摘要
针对带有预应力的空间复杂管路结构,在静力分析的基础上,开展振动模态分析及随机振动响应分析,对比不同安装方式对管路的变形、应力、频率特性、随机振动响应的影响。通过研究给出内压、固定方式对管路动态特性的影响,为工程研究提供基础。
On the basis of the static structural analysis,vibration mode and response under random vibration are analyzed for a 3D prestressed pipeline.Then the effects of different mounting are studied for the pipeline.Based on the result,some valuable conclusions were given for the pipeline design.
