Abstract

본 발명은 선박이나 대형 구조물의 변형량을 측정하여 이의 변형량을 알아내고 이것으로부터 구조물에 걸리는 응력을 계산하여 구조물에 과도한 응력이 걸리는가를 감시하기 위한 시스템에 관한 것이다.The present invention relates to a system for monitoring whether a stress is applied to a structure by measuring a deformation amount of a ship or a large structure, finding a deformation amount thereof, and calculating a stress on the structure therefrom.

종래의 장치의 동작원리는 구조 스트레인게이지형으로서 이는 구조물의 변형량을 스트레인게이지로 직접 계측하는 방법을 취하였던바 이 방법의 문제점에 있어서는, 첫째로는 온도의 변화에 대한 구조물의 변형률(량)을 고려하기가 매우 어렵고 (열팽창 계수가 구조물과 같은 막대를 사용하므로서 보상하는 경우도 있으나 실제로 구조물자체의 온도와 공기가 잘 통하고 그늘에 설치하는 계측장치의 온도는 차이가 많이 나므로 온도보상이 제대로 이루어지지 않았다) 둘째로는 스트레인게이지 자체가 온도변화에 대한 사용범위가 넓지 못하였던 것이다.The operation principle of the conventional apparatus is a structure strain gauge type, which is a method of directly measuring the deformation amount of a structure with a strain gauge. In the problem of this method, first, the strain (amount) of a structure against a change in temperature is determined. It is very difficult to consider (compensation is made by using the same rod as the structure, but in actuality, the temperature of the structure itself is different from the temperature of the measuring device installed in the shade. Second, the strain gauge itself was not widely used for temperature changes.

본 발명은 이상의 문제점을 해결하고자 발명한 것으로의 이의 발명요지는 선체나 구조물의 변형량을 막대의 회전운동으로 바꾸어 그 양을 증폭하고 또한 직각방향으로 보조막대를 대어서 온도에 따른 변형량을 보상함으로서 선체나 대형구조물이 순수한 외력에 의한 변형량만을 측정할 수 있게한 것이다.The present invention has been made to solve the above problems, the present invention is to change the amount of deformation of the hull or structure to the rotational movement of the rod to amplify the amount and to compensate for the amount of deformation according to the temperature by applying the auxiliary rod in the perpendicular direction to the hull or Large structures can only measure the amount of deformation caused by pure external force.

Claims (1)

스트레인게이지를 사용하지 아니하고 구조물의 신축을 막대의 회전운동으로 바뀌어 측정함에 있어 막대 ι2와 ιL₃의 길이의 비를 조정함으로써 구조물의 변형량을 증폭시켜 계축의 정도를 높히며, 구조물이 온도의 변화에 의해 생기는 변형량 보상은 측정하고자 하는 방향과 직각으로 보조막대를 설치함으로써 온도의 변환에 의한 구조물의 변형량을 보상할 수 있게하고, 막대의 위 방향에 스프링(K₁K₂)을 설치함으로써 외력에 의한 막대의 진동을 줄일 수 있게하며 갭센서를 사용함으로써 극심한 온도환경에 노출시에도 정도측정이 가능케한 대형 구조물의 변형량 측정장치.In measuring the expansion and contraction of the structure by the rotational movement of the rod without using the strain gauge, by adjusting the ratio of the lengths of the bar ι 2 and ιL₃, the deformation of the structure is amplified to increase the degree of the axis, and the structure is subjected to changes in temperature. The compensation of deformation caused by the auxiliary bar is installed at right angles to the direction to be measured to compensate for the deformation of the structure due to the change of temperature, and the vibration of the rod caused by external force by installing a spring (K₁K₂) in the upper direction of the bar. Deformation measuring device of large structure that can measure the accuracy even when exposed to extreme temperature environment by using gap sensor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
