Abstract
As the degree of automation in manufacturing continues to increase, automated assembly systems are becoming increasingly prevalent in modern industrial production, with their reliability directly impacting product quality and production efficiency. To enhance the reliability of automated assembly systems, this study conducts an in-depth analysis of existing systems, focusing on a typical automated assembly system as the research subject. By addressing fault issues encountered during its operation, this research employs methods such as Failure Mode and Effects Analysis (FMEA) and reliability allocation to evaluate the system's reliability. A system reliability model is constructed to identify key factors influencing reliability, including hardware failures, software errors, and human-machine interaction mistakes, while thoroughly analyzing the mechanisms by which these factors operate. Based on this analysis, a series of improvement measures are proposed, such as optimizing hardware design to enhance interference resistance, refining software algorithms to minimize logical errors, and intensifying operator training to reduce the probability of human error. Simulation validation and practical application tests demonstrate that implementing these improvements significantly extends the mean time between failures and markedly reduces the failure rate, thereby substantially improving overall system reliability. This study provides valuable methods and insights for enhancing the reliability of similar systems, offering significant theoretical implications and practical value.
