Assembly of automobile interior materials is very important for assembly and inspection such as sensitivity and noise reduction. Particularly, since assembling parts of automobile interior parts is manually assembled by a worker, a claim due to poor assembly sometimes occurs. In addition, as the labor cost rises, automobile assembly line adopts automatic assembly device as the concept of smart factory in assembly process. Therefore, in this study, we intend to develop automatic assembly device of the door trim for reducing the field claim, improving the productivity, and reducing the assembly failure.
Recently, automobile washing methods have been carried out using steam of high temperature and high pressure instead of water. Therefore, it is necessary to secure the structural stability of the steam tank. In this study, it is necessary to reduce the weight of the steam tank by reducing the thickness of the existing steam tank by about 25%. The safety of the product design was verified through simulation to ensure the robustness of the product by securing the structural stability and fatigue analysis at high temperature and pressure of the steam tank according to the weight reduction. For newly developed products compared to existing models.
In this study, temperature and pressure of guided wave radar products are transmitted at high temperature and high pressure. In the case of transmission of temperature pressure, high temperature and high pressure steam leak from the guide rod part to the atmosphere causes the failure. Therefore, in this study, structural analysis and thermal flow analysis of the product are performed to identify the problem of the product, so as to prevent leakage in the product development by grasping the cause of the leakage of the product. In this study, if the method of assembling the lower end of the piston rod and the gasket is changed from line contact to face contact,
In recent years, the regulation of exhaust gas of automobiles has been strengthened, and various high-tech technologies have been applied to cope with exhaust gas regulations. Especially, in case of gasoline vehicles, by injecting gasoline direct injection, a large amount of carbon deposits are adsorbed in intake / exhaust valves and combustion chambers, Which is a cause of combustion. Therefore, in this study, we developed the cleaning liquid and related special tools to remove carbon deposits in the combustion chamber, and developed the cleaning process of the combustion chamber and tried to understand the effect on the engine performance improvement. In order to prevent the release of heavy metals after burning, the cleaning effect of the cleaning liquid was investigated by temperature and the influence of the knocking of the engine on the cleaning performance.
This study is intended to secure seolge and structural strength of the suspension as necessary amphibious boat amphibious facilitate a possible amphibious boat 7m parenting class. Developed a technique for mounting a three-wheel drive track traveling device to medium-sized vessels, and the control device in order to improve the efficiency of the safety and operation of this device, the braking device of the land driving, the steering apparatus and the linear adapted to install the device development and installation of the wheels on the bottom, leaving space travel wheel award during lift pockets (wheel pocket) analyzed the impact of the ship resistance and stability, and tried to improve the problem.
This study will develop a small ship, boat, It is available a versatile system to rock like a shower, as well as drinking water by desalination of sea water just offshore yachts, etc. to be applied to their own country.
In this design the element technology development part design and the point in the system was designed to be compactly mounted to a boat or the like is applicable. To work in the maritime industry, as more and more leisure development becomes a sail to load large amounts of water before departure, such as the drinking water is to give an adverse effect on fuel consumption with the increase gigyul eojim and the weight of the hull during loading increased due to set sail. Therefore, the present study was to compensate for this disadvantage by designing the first time in Korea Development wishes to contribute to import substitution effects were developed with an emphasis on practical application.
This study is Performance Improvement of Hot Water Panel to Energy Reducing. Hot Water Panel is two kinds of Wet and Dry Type. This panels are very important to reduce energy saving, for example TOE, energy savings. The effecting elements to performance improvement of hot water panel are panel characteristics and manufactured types. This study used dry type of hot water. The dry type acquired 56% energy saving comparison to wet type.
AbstraThis study on the High Vpltage Ionizer for Automotive to reducing of an Electrode heat deterioration.
