Abstract

A study is made to enhance the performance of the sub frame in YJ3128 type dump truck by reducing the vibration, weight and provide uniform load in static condition. A three different case studies has been made by modeling the sub frame with three different cross section namely C, I and Rectangular sections. The work is performed by varying the position of the cross members in the sub frame and validate through FEM approach. The dimension and material for this study is taken from the existing model of YJ3128 type dump truck. Based on the comparison of theoretical and analytical results of max principal stress and deflection, the optimized sub frame has been identified. It is mainly utilized in carrying the power train unit of the heavy duty vehicle that are used in mining's, construction sites and highways for transporting sands and gravels.
