摘要
齿轮传动系统是一个串联系统,但在系统与零件之间的关系、系统实现功能的方式、以及系统的时间属性等方面与传统意义上的串联系统有明显不同。从可靠性分析的角度,详细分析了齿轮传动系统在系统构型、载荷传递及失效等方面的特点。鉴于可靠性分析的需要,细化了机械系统分类,把串联系统划分为简单(空间或空域)串联系统(常构串联系统)和时域串联系统(变构串联系统)。根据在功能、结构、载荷等方面不同的系统,有针对性地研究可靠性分析与可靠性建模方法。以单级齿轮传动系统为例,建立了不同系统结构参数、不同服役条件下的系统可靠性模型,展示了系统可靠性变化规律,以及所建模型与传统串联系统模型之间的差异。
Gear transmission system is a series system. However, it is different from the traditional series system in many aspects such as the relationship between system and elements, the manner for the system functioning, the time-dependent system configuration, etc. System classification is discussed firstly to meet the demand of system reliability modeling. For the purpose of system reliability analysis, a gear transmission system is taken as a time-dependent varying configuration system, which is different from the traditional series system with changeless configuration in space. According to different function, different configuration and different load characteristics, specific system oriented reliability analysis and modeling method are studied. Taking simple gear transmission system as an example, several system reliability models are developed, the reliability variation with load number and the differences between the new model and traditional model are illustrated.
