In this study, we will try to develop the 3D automatic design program of limit gauge. When users, who Have some mechanical information input some date, they can do 3D-modeling easily like expert. This is one of the merit in automatic design program and the automatic design program can compare the limit gauge made in this study with processed the bolt and nut model. This demonstrates the effective value of automatic design model. Limits gauge of sort divide into ring gauge of measuring bolt and pin gauge of measuring nut. The new automatic design program follows the KS

This study is an investigation far the Am optimum design using FEA. We write out program which express ADS perfectly and reduce the required time far correcting of model to the minion in solution md manufacture result. We complete algorithm which can plan optimum forming of model by feedback error information in CAE. Then we contract model by feedbback date obtaining in solution process, repeat course following stress solution again iud do modeling rachet wheel for optimum forming. That is our aim. In cachet wheel, greatest equivalence strss originates in key groove comer and KS standard is proved the design far security.

In this study, we try to develop the 3D automatic design program of screw thread limit gauge. When users, who have some mechanical information, input some date, they can do 3D-modeling easily like expert. This is one of the merit in automatic design program and the automatic design program can compare screw thread limit gauge made in this study with processed the bolt and nut model. This demonstrates the effective value of automatic design model. Screw thread limit gauge of sort divide into ring gauge of measuring bolt and pin gauge of measuring nut. The new created automatic design program follows the KS.

This study is an investigation for the ADS optimum design by using FEA. We write out program which express ADS perfectly and reduce the required time for correcting of model to the minimum in solution and manufacture result. We complete algorithm which can plan optimum forming of model by feedback error information in CAE. Then we correct model by feedback date obtaining in solution process, repeat course following stress solution again and do modeling rachet wheel for optimum forming. That is our aim. In rachet wheel, greatest equivalence stress originates in key groove corner and KS standard is proved the design for security.

This study is an introduction of ADS in which we have written out programs which can design three-dimensional machine parts and reduce the required time for design them comparing with other CADs. Among the machine parts, screws are commonly used in joining one part to another because of easy handing but welding and rivet are used to join permanently them even thought hard operation. Consequently, we have developed the screw fer permanent fixing using stairs type screw threads, which is considered as the main machine parts in joining. For that, we designed permanent fastened screws according to the different rotation angle using VisualLISP and transferred it to ANSYS, structural solution program, to find out allowance load, maximum equivalent stress and where it occur.

ADS-B(Automatic Dependent Surveillance-Broadcast) has been recognized as a key component of Surveillance and ATM in CNS/ATM System. In addition to providing surveillance for air traffic control(ATC), ADS-B also supports airborne applications such as enhanced traffic situational awareness through the display of other aircraft to pilots and flight crew. It provides the real-time and same air traffic information to pilots in the aircraft cockpit, air traffic controllers in tower and surface vehicles on the ground at the same time. Aircraft Cockpit Display Unit will display the given information precisely and accurately. This paper describes progress in the development of a Cockpit Display with ADS-B data that enable pilots to acquire, verify and maintain pre-defined spacing intervals from other aircraft for general aviation and small regional aircraft. The designed display provides analogous information in the form of traffic position, range, and ground speed, etc.

새로운 개념의 항행 시스템인 CNS/ATM(Communication Navigation Surveillance/Air Traffic Management)의 등장에 따라 항공 감시분야에서는 ADS-B(Automatic Dependent Surveillance-Broadcast) 시스템이 구축되고 있다. FIS-B(Flight Information Services-Broadcast)는 ADS-B의 핵심 요소 중의 하나로 기상정보를 비롯하여 각종 운항정보를 항공기에 제공하는 매우 중요한 역할을 한다. 본 논문에서는 FIS-B 표준을 검토하여 성능 요구조건을 분석하였고, 이를 바탕으로 FIS-B를 설계 및 구현하였다. 모의실험을 통해 FIS-B에 대한 성능을 확인하였으며, 본 연구는 향후 FIS-B의 연구 자료로써 유용하게 활용될 수 있을 것이다.

This study developed Gear Automatic Design Program that users with the basic knowledge about mechanical engineering can easily model spur gears and helical gears. The Gear Automatic Design Program used Visual LISP which is an user program based on Auto CAD and made it model the gears with involute tooth by the exact mathematic definition. Also, to verify these, the reliability was secured by comparing it with a gear generated in commercial software. And we will develop nitrocarburising process and solve problems which had been caused of SCM440's dimensional changing.
