본 발명품은 Arduino UNO를 사용하여 설계한 바텐딩 제어 시스템을 채용한 것으로서 주요 기능은 전자밸브와 펌프의 공동 작동을 통해 모든 음료의 토핑 재료를 정확하게 추출하여 혼합하여 생산하며, 수출 상단에는 LED와 음향을 장착하여 시각 및 청각 효과를 더욱 좋게 하였으며, 바텐더의 도움 없이도 가정에서 사용할 수 있다. With the development of intelligent electronic technology, newly smart machine technology comes true. This paper mainly use Arduino UNO to design a control system of the current blender, the main function of the system is to accurately control the ingredient of each drink through the peristaltic pump control circuit and relay circuit, the wine is modulated by the mixing mechanism, For better visual and acoustic effects, LED and sound are added above the reclaiming port. Through the order system to select drinks without the intervention of the staff, the equipment is in the state of no sales.

Research on the cone angle and clearance of main pump seal
Wang Heshun,Zhu Weibing,Huang Zepei,Zhang Chening,Zhang Junkai 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.7
For better film characteristics of the main pump seal (MPS), a theoretical calculation model was proposed based on the Reynolds equation. A case study with defined MPS was carried out, film stiffness was taken as the basic constraint condition, and the cone angle andclearance are two optimization targets. When the film stiffness reaches a maximum, the corresponding cone angle and clearance is theoptimal value. The results show that: (1) film stiffness increased and decreased with clearance and cone angle, respectively; (2) the optionalclearance was determined to be within a range of 2~8 μm at a cone angle of between 0.1~1.2'; (3) the maximum of film stiffness isinversely proportional to the cone angle (Clearance) approximately under the clearance (Cone angle) is fixed; (4) leakage is directly proportionalto the clearance to power three, and the clearance has greater influence on the amount of leakage than the cone angle. Theseresults provide a reliable theoretical justification for MPS-based designs including optimization method. It therefore forms a fundamentalbase for research and practical application.

In this paper, a probabilistic design optimization method for wind power gear drive system has been put forward based on the dynamic reliability. A pure torsional dynamic model of 1.5 MW wind turbine gear transmission system is developed which is based on lumped parameter method with incorporation of gear meshing stiffness and transmission error. By taking the wind load and the gear parameters as random variables, the variation in dynamic reliability of the system with time is obtained. The probabilistic optimization design model of the wind turbine gear transmission system with minimum displacement and volume is built. The parameters affecting the dynamic performance and reliability are taken as optimization design variables. The system reliability, the effects of random parameters on the reliability, the normal meshing condition and gear strength are taken as constraint conditions. We choose the gear transmission system of a 1.5 MW wind turbine for the system optimization and experimental verification. The results show that the system optimization based on dynamic reliability can reduce the volume of the system by 17.94 % and the system reliability is also guaranteed. Moreover, the vibration of each component of the system is reduced which is beneficial for smooth operation of the gear transmission system of wind turbine.
