| 中文摘要: |
| 利用当前广泛应用的雨流计数法原理结合Miner法则， 在全程实测某卫星运输至发射场各路段载荷谱的基础上， 利用雨流计数法对载荷谱进行预处理， 然后给出基于Miner法则对运输过程产生疲劳进行分析和评判的应用实例。为基于加速度信号的路谱载荷提出了一种切实可行的疲劳等效分析方法， 为在各种运输条件下， 评估产品所经受的力学环境和可能产生的疲劳损伤提供依据。 |
| 英文摘要: |
| The loading spectra of various road sections of satellite transport to launch site were measured based on the principle of current widely used rain flow counting method combined with Miner′ s rule. Pretreatment was carried out on the loading spectra using rain flow counting method. The application instance of analysis and evaluation on fatigue generated by the transport process based on Miner rule. A practical fatigue equivalent analysis method based on the acceleration signal spectrum loading for various transport conditions was put forward. The purpose was to provide reference for assessment of products withstanding mechanical environment and fatigue damage. |
