Abstract

This paper presents the analysis of mini excavator excava 50 with a focus on the boom component. The boom component is a component that has a heavy workload. The material used in the existing design is SM490A. The results of the analysis are still not safe because allowable stress is less than working stress. The material in the existing design was replaced with Hardox 400. The design is declared safe. However, the costs of the product have increased because Hardox 400 materials are more expensive than SM490A. To reduce the costs of the product, design improvement is needed to optimize the use of material. The design improvement method that uses in this study is according the optimization method, that is sizing and shape optimization. After improvement the design, to predict how long the boom component can be used, fatigue life prediction is calculated using Goodman’s theory

Abstract

Gear is one of the most important part of power transmission system in a vehicle, and as the time goes by there possibly some failure happened on the gears. However, there is no information provided by car manufacturer regarding the life and the material of the gears. This report presents the analysis of the planetary gear used in Toyota Rush AT year made of 2012. The objectives of the research are: to study the planetary gear mechanism and how it works; to analyze the force and stress acting on the gears; and to select a suitable gear material that can withstand against the loads that happen on the gear. The research methodology is started with finding the gear dimension and gear ratio. The force acting on gear is calculated based on the torque and rotation speed provided in car specification. Then the selection material is carried out based on the amount of stress applied on the gear teeth that were calculated using AGMA standard formulation. Finally, the fatigue life prediction of the gears is calculated based on the previous stress acting on the gears. The calculation result suggested AISI 1050 steel as the selected gear material that can carry the bending stress of 476 MPa and categorized as low to high fatigue cycle.
