전기-유압 구동 모듈을 적용한 건설기계용 조향 시스템 해석 모델 개발
신민석,조정우,김정길,이상민,이기훈,정영식,오주영 대한기계학회 2020 大韓機械學會論文集A Vol.44 No.12
Conventional hydraulic construction machines are operated by driving a hydraulic pump with the power of an internal combustion engine. However, eco-friendly technologies are being developed to reduce emissions from internal combustion engines and achieve zero emission finally to meet environmental regulations by global warming. In particular, electrically driven drivetrains are being studied that supply electric power by replacing the internal combustion engine with electric motors in the field of construction machinery. In this paper, an electrohydrostatic actuator was applied to the steering system of an electrically drive-train; the system was modeled using a dynamic analysis tool. Then, the developed analytical model was validated against experimental results, which confirmed the applicability to the steering system of the electrohydrostatic actuator module. The developed analytical model will be used as a basic model for sensitivity analysis of design parameters. 종래의 건설기계는 내연 기관의 동력으로 유압 펌프를 구동시켜 생성되는 유압 에너지로 작업을 수행하였다. 그러나 지구 온난화에 의한 환경 규제를 만족시키기 위해서 내연기관에서 배출되는 배기가스를 저감시키거나 내연기관을 전기모터로 대체하여 궁극적으로는 zero-emission을 만족하는 친환경 기술이 개발되고 있다. 본 논문에서는 전기 에너지를 활용하는 전기 구동 건설기계의 조향 시스템에 전기모터로 유압 펌프를 구동하는 전기-유압 구동 모듈을 적용하였으며, 그 성능을 예측하기 위한 해석 모델을 개발하였다. 개발된 해석 모델은 시험 데이터와 비교하여 타당성을 검증하였으며, 전기-유압 구동 모듈의 조향 시스템에 적용 가능성을 확인하였다. 향후, 개발된 모델은 설계 변수의 민감도 해석을 위한 기초 모델로 활용할 예정이다.

In this article, the life of Epiphanius is considered in the reformed point of view, particularly regarding the following four aspects. First, his writing of books on heresies in order to protect Christians in their orthodox faith from sectarian beliefs. Amongst his works, Ancoratus and Panarion were written in the 370s as a defender of the faith in a situation of widespread debates on Arianism and the Christological heresies. Second, his critics of Origen’s teaching on the body and his allegorical exegesis. It is significant to see that Epiphanius’ criticism of Origen was arisen before the outbreak of the Origenist Controversy in the 380s and 390s. Third, his writings against the veneration of images in the church. Greater prominence should be given to Epiphanius in the argument that images of Christ and the saints should be removed from the church, the cemeteries of the martyrs, or private houses. Lastly, his endeavors to reconcile the Antiochene Christian community which was split into four factions. Although Epiphanius was unsuccessful, his efforts to reconcile the church with the Nicene Creed as the centre should be esteemed. Considered from all these facts, it seems fair to title Epiphanius of Salamis as the most influential bishop in the defence of the orthodox faith in the late fourth century AD. 이 논문은 4세기 살라미스의 감독 에피파니우스의 생애와 그의 활동을 개혁신앙의 관점에서 논한 것이다. 크게 네 가지 측면에서 살펴보았는데, 그 첫째는 당시 이단들의 교리로부터 정통신앙을 지키기 위해 저술활동을 펼친 점, 둘째는 오리겐의 알레고리적 성경해석과 성자의 종속절과 육체의 기원/부활에 대한 그의 가르침에 대해 반박한 점, 셋째는 교회의 성상사용과 그리스도인의 성상숭배를 반대한 점, 그리고 마지막으로 니케아 신경을 중심으로 교회의 일치와 화해를 위해 노력했던 점이 그것이다.

This study aims to analysis the migration tendency according to the residents' lifestyle in a large residential estate development. The lifestyle of residents in the suburban area who make their life by agriculture is different from that in the inner city. It may affect on the migration tendencies of the residents. Sin-seo residential land development district is located in the suburban of Daegu is chosen as the case study. This study examines the characteristics of residents' lifestyle and their migration tendency and analyzes the correlation between them. According to the results, the appropriate countermeasures to support the migrants are drawn as follows; First, the people who want to resettle and continue to do farming in the same place should be compensated with housing lands near their farmlands. Second, the residents who want to carry on a small business should be provided with the housing land near to the commercial zones. Third, the size of the new neighborhood unit should be enough to preserve the existing social structure as the social relationship among the neighbors is one of the most important factors in rural communities. Fourth, the high level of housing attachment of the residents needs to remain by maintaining the names of villages and roads of the neighborhoods. It is required to consider the lifestyle of residents and active communities when large residential land development district is planed in the suburban.

This paper addresses the problem of period and priority assignment in networked control systems (NCSs) using a fixed priority scheduler. The problem of assigning periods and priorities to tasks and messages is formulated as an optimization problem to allow for a systematic approach. The temporal characteristics of an NCS should be considered by defining an appropriate performance index (PI) which represents the temporal behavior of the NCS. In this study, the sum of the end-to-end response times required to process all I/Os with precedence relationships is defined as a PI. Constraints are derived from the task and message deadline requirements to guarantee schedulability. Genetic algorithms are used to solve this constrained optimization problem because the optimization formulation is discrete and nonlinear. By considering the effects of communication, an optimum set of periods and priorities can be holistically derived.

OPTIMAL PERIOD SELECTION TO MINIMIZE THE END-TO-END RESPONSE TIME
신민석,이우택,선우명호 한국자동차공학회 2005 International journal of automotive technology Vol.6 No.1
This paper presents a systematic approach which determines the optimal period to minimize performancemeasure subject to the schedulability constraints of a real-time control system by formulating the scheduling problem asan optimal problem. The performance measure is derived from the summation of end-to-end response times of processedhod. The schedulability constraint is specified in terms of allowable resourceutilization. At first, a uniprocessor case is considered and then it is extended to a distributed system connected through acommunication link, local-inter network, LIN. This approach is applied to the design of an automotive body controlsystem in order to validate the feasibility through a real example. By using the approach, a set of optimal periods can easilybe obtained without complex and advanced methods such as branch and bound (B&B) or simulated annealing.

Among the recent fire cases, fires where the combustion point and the ignition point were different occurred. Generally, fire spots are considered as sources of ignition. However, this kind of fire started to ignite in the lower part, but it left little traces and moved to the upper part, causing a large fire damage. The fire inspector must escape stereotypes. This study is based on the assumption that even if there is no trace of carbonization, it can be a point of ignition. Also, a warehouse with a high gap between the upper and lower layers was made into a rehearsal experiment field. In this study, the fake pattern is established as follows. The fire point is different from the combustion point, leaving no carbonized traces. In addition, we study the technique for accurate fire investigation of these fire patterns
