【摘要】 基于对热模锻压力机车间的振动实测 ,对热模锻压力机激起的地面振动的传播与衰减作了更切近实际的分析 ,得出了热模锻压力机引起的地面水平向振动不可忽略 ;水平向振动与竖向振动衰减快慢不同 ,难以用同一衰减公式表示等有意义的结论。更多还原

【Abstract】 Based on a field measurement of the vibration in hot forging press workshop,a realistic analysis is made on propagation and attenuation of the ground vibration.It is shown that the horizontal vibration caused by the hot forging press can not be negligible.The attenuation rate of horizontal vibration is different from that of vertical vibration and could not be expressed by using a same formula.更多还原
