【摘要】 以通用曲柄压力机的曲轴作为分析研究对象，应用可靠性理论对其静态、动态可靠性做了分析描述，从疲劳强度的观点给出了曲轴的安全工作区。与传统的设计校核方法相比，动态可靠性分析更适合曲轴的分析设计。更多还原

【Abstract】 In this paper, the reliability of cranks was analyzed with static, dynamic reliability theories separately. It was derived that there was a safety working time for cranks in point of fatigue strength. By comparing the difference methods, the conclusion was given that the dynamic reliability analysis was more suitable than the two other method this paper described.更多还原
