in a predetermined section.

또한, 상기 거동부(30)는 리프(20)의 일단을 고정하면서 3축 방향으로 움직이는 볼조인트(31)와, 이 볼조인트(31)가 자유롭게 움직이도록 결합되면서 측정대상부위로 결합되어 그 거동을 전달하는 전달플레이트(32)로 이루어진다.In addition, the behavior part 30 is fixed to one end of the leaf 20, the ball joint 31 moving in the three-axis direction, the ball joint 31 is coupled to the measurement target site while being coupled to move freely, the behavior It consists of a delivery plate 32 for transmitting.

한편, 상기 제1·2·3측정부(23,24,25)는 3축(T,L,H)방향의 변위를 측정할 수 있는 임의의 부위에 장착되지만, 3축(T,L,H)방향의 변위를 가장 잘 전달하는 거동부(30)부위로 장착되는 것이 바람직함은 물론이다.On the other hand, the first, second, third measurement unit (23, 24, 25) is mounted on any part that can measure the displacement in the three-axis (T, L, H) direction, the three-axis (T, L, Of course, it is preferable to be mounted to the moving part 30 that transmits the displacement in the H) direction best.

그리고, 상기 제1측정부(23)는 도 2에 도시된 바와 같이 평행사변형의 각 변에 T축 성분의 거동인 전·후 방향의 움직임을 측정하도록 각각 스트레인게이지(Rgt1,Rgt2,Rgt3,Rgt4)를 구비하여 수평성분으로 여기(Excitation)되고 수직성분으로 출력(E ; Output)이 나오도록 구성된다.As shown in FIG. 2, the first measuring unit 23 measures strain gauges Rgt1, Rgt2, Rgt3, and Rgt4 to measure the forward and backward movements of the T-axis component on each side of the parallelogram. ) Is configured to be excited with a horizontal component and an output (E) with a vertical component.

또한, 상기 제2측정부(24)는 도 3에 도시된 바와 같이 평행사변형의 인접된 두 변에 L축 성분의 거동인 좌·우 방향의 움직임을 측정하도록 각각 스트레인게이지(RgL1,RgL2)를 구비함과 더불어 이에 대향되는 두 변에는 더미(Dummy)저항을 구비하여 수평성분으로 여기(Excitation)되고 수직성분으로 출력(E' ; Output)이 나오도록 구성된다.In addition, as shown in FIG. 3, the second measuring unit 24 measures strain gages RgL1 and RgL2 on two adjacent sides of the parallelogram to measure the movement in the left and right directions of the L-axis component. In addition, the two sides opposite to each other are provided with a dummy resistor to excite the horizontal component and output the vertical component E '.

한편, 상기 제3측정부(25)는 도 3에 도시된 바와 같이 제2측정부(24)의 스트레인게이지(RgL1,RgL2)가 설치된 평행사변형의 인접된 두 변에 H축 성분의 거동인 상·하 방향의 움직임을 측정하도록 각각 스트레인게이지(Rgh1,Rgh2)를 구비하게 된다.Meanwhile, as shown in FIG. 3, the third measuring unit 25 has a behavior of an H-axis component at two adjacent sides of a parallelogram having strain gages RgL1 and RgL2 of the second measuring unit 24 installed. Strain gauges Rgh1 and Rgh2 are provided respectively to measure movement in the downward direction.

이에 따라, 본 발명에 따른 3축 변위 시스템을 이용하여 엔진과 배기계의 작동에 따른 거동을 측정하고자 하면 먼저, 시스템을 이루는 고정플레이트(10)를 적정한 엔진룸부위에 고정하고 이의 반대부위를 이루는 거동부(30)를 측정대상부위로 설치하게 된다.Accordingly, to measure the behavior according to the operation of the engine and the exhaust system using the three-axis displacement system according to the present invention, first, the fixing plate 10 constituting the system is fixed to an appropriate engine room part and the opposite part thereof is formed. The eastern part 30 will be installed as the measurement target site.

이때, 상기 3축 변위 시스템의 측정부(23,24,25)를 통해 발생되는 출력신호를 전송 받아 기록하고 분석하는 장치들이 엔진룸이외의 장소에 설치됨은 물론, 이러한 장치들은 일반적으로 구성되므로 상세한 설명을 생략한다.At this time, the devices for receiving, recording and analyzing output signals generated through the measuring units 23, 24, and 25 of the three-axis displacement system are installed in places other than the engine room, and these devices are generally configured, so detailed Omit the description.

