Engineering tools for fatigue response due to pressure pulsation

泵和压缩机产生的压力脉动会给管道系统带来周期性的内部载荷，从而产生管道位移。严重的管道振动可能会导致疲劳失效。管网压力脉冲的产生、传播和结构响应是非线性的、三维的。这个项目的目的是确定、评估和设计一个真实复杂管道结构响应的最佳可用工具。目标是针对相同的测试用例分析和比较所有可用的模型，并应用最佳实用建模技术，并与已发布的实验数据集进行比较。这项工作的最终结果将是一套用于脉动服务管道系统疲劳分析的工程工具。

Pressure pulsation generated by pumps and compressors introduces periodic internal loading on piping systems that can generate pipe displacement. Significant pipe vibrations can build up which may lead to fatigue failure. The pressure pulse generation, propagation and structural response from the piping network are non-linear and 3D. The aim of this project will be to determine, assess and devise the best available tools for the structural response of a real complex piping structure. The objectives are to analyze and compare all available models against the same test case and apply the best practical modeling technique and compare with published experimental data sets. The final outcome of the work will be a set of engineering tools for fatigue analysis of piping systems in pulsation service.
