Integration Stress Analysis and Structure Assessment of Large LPG Tank Trailer

Though establishing computer simulation model in this paper, integration stress analysis of large LPG tank trailer is carried out with finite element method and the stress distribution of main structure members in critical range is gained. Detail analysis and evaluations for tank trailer's integral function are made for some local structure such as reinforcement ring, anti-wave baffles, and support structure of tanks. Some structure design suggestions are proposed in this paper according to the function analysis.
