核安全级柴油发电机组的抗震试验

Anti-vibration test for nuclear plant security standard diesel generating sets

通过抗震试验,测定安全级设备的自振频率、振型、阻尼等振动参数和地震反应,考核设备的刚度(变形)、强度和位移,验证设备在地震载荷的作用下能否正常工作,保持其完整性和可运行性,以履行其安全功能。

By making the anti-vibration test, we mensurated the nuclear plant security standard equipments＇ self-vibration frequency, vibration type, damp and other vibration parameters and earthquake reaction. We also checked the rigidity （distortion）, intensity and displacement to verify if the equipment can work normally with earthquake load, which meant the equipment could keep whole system normally and perform ability, so that it can fulfill securing function.
