Analysis of Structural Strength and Fatigue Life of Hazardous Chemical Tank Truck

In this paper, the safety and durability of the structure of the hazardous chemical tanker is evaluated by analyzing the strength and fatigue life of the tank body. By using finite element analysis software, the stress and deformation of key components such as front vessel head, wave plates and rear vesse head of tank truck are analyzed in detail, and the fatigue life under impact load is calculated. The greatest stress is located at the connection between the vessel head and the cylinder, and the front vessel head is greater. The maximum fatigue damage occurred on the structure of the wave plate.
