| 摘 要： | 以航天器使用的谐波齿轮减速器为研究对象,在不同信息来源的不确定性处理方法的基础上,研究认知不确定性和客观不确定性同时存在时的概率——非概率可靠性混合模型。建立航天器使用的谐波齿轮减速器的可靠性分析模型,并对模型中的参数进行了灵敏度分析。该方法不用搜索极限状态方程的设计验算点,有较高的鲁棒性。

| Abstract: | Since the constraints of various objective reasons and conditions,the lack of data exists in reliability engineering widely,especially in reliability-based design of aerospace.There is large amount subjective information exists in initialize data.Traditional reliability analysis method,such as probability-based method,can not handle the situation when both epistemic and aleatory uncertainties are presented in the system,the results acquired by probability-based method have large errors when used in practica... |
