This paper deals with energy storage system for saving the energy of RTGC(rubber tired gantry crane). Advantage and disadvantage of battery, super-capacitor, and flywheel as an energy storage system were surveyed. Even if a flywheel energy storage system includes some problems such as manufacturing technique and high price, it is surveyed with a promising energy storage system In addition, RTGCs using battery or flywheel as the energy storage system were quantitatively presented through a survey of literatures. It was found that the both RTGC with those systems can reduced the waste of energy.

본 논문은 현대자동차에서 개발중인 이중질량플라이휠(DMFW)의 구조적, 열적 특성을 FEM code를 사용하여 평가하였다. DMFW의 몇몇 단품들은 SAE와 RICARDO에서 제시하는 평가기준을 만족시키기 위해서 일부 수정되었으며, 새로운 DMFW 시스템을 개발하는데 있어서 FEM을 사용한 방법은 매우 유용함을 알 수 있다.

The conventional serial UPS using battery energy storage unit is almost universally used. Despite its common usage, the conventional UPS has a number of disadvantages which may be effectively overcome by the application of flywheel energy storage unit. This paper proposes a new type of parallel processing UPS using flywheel energy storage unit, which has the feature of high power, long life, and high efficiency.
