摘要
以管换热管为研究对象,介绍了基于Newmark-β法的载荷识别的正反分析原理。通过在MATLAB中编写相应程序,对单根换热管的振动进行载荷识别并计算,分析了传感器布置位置的不同对载荷识别测量结果的影响,从而给今后换热管振动的防振设计提供重要的参考。
Taking tube heat transfer tube as the research object,the principle of positive and negative analysis of load identification based on Newmark-beta method is introduced.Through the preparation of the corresponding program in MATLAB,vibration of single tube heat exchanger for load identification is calculated,analyzed the influence of the placement of sensor for different load identification results,provides an important reference for anti vibration design and vibration for heat pipe.
