| 摘 要： | 基于当前广泛应用的雨流计数法的原理,在全程实测某型越野车在某试验场各强化路段载荷谱的基础上.对载荷谱进行预处理,然后给出了基于雨流计数法的载荷谱压缩、外推、叠加与时域重构的应用实例.结果表明通过雨流计数法能在基本保持原载荷谱疲劳损伤的同时,明显地压缩载荷谱的时间历程,为下一步快速、高效地进行室内道路模拟试验打下了基础.

| Abstract: | The rain -flow counting method is discussed in this paper. Based on the loading spectra of a vehicle obtained from a standard test ground testing, a method is proposed for treating the actual measured data for load histories. The examples of the compression and extrapolation of loading spectra based on rain-flow counting are given, where the time scale is reduced remarkably. Then different roads in the test ground are combined to simulate the customer road. This research can pave the way for road simulation... |
