THEORY AND EXPERIMENT STUDY ON THE FATIGUE BEHAVIOR OF METAL SANDWICH PANEL
-
摘要: 金属面夹芯板以其良好的吸声降噪性能,被广泛用于声屏障中。而用于高速公路、高架桥道路、城市轻轨地铁以及铁路两侧的金属面夹芯板,则长期受到火车、汽车等经过时所引起的脉动风荷载作用,因此,对其疲劳性能的研究具有重要意义。首先,结合理论分析不同荷载作用下夹芯板能否发生疲劳破坏的几种情况;然后,通过有限元及试验研究验证了理论分析结果。结果表明:理论及有限元分析能反映夹芯板发生疲劳的条件。研究结果指出,由于规格的金属面夹芯板刚度较小,可不考虑脉动风荷载引起的疲劳问题。Abstract: THEORY AND EXPERIMENT STUDY ON THE FATIGUE BEHAVIOR OF METAL SANDWICH PANEL
