Claims (4)

진동을 유발시키는 가진기(E)를 선체의 일 지점에서 설치하고, 진동을 측정하고자하는 모든 부위에 설치된 진동센서(S)를 멀리 찬넬 증폭기에 연결하되, 그 증폭값을 마이크로 컴퓨터에 신호하도록 연결하며, 이 컴퓨터는 선체 진동응답특성을 분석할 수 있는 소프트웨어에 의하여 선체의 진동 특성을 모니터로 표시해 주게끔 연결 구성하여서 된 것을 특징으로 하는 선박의 진동 측정 시험 장치.Install the vibrator (E) that causes vibration at one point of the hull, and connect the vibration sensor (S) installed at all parts to measure the vibration to the channel amplifier, and signal the amplification value to the microcomputer. And the computer is configured to connect the monitor to display the vibration characteristics of the hull by a software that can analyze the vibration response characteristics of the hull. 진동 취약 요소에 가진기(E)를 설치하고 진동경로에는 진동센서(S)를 부착하여 이 진동신호를 증폭기에 전달하도록 연결하며 증폭기는 콘트롤러의 입력단의 연결하는 한편, 그 출력단에는 가지기의 서보밸브(7)와 연결되게하고 또한 가진기 바닥의 로드셀(1)로부터 콘트롤러로 다시 연결하여 진동량을 피드백되게 함으로서 콘트롤러에서는 고유 진동신호와 가진기의 진동량을 비교하면서 대응진동을 가질 수 있도록 연결 수성함을 특징으로 하는 선박의 진동 제어장치.Install the vibrator (E) on the vibration weakening element, and attach the vibration sensor (S) to the vibration path to transmit this vibration signal to the amplifier.The amplifier connects to the input terminal of the controller and has a servo valve at the output terminal. (7) and by connecting back to the controller from the load cell (1) at the bottom of the vibrator so that the vibration amount is fed back, the controller compares the natural vibration signal with the vibration amount of the vibrator and can have a corresponding vibration. Vibration control device of the ship characterized by the name. 선체면(H)에 로드셀(1)을 안착하고 그 위에 중공형 프레임(2)를 얹히며 상단부에는 서보밸브(7)를 통하여 압송되는 유압이 실린더(3)를 작용시키도록 설치하되, 내부의 피스톤로드(4)에는 하단에 가속도계(5)를 부착하며, 상부에는 중량체의 매스(6)를 달아 모터(M) 및 펌프(P)에 의한 유압이 서보밸브(7)로 압송될 때 별도의 콘트롤로 명령에 따라 서보밸브(7)가 개폐 운동하여 유압의 힘으로 매스(6)를 포함한 피스톤이 상하로 진동을 유발할 수 있도록 구성함을 특징으로 하는 가진기.The load cell (1) is seated on the hull surface (H) and a hollow frame (2) is placed thereon, and the upper end is installed so that the hydraulic pressure pushed through the servo valve (7) to operate the cylinder (3), An accelerometer 5 is attached to the piston rod 4 at the lower end, and the mass 6 of the weight is attached to the upper part so that the hydraulic pressure by the motor M and the pump P is separately transferred to the servovalve 7. The servo valve (7) according to the command of the control of the exciter, characterized in that configured to cause the piston including the mass (6) to induce vibration up and down by the hydraulic force. 제3항에 있어서, 가진기(E)의 프레임(2) 상단부가 역으로 설치되어 매스(6)가 중공부내에 위치되고 가속도계(5)는 상안에 위치하는 상태로 실린더를 구성하는 가진기.4. The vibrator according to claim 3, wherein the upper end of the frame (2) of the exciter (E) is installed in reverse so that the mass (6) is located in the hollow and the accelerometer (5) is located in the top. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
