기존의 밸브 수압측정기는 압력조절을 수동으로 조절함으로서 정확한 압력측정을 할 수 없는 불편함이 있었다. 이를 밸브의 수압측정 시 압력조절센서를 이용하여 압력조절을 안전하고 정확하게 개선한다. 또한 3차원 유한요소 코드인 ANSYS를 활용하여 설계된 수압측정기에 대하여 구조해석을 수행하여 수압측정기 내부압력에 따른 내부누수, 응력, 변형률, 총변형량 등을 구하였다.

Existing hydraulic valve meter used in industrial fields precise pressure measurement gives inconvenience in precise measurement due to manually regulated pressures. In order to improve this inconvenience, the hydraulic valve meter was designed by using automatic design program CATIA and structural analysis of the designed hydraulic valve meter was conducted and internal water leaking, stress, strain and total deformation were obtained by applying three dimensional finite element code ANSYS. These results will be provided to develop new concepts of hydraulic valve meters as fundamental data.

In this paper, a high pressure cleaning machine in field was disassembled and measured in order to develop a highly improved pressure cleaner in performance and real configuration was modeled by using 3-D design program CATA V5. In addition, fluid analysis was conducted on the modeled high pressure cleaning machine by using ANSYS finite element analysis program and visualize the pressure changes of internal fluid flow was visualized. This result will be applied to a new designed high pressure cleaning machine in future.

A study on the weight reduction of a motor shaft in electric vehicle by using optimum design technique was carried out. The structural analysis of a motor shaft was performed by using ANSYS to investigate the structural safety. We also used HEEDS to find the optimal hollow shaft thickness. When the material of the hollow shaft is changed to SCM822H by using ANSYS 14.5 and HEEDS MDO, the weight could be reduced by about 53 % compared to the conventional solid one. From this study, the optimized dimensions of a hollow shaft were determined for light weight design.

In this study, the durability due to the fork shape of excavator bucket is investigated. The analysis is carried out by modelling the fork shape used in general. As the analysis condition, the pin is constrained as fixed support at the bucket and the load of 12000N is applied at the fork. As the study result, the maximum equivalent stresses at models 1 and 2 are shown as 56.895MPa and 54.722MPa respectively. Model 1 is shown to have the most deformation of 5.6686 mm among four models. Model 3 has the least deformation among four models and the maximum deformation of model 3 is shown as 4.948mm. The fatigue analyses are also carried out with three models. Each model shows the same fatigue lives under the identical fatigue loads. The damage part at each model is shown at the bucket pork or the pin connected with bucket. As this study result, the data is thought to contribute to the safety design at excavator bucket.