이후, 엔진의 작동에 따라 발생되는 측정 대상의 3축(T,L,H)방향의 변위가 거동부(30)를 통해 리프(20)로 전달되고 이에 따라, 제1·2·3측정부(23,24,25)가 각 축 방향에 따라 변화되면서 이에 상응되는 전기신호를 보내 좌·우 방향(L축)의 변위에 대한 제3측정부(25)의 상태를 분석한 도 4에 도시된 바와 같이 거동 변위에 대한 파형 선도를 기록하게 된다.Subsequently, the displacement in the three axis (T, L, H) direction of the measurement target generated according to the operation of the engine is transmitted to the leaf 20 through the behavior part 30, and accordingly, the first, second and third measurement parts. As shown in FIG. 4 in which (23, 24, 25) is changed in each axis direction and an electric signal corresponding thereto is transmitted to analyze the state of the third measuring unit 25 for displacement in the left and right directions (L axis). As shown, the waveform plot for the behavioral displacement is recorded.

즉, 이를 다시 설명하면 먼저, 전·후 방향(T축)의 거동을 측정하는 제1측정부(23)는 거동부(30)의 볼조인트(31)에서 전·후 방향(T축)의 움직임을 받아 평행사변형의 각 변에 구비된 스트레인게이지(Rgt1,Rgt2,Rgt3,Rgt4)에 비틀림이 발생되면서 예를 들어, 전방방향의 거동 시 저항 값을 감소시키고 후방방향의 거동 시 저항 값을 증가시키도록 상응하는 저항 값에 해당되는 전기신호인 아웃푸트(E, Output)를 출력하여 도 5에 도시된 바와 같은 파형으로 변환하여 표시하게 된다.That is, to explain again, first, the first measuring unit 23 measuring the behavior of the front and rear directions (T axis) is the ball joint 31 of the behavior part 30 of the front and rear directions (T axis). As the torsion occurs in the strain gauges Rgt1, Rgt2, Rgt3, and Rgt4 provided on each side of the parallelogram under the movement, for example, the resistance value decreases during forward movement and the resistance value increases during backward movement. In order to output an output signal (E, Output) corresponding to a corresponding resistance value, it is converted into a waveform as shown in FIG. 5 and displayed.

또한, 본 발명은 좌·우 방향(L축)과 상·하 방향(H축)의 거동을 측정하는 제2·3측정부(24,25)도 전술한 바와 같이 거동부(30)의 볼조인트(31)에서 좌·우 방향(L축)과 상·하 방향(H축)의 움직임을 받아 평행사변형의 각 변에 구비된 스트레인게이지(RgL1,RgL2,Rgh1,Rgh2)에 비틀림이 발생되면서 즉, 좌측과 상방향의 거동 시 저항 값을 감소시키고 우측과 하방향의 거동 시 저항 값을 증가시키도록 상응하는 저항 값에 해당되는 전기신호인 아웃푸트(E, Output)를 출력하여 도 4에 도시된 바와 같은 파형으로 변환하여 표시하게 된다.In addition, according to the present invention, the second and third measuring units 24 and 25 for measuring the behaviors in the left and right directions (L axis) and the up and down directions (H axis) are also described. Torsion occurs in the strain gauges RgL1, RgL2, Rgh1, and Rgh2 provided on each side of the parallelogram under the movement of the left and right direction (L axis) and the up and down direction (H axis) in the joint 31. That is, the output signal (E, Output) corresponding to the corresponding resistance value is outputted in FIG. 4 so as to reduce the resistance value in the left and the upside direction and increase the resistance value in the right and the downside direction. The waveform is converted to and displayed as shown.

이상 설명한 바와 같이 본 발명에 의하면, 엔진의 작동에 따라 발생되는 진동을 3축 방향으로 분리하여 그 각각의 거동에 따른 변위를 저항 값으로 변화시켜 측정하고자 하는 두 지점에 대한 3축 ??위를 정량적으로 계측하게 되므로 특히, 차량의 급출발이나 급 제동에 의한 엔진 거동에 따른 와이어와 마운팅부시등의 설계 시 작용하는 외력에 대한 변형과 거동등을 정확하게 판단하여 설계기준과 평가기준을 설정하는 데이터로서 활용 할 수 있는 효과가 있게 된다.As described above, according to the present invention, the vibration generated according to the operation of the engine is separated in three axes, and the displacement according to the respective behavior is changed to the resistance value so that the three axes of the two points to be measured are measured. As it is measured quantitatively, it is a data that sets the design standard and evaluation standard by accurately determining the deformation and behavior of external force acting in the design of wire and mounting bush, etc., due to the engine behavior caused by rapid starting or braking of the vehicle. There is an effect that can be utilized.
