为了克服联合机器基础割开计算的缺点,本文提出了一种地基计算模型,即在计算中采用耦合地基刚度。按本文的多自由度弹性计算模型进行整体分析,能较好地符合联合机器基础振动反应的变化规律。
In order to overcome the shortcomings of the joint-machine-based cut-off calculation, a ground-based calculation model is proposed in this paper. The coupling ground stiffness is used in the calculation. According to the overall analysis of the multi-degree-of-freedom elastic calculation model in this paper, the variation law of the vibration response of the combined machine foundation can be well complied with.
