Finite element analysis of the tank semi-trailer‘s frame on road irregularities and liquid sloshing conditions

Abstract

The strict requirements in order to optimize the fuel consumption of vehicles thus reducing the emission of greenhouse gases, force manufacturers focus on structural optimization during the development of new type prototypes. The stresses and deformations of the main member of frame and tank which occur during operation under cyclic loads were researched. The review of scientific articles that examine the construction of truck semi-trailer frames and their research, the use of new materials in the automotive industry, and the phenomenon of liquid sloshing and researches done on this subject. The dual-phase 1.4162 (DUPLEX) steel was used for tank while the frame structure made of 1.4404 (316L) stainless steel, 1.4162 (DUPLEX) dual-phase steel, 6063-T6 aluminum alloy and S235JR black steel. The research methodology has been developed to assess the stresses, strains and critical points in the structure where is a high probability of cracking during operation. Results were gathered using ANSYS software and the most suitable material for the main member of frame was recommended.
