Abstract:In this paper, the reliability optimization problem in mechanical design is studied and discussed. Firstly, it introduces the background and significance of the research, as well as the research status and progress at home and abroad. Then, reliability analysis methods are summarized, including reliability theory overview, analysis methods classification and comparison, and the introduction of commonly used reliability analysis tools and software. Then, through the selection of a specific mechanical system reliability analysis case study, introduced the data collection and processing methods, reliability analysis results and interpretation. Next, the reliability problems in mechanical design are analyzed, including unreasonable design, parts quality problems, manufacturing process problems, poor operating environment and lack of reliability analysis and optimization. Finally, reliability optimization methods in mechanical design are proposed, including design rationality improvement, reliability analysis and fault prediction, material and manufacturing quality control, reliability testing and verification, and maintenance and maintenance planning. Through the comprehensive application of these methods, the reliability and performance of the mechanical system can be improved, its life can be extended, and the failure rate can be reduced.
