LPG罐车罐体应力分析与结构设计评价

Integration Stress Analysis and Structure Assessment of Large LPG TankTrailer

通过建立计算机分析模型,对某大型LPG半挂罐车的罐体进行了整体应力分析,用有限元方法对罐体进行了应力分布计算,得到了罐体关键部位的应力结果。针对影响罐车整体性能的加强圈、防波板、罐体支撑等局部结构进行了分析和评估,提出了对该结构设计原则和建议。

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.
