| 摘 要： | 针对机械设计中存在的模糊信息 ,讨论了零件的应力同时受随机因素和模糊因素的影响时 ,用常规可靠性设计的仿真方法来模拟零件失效概率的方法。结果表明 ,常规可靠性设计方法由于没有考虑模糊信息 ,所得的结果与工程实践仍有差距 ;既考虑随机信息又考虑模糊信息 ,才可能得到比较理想的结果

| Abstract: | The paper discusses the method to imitate the failure probability of machine parts by means of the method of random imitation in general reliability design while stress is fuzzy and random because of fuzzy information in the process of mechanical design. It is demonstrated that the result of general reliability design may be different from that of engineering practice because fuzzy information is not taken into consideration, and that the result may conform to engineering practice when both random and fuzzy information is taken into consideration. |
