이 논문은 승용차용에 사용되는 휴즈박스 자동조립기의 개발에 관한 연구로서 기존 시스템은 휴즈를 낱개로 수동 공급하여 스위치의 조작에 의해 압입하여 조림하였으나 이 연구에서는 자동공급피더에 의해 휴즈를 자동으로 공급시키고 센서의 감지에 의한 자동 압입을 실시하는 장치로써 생산성을 대폭 향상시킨 것이라 할 수 있다.

본 논문은 자동차용 퓨즈 및 릴레이 박스의 취부상태를 검사하기 위한 비전시스템의 구현 예를 보여준다. 검사를 위한 vision system은 영상 취득부와 검사 알고리즘, 그리고 사용자 인터페이스의 세 부분으로 구성된다. 영상 취득부는 box의 영상을 grabbing하는 부분으로 조명부와 광학부로 이루어진다. 검사 알고리즘은 영상을 이용하여 검사작업을 수행하는 부분이다. 사용자 인터페이스는 fuse & relay box의 모양과 부착되는 fuse와 relay를 등록하기 위한 사용자 인터페이스와 검사 작업을 수행하기 위한 사용자 인터페이스 두 부분으로 이루어진다. 본 연구에서 제시하는 검사 알고리즘은 신뢰도가 높아 실제 생산 현장에 사용이 가능하다.

자동차는 발명 초기 형태로 부터 많은 발전과 변형을 거듭하여 현재의 형태에 이르기 까지 인간의 활동 영역을 넓혀 주고 있다. 자동차의 전자 부품중 하나인 정션 박스를 종래에는 사람이 직접 육안으로 검사하여 오판을 하거나 검사의 속도가 느린 문제점이 있었다. 이를 보완하여 빠르고 정확하게 정션 박스 검사를 하기 위하여 비전 시스템(Vision System)을 이용하여 공정을 자동화 하는 방법을 제시하였다. 본 논문은 정션 박스에 삽입된 퓨즈(Fuse)와 릴레이(Relay)의 색상과 표면의 패턴을 검사하여 이상 유/무 및 결함을 자동으로 검사한다. 불량 검출의 성능을 평가하기 위하여 정션 박스를 가지고 시스템의 성능을 평가한 결과, 100%의 인식률을 나타내었고 이를 산업체에 적용하여 신속하고 정확한 검사가 가능함을 보였다.

In this paper, a particular type of all-steel HSS brace members with a locally reduced cross-sectional area was experimentally and numerically investigated. The brace member was strengthened against local buckling with inner and outer boxes in the reduced area. Four single-span braced frames were tested under cyclic lateral loadings. Specimens included a simple steel frame with a conventional box-shaped brace and three other all-steel reduced section buckling-restrained braces. After conducting the experimental program, numerical models of the proposed brace were developed and verified with experimental results. Then the length of the proposed fuse was increased and its effect on the cyclic behavior of the brace was investigated numerically. Eventually, the brace was detailed with a fuse-to-brace length of 30%, as well as the cross-sectional area of the fuse-to-brace of 30%, and the cyclic behavior of the system was studied numerically. The study showed that the proposed brace is stable up to a 2% drift ratio, and the plastic cumulative deformation requirement of AISC (2016) is easily achieved. The proposed brace has sufficient ductility and stability and is lighter, as well as easier to be fabricated, compared to the conventional mortar-filled BRB and all-steel BRB.

According to the National Fire Data System (NFDS), more than 5,000 vehicle fires have occurred every year for the last 10 years. Vehicle fires are primarily caused by mechanical (breaking system and engine), electrical (wiring and battery), and chemical (oil and fuel gas leakage) problems. The electrical factor has increased with the installation of driver convenience equipment. For example, today, the black box is widely used to provide video data recording of motor vehicle accidents. The black box consists of a front camera, rear camera, and wires. The black box wires are directly connected to the junction box or fuse box from the start battery that operates to provide normal on power supplying for engine stop. It is extremely dangerous when the wires short circuit due to insulation aging, mechanical and electrical stress, etc. In this study, the black box wiring fire risk have been analyzed and investigated when the steady state and abnormal operations, and under the following conditions: wiring arrangements with a high temperature condition, insulation aging, poor contact, and short circuits. The results showed that black box wiring short circuits had a higher fire risk than the other fire hazard elements. To prevent fire hazards caused by black box wiring, the black boxes must be installed by qualified service personnel. Do not modify the wiring, remove the fuse and secure the wiring using cable ties or insulation tape.

Recently a large number of electronic control devices are abruptly increasing in vehicles as the electronic industry advances. Also the number of wiring harnesses and complexity of wiring is proportionally increased to the devices. A newly developed connector named bridge connector is introduced in this study for the purpose of the wiring structure changes. A wiring structure among distributed control systems by using serial communication is proposed with the bridge connector in this paper. The bridge connector contains a auto-recovery fuse made by PTC thermistor material for the protection of the over-currents on local control devices. The auto-recovery function of the fuse is needed for the maintenance free system in the distributed controls. The PTC fuse characteristics organized in this study is tested and the results are showed in detail for the real application.

This study set three kinds of situation and observed the various states such as carbonization by experimenting damages by fire of electric iron. The results of this study are as follows: The fire did not occurred when the unpowered iron over mattress and cotton shirts was com busted completely by external flame because the temperature of surface of soleplate and mattress did not reach the minimum ignition energy and when the powered electric iron over mattress and cotton shirts was left for an hour with its temperature dial set to high because the temperature of combustibles did not reach the minimum ignition energy. The fire occurred when the electric iron in which the outer box, bi-metal switch, and temperature fuse were removed over mattress and cotton shirts was powered by through heater terminal, and then the electric iron, mattress, and cotton shirts were combusted by the fallen combustibles because the temperature of combustibles reached to the minimum ignition energy with the help of active transfer of heat.
