摘要
针对实际工程中的动力设备,采用DYNA5计算设备-基础-地基工作体系在不同工作频率下的刚度和阻尼,应用STAAD.Pro有限元分析软件建立了合理的计算模型,并对其进行模态分析、动刚度及强迫振动响应分析,计算结果满足设备厂商及ISO10816的各项要求。
For the pile-supported foundation and dynamic equipment system, DYNA5 is applied to calculate the stiffness and damping of the whole system under various operating frequencies. STAAD.Pro is applied to set up the reasonable modal. A series of dynamic stiffness, modal analysis, forced vibration analysis are performed to satisfy the requirements of the vendor and ISO 10816.
