摘　　要：对某型加固计算机的随机振动进行有限元分析和PSD响应测试,给出该型加固计算机随机振动有限元分析中连接刚度和接触阻尼的等效处理方法并与测试对比,结果表明处理的结果与测试数据的吻合程度较高,验证了连接刚度和接触阻尼对加固计算机随机振动影响的预测,为各型加固计算机的随机振动有限元分析提供了参考依据。The finite element analysis and power spectral density response test of random vibration of a reinforced computer were carried out.By comparing the calculation and test data,the preliminary equivalent treatment of connection stiffness and contact damping in random vibration finite element analysis of the reinforced computer were given.The results show that the adjusted calculation agrees well with the test data,which can reflect the influence of connection stiffness and contact damping on the random vibration of the reinforced computer,and provide a reference for the random vibration finite element analysis of various types of reinforced computer.
