Abstract

On the basis of structural analysis of the radial gate(that is, Tainter gate), this paper focuses on the optimization of the moment distribution according to the location of the arm of the radial gate. In spite of its importance from economical view point, we could hardly find the study on the optimum design of radial gate. Accordingly, the present study identifies the optimum section modulus for a radial arm along with the optimum position for 2 of 3 radial arms with a convex cylindrical skin plate relative to a given radius of the skin plate curvature, pivot point, water depth, ice pressure, etc. These optimum measurements are then compared with previously constructed radial gates. The results indicate that the optimum section modulus vague for a radial arm was appreciably smaller than the previously constructed examples.

이 논문은 회전식 수문(radial gate)의 구조해석에 근거하여 지지점 위치에 따른 모멘트 분배를 최적화하는 것에 관심을 두고 있다. 회전식 수문(radial gate)의 경제적인 관점에서의 중요성에도 불구하고 이의 지지점 위치에 따른 최적설계에 관한 자료를 찾기 어려운 실정이다. 그래서 본 연구에서는 주판(skin plate)의 곡률 반경, 수심, 동압 등의 주어진 자료를 이요약하여 지지점(gate arm)의 수가 2개인 경우와 3개인 경우에 대하여 곡선형태의 주판(skin plate)에서 지지점 (arm)의 최적 위치를 얻어서 설계자료에 의한 것들과 비교한다. 그 결과 최적 설계에 의한 회전식 수문 (radial gate)의 치수가 설계자료에 의한 것에 비해 현저히 감소되는 것을 알 수 있다.
