针对不锈钢齿爪粉碎机的齿爪磨损过快、影响设备使用寿命和物料粉碎效果的问题，研究了齿爪磨损机理；并基于ANSYS Workbench仿真分析了齿爪的应力－应变及疲劳寿命。分析结果表明，齿爪失效的主要原因是周期性载荷作用导致的塑性变形和疲劳剥落。
針對不鏽鋼齒爪粉碎機的齒爪磨損過快、影響設備使用壽命和物料粉碎效果的問題，研究瞭齒爪磨損機理；併基于ANSYS Workbench倣真分析瞭齒爪的應力－應變及疲勞壽命。分析結果錶明，齒爪失效的主要原因是週期性載荷作用導緻的塑性變形和疲勞剝落。

The present study probed into existing problems of the stainless steel claw crusher, including equipment service life and material crushing efficiency influenced by too fast claw abrasion, investigated the mechanism of claw abrasion, and analyzed the stress-strain behavior and fatigue life of claw. The analysis results demonstrated that the main reasons for claw losing efficacy were periodic loading-induced plastic deformation and fatigue spalling.
