Abstract: The complex system structure makes the robot face the problem of frequent failures, which seriously affects the reliability of the device and the safety of the patients, and the reliability analysis and maintenance strategy of the lower limb exoskeleton rehabilitation robot are studied to reduce the occurrence of failures. Existing studies lack a comprehensive assessment and integrated analysis of the whole system, and optimizing the maintenance strategy to minimize the cost under the premise of ensuring system reliability remains an urgent challenge. This study proposes a systematic reliability assessment and preventive maintenance strategy for a lower limb exoskeleton rehabilitation robot. Based on the degradation model, the performance degradation process of each critical component is predicted, and a multi-objective optimization model is constructed by combining three kinds of costs to propose the optimal preventive maintenance strategy. Rehabilitation robot verify the effectiveness of the optimization method.
