Beam, Tank semi-trailer, FEM


This paper presents a study on loading platform beam utilized for tank semi-trailers, short truck chassis structure, and the setup design of tank stand holder would not mount with bracket. There is the platform beam form that is made of H-BEAM steel, estimated at 300 x 150 x 6.5 mm. And loading platform beams utilizing welded steel plates, size 300 x 150 mm. They were examined and analyzed by finite element method in order to determine the factor of safety whereas carrying the stack. The results showed that H-BEAM loading platform beams have high strength and safety value of 3. However, due to its high weight of 181 kg, hence it is not appropriate for the development of a lightweight chassis structure. On the other hand, the truck loading platform beams utilizing welded steel plates from 18 distinctive thickness simulations, it is illustrated that Beam 18 incorporates a maximum weight of 134 kg with a safety value of 3.2, which is comparable to the H-BEAM loading platform beam, and there are 2 types that should not be utilized because the beam parts are too thin. As a result, the factor of safety is less than 2.
