【Abstract】 Theoretical and experimental research on the laser energy supply technology is made. Based on the Arrhenius model, the inverse power model and the generalized log-linear model of Nelson, the multi-stress life prediction model of the laser energy supply system is established. The life prediction model obtains the actual reliability curve according to different temperature stresses and voltage stresses, thereby estimating the reliability of the entire laser energy supply system. According to the reliability, the replacement time of the parts of the system is determined, and the timely replacement of the parts is completed to ensure long-term and efficient work and avoid the sudden situation caused by the damage of the parts. On this basis, the practical prototype of the laser energy supply system is developed, and the estimated life of the estimated energy supply system under various conditions is simulated according to the actual parameters of the prototype. The theoretical analysis results show that the ideal life of the system under normal stress conditions(25 ℃/5 V)is 10 500 h, which lays a foundation for further experimental verification. This research effectively improves the reliability and stability of laser energy supply technology, and provides a better guarantee for the wide application of this technology in the power industry.更多还原
