摘　　要：应用ANSYS分析核电厂应急柴油机主贮油罐的抗震能力,并采用RCC-M规范评定分析结果.对该设备的强度分析发现,最大应力值出现在主贮油罐筒体与小封头的连接处,而且改变小封头在筒体上的位置能够降低筒体与小封头连接处的最大应力值,从而实现结构的优化设计.结果表明对该设备的分析方法合理.The finite element analysis of anti-earthquake is performed using ANSYS on a main oil tank of an emergency diesel in a nuclear power plant. The analysis results are evaluated with the RCC-M criteria. It is found that the largest stress appears on the edge of the connection between the cylinder of main oil tank and the small head. The largest stress can be reduced by changing the position of the small head on the cylinder body. The results indicate that the analysis method is reasonable for the device.
