机械零件常规疲劳强度设计方法的研究

摘要

The influence by varying loads, fatigue damage most mechanical parts, making life shortened, to a certain extent affect the mechanical equipment performance into full play. Therefore, the strengthening investigate the fatigue strength of conventional mechanical parts design, to improve its anti-fatigue properties is important. In this paper, a clear step mechanical strength design, elaborated conventional design methods and calculation methods of fatigue fatigue strength is proposed to enhance the fatigue strength of mechanical parts design effective countermeasures, for reference.%受变荷载影响，多数机械零件容易疲劳破坏，使得使用寿命大大缩短，一定程度上影响机械设备性能的充分发挥。因此，加强机械零件常规疲劳强度设计，对提高其抗疲劳性能具有重要意义。本文明确机械强度设计的步骤，阐述常规疲劳设计方法及疲劳强度的计算方法，提出了提升机械零件疲劳强度的有效设计对策，以供参考。
