【摘要】 随着整个工业生产与现代科技的发展,机械产品性能日益提高,机械系统和工作环境更加复杂,产品的性能和可靠性问题也就越来越突出。因此研究机械产品的可靠性问题,就显得十分重要、非常迫切。机械可靠性设计的基本任务是在数学、力学、物理学、材料学与机械工程等研究的基础上,结合可靠性试验以及故障数据的统计分析,提供机械产品设计的数学力学模型、方法和实践。动态与渐变是机械产品不可避免的随时间变化的形态,对机械产品进行动态与渐变可靠性探究是可靠性研究的递进与升华。结合机械动力学、劣化机理、随机过程、概率统计、可靠性设计等理论与方法,阐述动态与渐变机械系统可靠性设计的理论与方法的内涵与递进,力图阐明机械工程领域动态与渐变可靠性设计概念思路、理论方法和工程实践,从而为机械设计、制造、使用提供坚实的理论支撑。更多还原

【Abstract】 Along with the development of industry and modern science,the performance of the mechanical product increases continuously and the mechanical system and work environment become more complex. The problems for the performance and reliability of the product become more and more prominent. It is very important and urgent to research the area of reliability of the mechanical product. Based on the research of mathematics,mechanics,material science and mechanical engineering,the basic task of mechanical reliability design is to propose mathematical-mechanical models and methods for engineering practice in mechanical product design by integrating the reliability experiment and statistical analysis of the failure data. Dynamic and gradual changing over time are universal characteristics of mechanical systems during service lifetime. Structural dynamic and time-dependent reliability analyses needs theories and methodologies in terms of mechanical dynamics,strength deterioration mechanism,random processes,probability theory,reliability analysis and design,etc. With the developments during past decades,methods on dynamic and gradual reliability analysis of system are reviewed.更多还原
