Analisis Tegangan Frame Support Kingpin Pada Redesign Struktur Sasis Lowbed Truck Dengan Metode Elemen Hingga

Abstract

The development of the transportation body industry in this modern era has grown rapidly, proportional to the demand for logistics and distribution activities to various points. Lowbed truck is one of the vehicles that can be used in the distribution of heavy equipment. In this research, it is carried out as a 120 Ton lowbed truck product development that functions as a heavy equipment transporter from one place to another. The problem of lowbed trucks in truck fabrication companies or car bodies, the chassis structure is damaged in the kingpin support framesection due to deformation due to excessive stress. Therefore, in this study, a redesign of the 120 Ton lowbed truck chassis 3D model was made in the kingpin support framesection and analyzed using software with the finite element method. The simulation results obtained a maximum stress value of 624.26 MPa for lowbed trucks with plate model kingpin support frames and for lowbed trucks with beam model kingpin support frames have a maximum stress value of 330.16 MPa. So that the design of the support kingpin plate and beam models can be used as a lowbed truck and carry a load of 120 tons.
