应用“四点相关法”估算沥青路面铣刨机铣刨滚筒轴的无裂纹寿命

Using "the method of Four Relative points"to Estimate Anti--fracture Life of Drum Shaft of Asphalt. Road--surface planer

本文根据科芬-曼森(Coffin-Manson)定理,利用材料的静拉伸试验数据,把材料在交变载荷作用下的塑性应变和弹性应变统一起来,应用“四点相关法”在双对数座标上绘制材料应变幅-载荷循环寿命曲线,在铣刨机设计阶段估算铣刨滚筒轴的无裂纹寿命.

According to Coffin-Manson Theorem and Test data of materiel,Using“the method of four relative points”,this paper estimated anti-fracture life of drum shaft of asphalt road surface planer.
