摘要
对正常工作状态的某风机基础进行了动力测试,采集了控制点的加速度、位移时程,并对其进行了频谱等相关动力分析,全面地了解了风机基础结构自振频率和阻尼比等动力特性的变化规律,对正常使用过程中各点的温度进行了检测,为风机基础的设计提供了依据。
A blower base was investigated by a dynamic test under normal working conditions.The acceleration and displacement time-history of control points were collected and dynamic analysis such as spectrum analysis was carried out.The change of dynamic characteristics including natural frequency and damping ratio were fully obtained and temperatures of all the points in normal operation were measured.The design basis of blower base is provided.
