Abstract

The Development of automotive todays is very fast because every single year there is always something new. This research aims to design fuel-efficient vehicles and environmentally friendly, especially the transmission is driven by an electric motor that used a chain sprocket transmission system is applied to the electric gocart. From the results of this research shows that the transmission can be used on a simple electric gocart transmission system chain sprocket is roll type single line, which consists of two sprocket and chain on rotation 1 750 rpm and 2 hp motor power. Dimensions obtained by the small sprocket diameter 35 mm with a number of teeth 9 pieces, large sprocket diameter 250 mm with a number of teeth 62 fruit and chain length of 1,243 mm at a distance of 381 mm spindle axis. Keywords: Design, Transmission Chain, Electric Gocart

Abstract

The crack is one of the frequent problems in engineering field. It effectively cause the component become fail. Therefore predicting crack growth is very important. Prediction was applied, so crack can be prognosed. In order to prevent failure in a component, crack prognostics have applied. The aim of this research is developing of Grey Model as a predictor, and application of developed Grey Model on crack growth prediction. The crack growth data acquired from experimental files were employed for evaluating the proposed method. A modification has made to improve the accuracy of prediction. In addition, error parameter has involved for evaluating the predicting performance.The methodology of this paper consists of five stages. That are theoretical study, simulation of basic grey model, background value modification, simulation of modified grey model, and application of modified grey model.The result shown there are decrease of error values on the prediction. The reduction of error values of three prediction data are 14,07 %, 4,01 %, and 6,93 % respectively. Thus, the development of grey model for crack growth prognostic has successfully made. Keyword: Crack, Prognostics, Grey Model, Prediction Method

Abstract

Stirling engine is a heat engine that is driven by compression cycle and expansion of the working fluid in the form of gas. At different temperatures there will be a pressure difference which causes changes in heat energy to mechanical energy. Mechanical energy can be used to drive a water pump. This study aims to design a solar power Stirling beta engine to drive a water pump. There are six stages in this research. The first step is literature study. The second step is data collection. The third step is the calculation of the initial data. The fourth step is determining the initial dimensions. The fifth step is designing. The final step is a conclusion. Through this research, the Stirling Beta solar power has been successfully designed to drive the water pump. The design results can be described in five parts. The first part is the centralized temperature generated from a parabolic mirror with a diameter of 800 mm ranging from 937 K. The second part is the resulting cycle pressure of 1.79 bar. The third part is, at 3000 rpm, the Stirling engine producing a power of 496,6 Watt.. The fourth part is the torque produced by the engine of 30.07 Nm. In the last section, the dimensions of the Stirling engine design are 524 mm long, 167 mm wide and 200 mm high.Keywords: Stirling Beta, Solar Power, Water Pump
