摘要
针对保温罐箱容积小、卸料口处三角筋易出现裂纹等问题,参照ASME和GB150的相关规定,在考虑工艺减薄量与腐蚀余量等因素的基础上开发了新型大容积罐箱,并对卸料口处结构进行了改进。利用ANSYS对IMDG中最危险的向前冲击工况进行分析,并通过试验得到该工况下新型大容积罐箱的最大变形量与最大应力。分析结果表明:新型大容积罐箱结构强度满足设计要求。
To the problems of small volume, triangle rib cracks in discharge opening in heat preservation tank, based on the standard of ASME and GB150, a new type of large tank was developed, and the thinning process and corrosion allowance were taken into consideration. The structure and type of triangular rib were modified. By using ANSYS, the dangerous case of forward and backward impact of IMDG was analyzed, and experiment was done to verify the maximum deformation and stress. The results show that the structure strength of the tank can meet the design requirement.
