A Study on The Noise Teduction Effects of Heliports by the Height of Noise Barrier
박 정 태 · 김 홍 현 · 정 상 조 · 최 형 진
Jungtae Park, Hong-Hyun Kim, Sangjo Jeong and Hyung-Jin Choi
To analyze the characteristics of noise occuring during helicopter operation, in this study, representative military heliports with noise barriers were selected and the noise was measured with respect to the direction (front, rear, and side) and distance. Furthermore, to measure the effect of noise on nearby households and calculate the effectiveness of the noise barrier, the noise at...

Study on the Yo-yo Vibrational Energy Harvester applied to the Wave Power Generation
장 선 준 · 김 병 룡
Seon-Jun Jang and Byeong-Ryong Kim
This study focuses on a yo-yo vibrational energy harvester tuned to a low frequency, which is common among ocean waves. The proposed device can be installed inside a buoy and is, thus, protected from the harmful marine environment. It is demonstrated that the excessive static deflection observed in the springs of conventional translational vibrating systems can be minimized...

Development of Intelligent Vibration Compensator for the Vibration Suppression of Structures Excited by Harmonic Disturbance
김 수 민 · 곽 문 규 · 김 극 수
Soo-Min Kim, Moon-Kyu Kwak and Kuk-Su Kim
The structure of a ship is inevitably subjected to vibrations caused by many excitation sources, such as the engine, the propeller, and sea waves. Moreover, the natural vibration characteristics of a ship tend to vary owing to the loading and operating conditions. Over recent years, given the decreasing weights of hulls and the increasing speeds of engines, the possibility of resonance...

Hyungsuk Han, Soohong Jeon, Chungwon Lee, Dong-Nyok Lee, Yonghoon Kim and Sock-Kyu Lee
Underwater radiated noise is considerably important for naval vessels to detect enemy ships and also to prevent detection by them. Therefore, underwater noise must be maintained below the preliminary specified level during the design stage. However, underwater radiated noise can vary depending on the various sea and ship conditions. As the sound of propeller...

Motion Phase-based 2-Dimensional Displacement Measurements under Various Illumination Conditions with Maker and Filter Design
공 예 슬 · Miao Yinan · 전 준 영 · 박 규 해
Yeseul Kong, Yinan Miao, Jun Young Jeon and Gyuhae Park
The advanced displacement measurement technique using computer vision has shown several advantages, such as a high spatial resolution and no mass loading effect, compared to the conventional contact-sensing techniques. However, the accuracy and robustness of vision-based techniques are subjected to various illumination conditions, including uneven illumination...

Mechanical Property Analysis of Silk Fiber Based on Principal Component Analysis
김 윤 중 · 윤 태 영 · 박 우 범 · 장 현 준 · 나 성 수
Yoonjung Kim, Taeyoung Yoon, Wooboum Park, Hyunjoon Chang and Sungsoo Na
Silk has excellent mechanical properties such as seven times the toughness of Kevlar 49 fiber; hence, it is considered as a candidate for the next generation fiber material. Although it is known that the crystalline region contributes largely to its mechanical properties, spider silk and silkworm silk use different amino acid sequences for the crystalline region. To determine the reason for the...

Shape Dependence of Air-balloon for Propeller-cavity Induced Hull Excitation Mitigation
이 정 훈 · 신 윤 호
Jeung-Hoon Lee and Yun-Ho Shin
The air-balloon is a simple, yet effective, device that can suppress propeller cavitation induced hull excitations using the principle of acoustic destructive interference. It is vital to have an accurate balloon destructive fre-quency for a design. The present study assumed the balloon as an oblate spheroid rather than as an ideal sphere. Beginning with the exact modal-series solution, we...
선체 진동신호의 DEMON 분석 단순화 및 Cross Entropy를 이용한
함정 CIS 판정 지표 연구
Study on Simplification Method of DEMON analysis and Quantified Evaluation Indicator for CIS Judgement Using Cross Entropy
김 용 훈 · 한 형 석 · 전 수 홍 · 이 청 원 · 이 동 녁 · 이 석 규
Yonghoon Kim, Hyungsuk Han, Soohong Jeon, Cheongwon Lee, Dong-Nyok Lee and Sock-Kyu Lee
The Detection of Envelope Modulation on Noise (DEMON) method is widely used to detect the propeller cavitation noise signals of naval surface ships. In the DEMON method, the accuracy of analysis strongly tends to rely on the user skill and experiences because noise signals must be investigated visually and qualitatively. This study suggests a quantitative indicator that detects the...
Voice Coil Actuator를 이용한 고속조준기의 구조설계 및 신뢰성

A Study for Reliability Verification of Structural Design of Fast Steering Mirror with Voice Coil Actuators
유 준 선 · 임 선 빈 · 정 재 우 · 정 상 원 · 김 재 현 · 윤 준 영 · 이 승 한 · 곽 도 현 · 정 의 봉 · 박 노 철
Junsun Yoo, Seonbin Lim, Jae Woo Jung, Sang Won Jung, Jae Hyun Kim, Jun Young Yoon,
Seoung-Han Lee, Do Hyun Kwak, Eui-Bong Jeong and No-Cheol Park
Because laser weapons are relatively easy to use and can exert powerful energy with high efficiency versus cost, the laser weapons are being developed competitively in the defense industry. A fast steering mirror is the key component for precision tracking and automatic beam alignment, which are the main performances of laser weapons. The purpose of this study is to verify the...

A Study on a Machine Learning Model to Classify Road Pavement Types Based on Acoustic and Image Data for Road Maintenance
김 보 경 · 이 재 관 · 최 호 식 · 장 서 일 · 이 수 일
Bo Kyeong Kim, Jae Kwon Lee, Ho Sik Choi, Seo Il Chang and Soo Il Lee
The investigation of tire-road noise according to the type of road pavement is time-consuming and expensive. In this study, an artificial neural network model was applied to address this problem. Models to classify road pavement types (for example, transverse-tined, longitudinal-tined, NGCS, DG, and SMA) were implemented and their performance were compared. Input data were...

Economic Incentive System for Noise and Vibration Reduction
강 광 규 · 김 경 민 · 박 영 민
Kwang Kyu Kang, Kyoung Min Kim and Young Min Park
To reduce noise and vibration at construction sites, the emission allowance standard system under the current law has been enforced, but there is a limit to managing and supervising several construction sites unless they are constantly monitored by a monitoring device. The existing system has a limit in mitigating noise disputes at construction sites. It is a well-known fact that proactive...
