【摘要】 采用线切割预制齿轮初始裂纹 ,对高频淬火齿轮进行随机断裂试验 ,观察了疲劳裂纹扩展方向和断口形貌。结果表明疲劳裂纹扩展方向与有限元法计算结果十分接近更多还原

【Abstract】 The crack initiation and the fracture appearance of the random fracture are analyzed by the test for induction hardened gears.The primary cracks of the gear surface are made by EDM. The result of the test is very close to that calculated by FEM.更多还原
