초록
In this study, a layout was designed to adjust the location of the LPG fuel tank by combining a Z-Spring and an Airbag in an LPG 1-ton truck air suspension assembly, and a structural analysis based on the finite element method was performed considering the load conditions of extreme situations based on the weight taken into account. The study was performed under a total load condition of 2.1 tons per axle with a safety factor of 2, and it was confirmed that the maximum stress value occurring in each part is within the yield strength value of the material. Through these results, it was confirmed that the designed LPG 1-ton truck air suspension assembly is a system with secured structural stability.
