摘要
通过一定频率条件下的瓦楞纸板结构的疲劳剩余强度试验,对瓦楞纸板结构的疲劳剩余强度性能进行了初步探讨。发现不同载荷下,瓦楞纸板结构的疲劳强度均有提高。指出结构剩余疲劳强度上升的主要原因是,疲劳振动引起接触范围增大和接触面约束的增加。
The residual strength properties of the corrugated board structure were investigated by fatigue residual strength tests under a certain frequency.Under different loads,the main causes why fatigue residual strength of corrugated board structure was improved are the increasing contact area and enhancive interface constraint.
