The excavator is a construction machine capable of various tasks such as ditching, trenching, piping, excavating, slope cutting, grading, and rock demoliting. In 2010, unmanned construction machinery using ICT technology has been continuously developed. In general, in hydraulic excavators, This paper investigated the speed limit of the bucket by the load condition and the behavior combination of the boom, arm and bucket through excavator tests. And then, a bucket trajectory was designed in consideration of environmental information (map-based terrain data near the excavator), excavator machine information (excavator kinematic information, excavator hydraulic information), and driver"s wish information (digging start point, dumping start point, and unit loading weight) which are quantified data at the decision stage. The bucket path was verified using the Driving Simulator of excavator.

연구에서는 유압브레이커의 시뮬레이션 결과와 실제 실험 결과의 비교를 통해 시뮬레이션의 타당성을 검증하였다. 유압브레이커의 성능 향상을 위하여 비교적 설계 변경이 용이한 부품의 제원을 설계인자로 선정하였고, 요인시험과 회귀분석을 이용하여 각각의 설계 인자가 유압브레이커의 성능에 미치는 영향을 규명하였다. 본 연구의 결과로 기존 유압브레이커의 성능을 최대화 시킬 수 있는 방안을 제시하였다. In this study, a simulation model developed for a hydraulic breaker is verified through comparison of simulation results to the experimental results. For performance optimization, the design parameters are selected based on the physical parameters of the equipment for ease of modification. Also a factorial experiment and regression analysis were conducted to observe the effect of each parameter on the performance of the hydraulic breaker. As a result, a method for optimizing the performance of a hydraulic breaker is proposed.

In this study I conducted practical experiment to secure the reliability of result obtained through the analysis of hydraulic system in mini loader. Analysis and practical experiment comparison for hydraulic system in mini loader was based upon pressure and flow characteristics in response to boom movement under the same condition. The result shows correspondence of experiment and analysis result. So, I verified the validity of analysis result for the characteristics of mini loader movement in this study.

The excavator consists of boom, arm and bucket, and the boom, arm and bucket are driven by hydraulic cylinder. The clearance of the upper part of the excavator reflects the clearance of the joint part of the hydraulic cylinder and compares the angles of the joint parts and studies the deviation of the bucket behavior due to the clearance of the joint. As the clearance of the joint increases, the angle of rotation of the joint increases, this ultimately affects the deviation of the bucket behavior.

This study is about the architectural publicness of cost guard substation located in Busans fishing port. The development of cities are causing fishing villages to be included in cities, and the phenomenon of being neglected or killed in functional incongruity is being witnessed. In this situation, interest in the ocean is increasing due to the increase in individual leisure time, and it is attracting attention as a center of marine tourism. In line with this, the government is pushing ahead with its fishing port development policy, but discussions on qualitative improvement and understanding of public services and public spaces have not been made due to the plan focused on aesthetic aspects and programs. Therefore, this study attempts to analyze and evaluate the Busan cost guard substation from the perspective of the architectural publicness discussed in fishing ports. Analyzing cost guard substation by dividing them into internal and external public elements, and discuss how to implement architectural publicness from the wide context to the elements of interior space. Based on this, the purpose of the study is to make suggestions on how to implement future-oriented publicness, and this study is meaningful in that it looked at public buildings in Busan from the perspective of architectural publicness.
