A steering knuckle for a car is a key part of a corner module and is a functional part connected to steering, suspension, and braking devices. Steering knuckles are used for various types of forging and machining methods such as casting forging, aluminum forging, etc. to perform productivity and quality. Therefore, in this study, we study about the development of the overall design of the steering knuckle in the production and supply of the steering knuckle for the product processing method, quality, assembly inspection, etc. through the modeling and analysis of the steering knuckle.

There are many studies to extend the distance traveled by electric vehicles. However, much research has been done to increase the capacity of the battery. In this study, some engines for power generation, in which a battery is charged with energy by mounting a small internal combustion engine in which an engine is mounted in an electric vehicle and the battery is charged with energy, are being studied. Therefore, since such an engine is operated at a high load, the camshaft and the camshaft are emphasized to have high load strength and durability to withstand fatigue.

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,

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.

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, as the use of automatic transmissions increases, attention is focused on remanufacturing of automatic transmissions. The automatic transmission includes a clutch, a brake, a planetary gear, and a planetary gear unit, which are power transmission devices, an oil pump and a valve body which are lubricating devices, a controller which is an electronic control device, sensors and switches which input and output the controller. In particular, this study is a basic study for remanufacturing such as disassembling, assembling, and inspecting element parts for manufacturing valve body material which is a core part of automatic transmission.
