１农机链工作应力分析理论分析和试验研究表明，国产农机链的疲劳失效通常发生在内链板上，对标准农机链链段疲劳试验来讲，其工作应力可按正态分布处理。在高频疲劳试验机上，对链段进行加载时（正弦波形），最大载荷Ｆｍａｘ在一定范围内波动，其偏差约等于均值的５％，...
A theoretical analysis and experimental study on working stress analysis of agricultural machine chain shows that the fatigue failure of domestic agricultural machine chain usually occurs on the inner chain plate. For the fatigue test of standard agricultural machine chain segment, the working stress can be treated normally. In high-frequency fatigue testing machine, when the segment is loaded (sine waveform), the maximum load Fmax fluctuates within a certain range, the deviation is about equal to 5% of the mean, ...
