The Fourier series approach (FSA) is adopted and extended to consider frequency-dependent aerodynamic admittance function and self-excited force. This adopted method is verified by comparing with a conventional method, the rational function approach (RFA). The admittance function of a bridge deck is extracted from experiments. The admittance function measured from the experiment showed difference with theoretical Sears function for airfoil cross-sections. This measured aerodynamic admittance function is approximated successfully by FSA. The introduced scheme is applied to the full FEM model of a cable-stayed bridge. Comparison of the response from the Sears function and experimentally extracted admittance function is dis cussed.1. Introduction 1 2. Fourier Series Approach for Aerodynamic Admittance Function 3 3.

    A Study on the Torsional Vibration Control for Propulsion Shafting System with Slow Steaming on 2-Stroke Main Engine

    Currently, there are two highly controversial topics in ship industry, which are the reducing the cost of oil used and decreasing the emission of chemical gas through efficient energy consumption with technological innovation. This paradigm shift caused the ship industries to become involved in green shipping. This phenomenon is not only visible in domestic markets but also in international markets as well. In order to reduce emission gases and operating expenses, increasing number of newly constructed ships are integrating the slow steaming system. Slow steaming system restricts the air flow of compressor and the turbine to increase the efficiency of turbocharger in the operating range of a main engine with two or more turbocharger. However, fuel saving engines equipped with slow steaming system are causing the harmful vibration on the exhaust gas manifold of the main engine. Furthermore, if additional torsional stress and amplitude of the shafts exceed the limit value regulated by classes with in the operating range of the shaft’s torsional vibration exceeds the limitation within the normal operating range of the engine, it could result in fatigue of the shaft and accelerate the wear in the gear system it may be caused to broke the shafts. Since shaft vibration also causes vibrations such as local vibration of the engine room and hull vibration, it is essential to limit the revolution of the shaft or limit the additional torsional stress in the design stage. There are several ways to control torsional vibration, which are controlling the exciting force, avoiding the critical revolution from operating area, and reducing the response level of the vibration. Changing the ignition sequence of the engine or changing the angle of the crank to unequal interval are mostly used method to control exciting force changing ignition sequence helps to control torsional vibration from critical revolution, and changing the angle of the crank to unequal interval helps to control torsional vibration of main critical revolution or particular sub-main revolution. This method should consider both the engine’s revolution and engine’s structural vibration. Next, increasing the mass moment of inertia of tuning/turning wheel allows to avoid the critical revolution from operating area. Also, changing the stiffness by changing the diameter of the counter shaft or propeller shaft helps to avoid the critical revolution. To reduce the response level of the vibration, mostly used method is to use a torsional vibration damper and increase the damping energy to control additional torsional stress. In conclusion, onboard vibration was measured by analytical analysis of vibration from shafts torsional vibration response and vibration from engine’s major component exhaust manifold that changed exciting force in ship’s main engine due to Integration of Slow Steaming. As a result, the integration of slow steaming causes the increase of exciting force in the main engine and affects the shaft’s torsional vibration and hull vibration. Thus, pre-inspection is crucial and countermeasures in case of resonance is essential.제1μž₯ μ„œ λ‘  1.1 연ꡬ λ°°κ²½ 및 λͺ©μ  1.2 연ꡬ λ‚΄μš© 및 ꡬ성 제2μž₯ Slow steaming이 적용된 κΈ°κ΄€μΆ•κ³„μ˜ 비틀림진동 기진λ ₯ 해석 2.1 Slow steaming이 적용된 κΈ°κ΄€μ˜ 비틀림진동 이둠적 κ³ μ°° 2.2 κ³ΌκΈ‰κΈ° 차단 μƒνƒœλ„ 2.3 κ³ΌκΈ‰κΈ° 차단이 적용된 κΈ°κ΄€μ˜ 기진λ ₯ 해석 제3μž₯ Slow steaming이 적용된 κΈ°κ΄€μΆ•κ³„μ˜ 비틀림진동 해석 3.1 12RTA96C-B 기관을 κ°–λŠ” μΆ”μ§„μΆ•κ³„μ˜ 비틀림진동 해석 3.1.1 λΉ„ν‹€λ¦Ό μžμœ μ§„λ™ 해석 3.1.2 λΉ„ν‹€λ¦Ό κ°•μ œμ§„λ™ 해석 3.2 12RTA96C-B 기관을 κ°–λŠ” μΆ”μ§„μΆ•κ³„μ˜ 비틀림진동 계츑 3.3 8RT-flex68T-D 기관을 κ°–λŠ” μΆ”μ§„μΆ•κ³„μ˜ 비틀림진동 해석 3.3.1 λΉ„ν‹€λ¦Ό μžμœ μ§„λ™ 해석 3.3.2 λΉ„ν‹€λ¦Ό κ°•μ œμ§„λ™ 해석 제4μž₯ κ²° λ‘  μ°Έ κ³  λ¬Έ

However, the relationship between metabolic syndrome and ferritin has not been fully understood. We defined the metabolic syndrome, according to the ATP? guideline and Korean waist circumference (male: 90cm > , female: 80cm > ). The purpose of this study was to investigate the risk factors of metabolic syndrome in Korean adults.A total of 2.969(Males 1,876, Females 1,903) subjects aged from 20 to 70years who visited Friendodtor Hospital health care system Center between January 2002 and December 2005 were studied.We excluded those who were not available for physical parameters andblood test results. We estimated the prevalence of the metabolic syndrome according to the ATP? diagnostic guideline. Waist circumference, HDL- cholesterol, triglyceride, diabetes medication, hypertension medication, and age, were investigated. Multiple logistic regression analysis was conducted to identity correlation between each factors and elevated Ferritin value.In men, with mean increase Ferritin(?195 ng/mL) there was a statisticallysignificant positive correlation between metabolic syndrome and Ferritin. A significant negative correlation was found between CRP and triglyceride, hypertension and Ferritin. In women there was a significant positive correlation between metabolic syndrome, diabetes mellitus and Ferritin.In this study, elevated serum Ferritin concentration was associated with an increased risk of triglyceride for men and metabolic syndrome for women.Therefore, this study suggests that Ferritin is an important predictor for metabolic syndrome.ope
