摘　　要：基于ANSYS workbench 2020 R2,建立浮子流量计三维模型,通过等效静力法,对在地震、自重、内压等多种载荷组合作用下的核电厂浮子流量计进行抗震性能分析,并根据ASME规范和技术规格书的要求对计算结果进行评定。结果表明,应力和变形均在允许限值内,浮子流量计结构设计满足ASME规范和相应技术规格书的要求。Based on ANSYS workbench 2020 R2, a three-dimensional model of the float flowmeter was estab-lished. Through the equivalent static method, the seismic performance of the nuclear power plant float flowmeter under the combined action of earthquake, dead weight, internal pressure, etc., was analyzed, and the results were based on the ASME code. It shows that the average stress and de-formation are within the allowable range, and the structure design of the float flowmeter meets the requirements of the ASME code and the corresponding technical specifications.
