The panels of the elevator are made of stainless steel and steel-based materials that are often used. When the elevator moves in an up and down motion, or when the door is opened or closed noise and vibration of the panel occurs. Therefore, in this study, we have studied the optimal design of the elevator car door to make the best design criteria to ensure the price competitiveness in accordance with new technical standards, by using the Catia stress analysis software, we have performed theoretical strength analysis and by carrying out test according to technical standards, we have acquired the experimental data and it has been analyzed. The results of this study are shown that the permanent deformation, the elastic deformation, and the safety performance of the car door are appropriate through the analysis of test results, and design factors meeting appraisal standards of the national technical standard have been obtained

In this study, new CVT system adapted for variable radius pulley is proposed to be available for pulley of CVT. Variable radius pulley consists of two disk and sliding pins joined by these disks. On account of phase difference of two disks, sliding pins move to radial direction and pitch diameter is varied. Therefore, change speed is accomplished by varying pitch diameter of pulley. CVT adapted for variable radius pulley is also performed with dynamometer test and axial distance variation. As a experimental result variable radius pulley can be alternative such as bicycle.

In this study, the strength property is investigated through structural and vibration analysis on the lead screw of height drive module for automotive power seat. The positions of applied loads are lowest, middle and highest on the model of lead screw in cases of 1, 2 and 3. Natural frequencies are examined about three kinds of models and critical frequencies are also checked by harmonic responses. Maximum deformations are shown as 0.033mm, 0.026mm and 0.551mm respectively in models of 1, 2 and 3. In case 3 at highest position, this strength becomes weakest by comparing with cases 2 and 3. By use of this analysis result, it is possible to design the model effectively applied at automotive safe driving.

A solar tracker is a device that orients a payloads can be toward the sun. Trackers are used to minimize the angle of incidence between the incoming sunlight and photovoltaic panel. This increases the amount of energy produced from a fixed amount of installed power generating capacity. In standard photovoltaic applications, it is estimated that trackers are used in at least 85% of commercial installations greater than 1MW from 2009 to 2012. This study is concerned about the structure design of a low coast and entry level dual axis solar tracker. This research purpose is to propose and verify a method to achieve higher product quality, lower costs, and far less physical testing. As a result of the new mechanism development, the volume of moving parts and the weight of main parts decreased by 46.8% and 20% respectively

The latest cultivation research and development of seeding technology was improved because the demand for direct planting increased. The Programmable Logic Controller (PLC) and position sensor are utilized to control the seed detection system. In this paper, of seed types, RPM (Revolution per minute) variations and hole size are considered to determine the capacity of seeder hopper to meet the needs of customer demand. These algorithms were composed of the process of seed monitoring and the compulsion opening system. The capacity of seeding is assumed to be 1.53kg(11.6 liters) of rice seed per 1.8km. Therefore, this detection system can be used to determine the capacity according to seed types, RPM and hole size.
