Abstract

The flywheel as a mechanical battery is an energy storage device that is superior in terms of charging and discharging compared to other energy storage devices. In this research the dimensions of the mechanical battery are design in a such a way as to make it easier to use in daily life. On other side the mechanical battery is designed using permanent magnet bearing in the hope that it can minimize the occurance of frictionthat can reduce the power of the battery.The research was made in a Design and ConstructionLaboratory, Majoring in Mechanical Engineering UNSRAT. In this research the shaft material used is carboon steel type S30C which is heat treat with normalization. The shaft diameter is obtained 18 mm and flywheel diameter is 100 mm. Magnet capacity on the shaft as many as 28 magnets on each ring. So the total magnet on the shaft are 224 magnets. Aside on that in this research the diameter of the bearing is 30 mm with magnet capacity is 40 magnets on each ring. So the total magnet on the bearing are 320 magnets.The final result of the mechanical battery dimensions is 110×120×105 mm. the magnitude of the magnetic support force on each ring is 900 gr with the total bearing support force is 7,2 kg. The maximum torque that can be held is 4574 kg.mm Keyword : Mechanical Battery, Dimensions, Magnetic Bearing

Abstract

Object such as Fly Wheel, it is bound to have natural frequency as one of it is vibration parameter. If excitation is applied at the same frequency as natural frequency, then resonance will occur. As the result, excess deformation on the structure can occur. In this research, the natural frequency from the Fly Wheel was calculated. The calculation was conducted with the help of Finite Element on a software. Followed with the calculation of the working frequency range and structure deformation as a result of the vibration that occurred. The deformation calculation was conducted because deformation will effect the size (dimension) between the wheel and the housing.  However, the simulation that was conducted only on the first five vibration mode. This Research is consisted of four stages. The four stages are literature study, fn analysis of a basic road, preliminary measurement mechanical battery and fn analysis of the mechanical battery. Preliminary measurement was conducted because the mechanical battery that was analysed is already constructed in Construction Laboratory, Department of Mechanical Engineering, University of Sam Ratulangi.The Result of the simulation indicated that five vibration mode occurred on these spinning frequency are 32.21 Hz, 88.71 Hz, 173.93 Hz, 287.48 Hz, and 429.32 Hz. Followed, the biggest working range are between vibration mode two to three. Finally, deformation that effected the size between Fly Wheel and housing bearing it is on two, three and five.Key Words: Fly Wheel, Natural Frequency, Vibration Simulation with Software.
