摘要
文章总结了埋地储罐结构设计方法,分析了其受力特点,针对储罐的特殊工况提出了采用ANSYS软件进行数值模拟的方法。结合具体设计实例,介绍了在结构设计之后,利用ANSYS软件进行建模加载计算得出储罐在覆土外压作用下的变形及应力分布规律的方法。对比分析理论计算与数值模拟结果,验证了数值模拟结果的正确性,指出常规稳定性设计的不合理之处,说明了数值模拟作为储罐结构设计的参考和补充的必要性。
In this paper,the structural design methods for buried tank are summarized,the stress characteristics are analyzed,and the numerical simulation method by ANSYS software is proposed according to special working conditions of the tank. In view of a specific tank design instance,the numerical model is established and the deformation and stress of the tank are calculated by ANSYS software after the structural design done. Comparative analyses on the theoretical calculation results and the numerical simulation results are conducted to verify the correctness of the numerical simulation results,and the unreasonable points in traditional stability design are pointed out,which prove the importance of the numerical simulation as reference and supplement for structural design of buried tank.
