阀门核级气动执行机构抗震分析

摘要

Introduces the nuclear grade pneumatic actuators seismic analysis method, discusses the stress evaluation criterion, and verify the pneumatic actuators the rationality of the seismic performance. This method can improve equipment seismic evaluation test passing rate, also can be as a qualification basis for pneumatic actuator series products before earthquake evaluation test according to the appraisal.%介绍了核级气动执行机构抗震分析的方法，论述了应力评定准则，验证了气动执行机构抗震性能的合理性。此分析法可提高设备地震鉴定试验的通过率，亦可作为气动执行机构系列产品中未进行地震鉴定试验产品的鉴定依据。
