Recently, the demand of wire quality improvement has been increasing due to the development of the textile market, and the demand for round type flat wire having superior performance compared to the existing reed wire is also increasing greatly. The round wire requires equal spacing and precise alignment of the wire at reed knitting. So, there is a need for a method for measuring the flatness of Reed in real time. In this paper, it is shown how the contact and non - contact methods for the flatness of Reed used in a power loom are easy to measure in real - time process. The contact-type method provides excellent measurement accuracy and precision because it directly touches the object. The non-contact type does not touch the object, so it does not scratch the surface, and the result can be obtained faster than the contact type. Contact type measuring device was used as contact type and laser displacement sensor was used as non - contact type. It was confirmed that the measurement method using the laser displacement sensor (non-contact type) is suitable for the real time process.

In order to apply rotary atomizer to agricultural spraying system, the motor direct coupled rotary atomizer was proposed. The effect of operating conditions such as atomizing air flow rate, working fluid flow rate, and rotation speed of spinning cup on the atomization performance was investigated for the proposed direct coupled rotary atomizer. The motor speed was controlled in the range of 6,000 to 12,000 rpm using an alternating current transformer, and the atomizing air was supplied by the compressor. In this study, LDPA was used to analyze the spray characteristics of the rotary atomizer. The representative particle diameters of D10, SMD, MMD, D90, and DMax tended to decrease as the atomizing air flow rate and the motor speed increased, but increased as the working fluid flow rate increased. Also, SMD was found to be influenced by order of atomizing air flow rate> motor speed> working fluid flow rate, and DMax was influenced by order of operating fluid supply> motor speed> atomizing air flow rate.

It is well-known that the primary role of a vehicle exhaust system is to reduce the exhaust emissions and noise caused by a running vehicle. However, as vehicle exhaust systems are being evaluated and improved in various ways to satisfy consumer needs, technologies for reducing noise and vibration are significantly being developed. The biggest challenge in designing an exhaust system is generating the optimal back pressure and flow velocity for a running vehicle, thereby maximizing the performance, while simultaneously reducing the noise caused by the exhaust emissions. In this study, we designed the junction chamber shapes of various exhaust systems, which are applicable to V6 and above engines, and conducted a CFD analysis of the exhaust gas flowing through an exhaust pipe. In addition, we precisely measured the noise and vibration caused by a vehicle and analyzed the correlation.

This study investigates the noise characteristics of small DC motors and applies them to the production line of small DC motors to qualify. Because currently the noise and vibration are greatly reduced due to vibration reduction technology and sound insulation technology of engine and transmission development. For this reason, the noise and vibration problems of various small DC motors that have not been heard before are emerging. For this purpose, noise characteristics of good and bad products of company A and B which are most used at present are analyzed and noise characteristics are investigated.
